A cracked plastic tank or a slow seep from the core seam can turn a routine commute into an overheated headache in minutes. For the WK2 Grand Cherokee, the radiator sits at the front of a demanding cooling loop that handles a heavy SUV, stop-and-go traffic, and often a V8’s thermal load — so picking a replacement that actually holds up under real driving conditions matters more than just matching the bolt pattern.
I’m Amir — the founder and writer behind Four Wheel Ask. My approach to this guide is rooted in months of cross-referencing OEM specifications, studying material grades, analyzing owner-reported failure points, and comparing warranty terms across a wide range of aftermarket and premium suppliers to separate parts that deliver lasting performance from those that cut corners.
After evaluating hundreds of owner reports, the ideal best 2014 jeep grand cherokee radiator balances cooling efficiency with durable construction.
How To Choose The Best 2014 Jeep Grand Cherokee Radiator
The WK2 platform shipped with multiple engine options and two distinct cooling packages, so a one-size-fits-all approach leads to fitment headaches or chronic overheating. Understanding three key factors will help you match the right radiator to your specific build and driving conditions.
Core Construction & Material Quality
Most factory radiators use a brazed aluminum core with nylon-reinforced plastic tanks. The plastic-to-metal crimp seam is the most common failure point — heat cycling causes the plastic to become brittle and crack, typically around the three-to-five-year mark. Aftermarket alternatives range from all-aluminum welded cores (heavier duty but require precise fitment) to more affordable units that mirror the OEM design with slightly thicker tank walls. For daily-driven Grand Cherokees, a well-made hybrid unit with reinforced tank material and double header plates offers the best balance of cost and longevity.
Fitment by Engine & Cooling Package
The 3.6L Pentastar and the 5.7L/6.4L Hemi use different radiator part numbers, and the Heavy Duty Cooling option (typically found on V8 models with towing packages) uses a thicker core with a higher fin density. Installing a standard-duty radiator on a Heavy Duty-equipped V8 will likely result in higher coolant temps under load. Always verify your VIN against the radiator’s OEM reference numbers — a mismatch of even one digit can mean wrong inlet/outlet diameters or missing transmission cooler ports.
Warranty & Post-Purchase Support
Radiator failures often surface months after installation, not days. A limited lifetime warranty sounds reassuring, but many aftermarket brands require the original purchaser to jump through hoops — proof of professional installation, no coolant additives, and return shipping at your cost. A six-month or one-year warranty that the manufacturer honors without hassle is worth more than a lifetime clause that takes weeks of back-and-forth to enforce.

In‑Depth Reviews
1. TRQ RDA86794 Radiator
The TRQ RDA86794 targets owners who want a premium-tier replacement without paying dealer-level pricing. This radiator is designed as a direct OE replacement for the 2014-2021 Grand Cherokee across the 3.6L, 5.7L, and 6.4L engines, and it also covers compatible Dodge Durango years. The core dimensions measure 25.06 inches wide by 20.39 inches tall, and the unit includes transmission cooler fittings pre-configured for automatic transmission models.
Build quality stands out as a consistent theme in owner reports. The aluminum core uses precision-folded louvered fins that maximize surface area for heat rejection, and the plastic tanks benefit from reinforced nylon construction that resists the thermal cracking seen in cheaper units. Packaging receives frequent praise — multiple reviewers noted the thick foam and multi-layer cardboard protection ensured no transit damage, which is a common frustration with budget radiators.
Fitment feedback is overwhelmingly positive for the 5.7L and 3.6L applications, with owners reporting a 2-hour DIY installation time. The four fan shroud clips require care during transfer from the old unit, but otherwise all hose connections and transmission cooler line ports align correctly. The core thickness matches the standard-duty specification, so owners with the Heavy Duty cooling package should verify compatibility before purchasing.
What works
- Exceptional packaging prevents shipping damage
- Aluminum core with louvered fins for efficient cooling
- Transmission cooler fittings match OEM configuration
What doesn’t
- Not verified for Heavy Duty cooling package fitment
- Radiator cap sold separately
2. Mishimoto MMRAD-WK2-12 Radiator
The Mishimoto MMRAD-WK2-12 exists in a different league than most aftermarket radiators. Designed specifically for the 2012+ Jeep Grand Cherokee SRT-8 (and confirmed by owners to fit the 2014 SRT and 3.6L models with some bracket work), this is a full TIG-welded aluminum core that increases coolant volume by 95 percent over the stock radiator. The core is 66 percent thicker than the factory unit, which translates directly into greater thermal mass and heat rejection capacity under sustained load.
Owners who track their Grand Cherokee or tow frequently report a measurable drop in coolant temperatures — one verified owner documented a 20-degree reduction on a 3.6L that was previously running hot. The kit includes a Mishimoto radiator cap, a magnetic drain plug for catching metallic debris, and A/C condenser brackets plus fan shroud brackets to simplify the swap. The lifetime warranty is among the strongest in the category, though one owner reported a core leak at the three-year mark and had to navigate the claims process.
Installation requires removing the front bumper for proper access, and the included brackets need some trial-and-error positioning to achieve a solid mount. The all-aluminum construction means no plastic tanks to crack, but it also means the radiator is heavier at 21 pounds and less forgiving of minor alignment errors during installation. For owners who prioritize maximum cooling overhead and plan to keep their Grand Cherokee long-term, this unit represents a genuine upgrade rather than a maintenance replacement.
What works
- 95 percent increase in coolant capacity over stock
- All-aluminum welded construction eliminates tank seam failures
- Includes magnetic drain plug and radiator cap
What doesn’t
- Requires front bumper removal for installation
- Premium price point places it beyond basic replacement budgets
3. TYC 13204 Radiator
TYC has supplied cooling components to the automotive aftermarket for over two decades, and the 13204 model reflects that engineering pedigree. This radiator is a direct OE replacement for the 2011-2020 Jeep Grand Cherokee, with OEM reference numbers tracing back to Mopar part 55038001AH. The construction uses premium-grade aluminum tubes paired with precision-folded louvered fins, and TYC adds internal tank ribs, expansion grooves, and double header plates to reinforce the areas most prone to stress cracking.
Owner feedback for 2014 Grand Cherokee fitment is notably consistent. Multiple verified purchasers with the 3.6L Limited trim reported that the radiator dropped in without modification and that the AC condenser clips engaged securely. One owner noted the aluminum core was slightly wider than the factory unit but confirmed that overall dimensions matched and installation went smoothly. The thicker core compared to standard replacement units was also noted by a 2013 Overland owner who appreciated the extra cooling margin during summer towing.
However, durability questions surface in a minority of reports. One owner documented a small leak starting just eight days after installation on a 2015 model, and TYC’s warranty process required the original receipt and proof of purchase from an authorized retailer — a hurdle that left them without a resolution. The majority of reviews show years of trouble-free service, but the inconsistency in quality control is worth noting for buyers who want absolute peace of mind.
What works
- Double header plates and internal ribs strengthen high-stress zones
- Direct OE fitment for 3.6L and 5.7L models
- Aluminum inlet rings resist corrosion better than standard steel
What doesn’t
- Warranty enforcement requires strict documentation
- Small batch of early failure reports raises consistency concerns
4. KAX CU13200 Radiator
KAX brings an IATF16949 certification to the table, meaning their manufacturing facility follows automotive-grade quality management standards. The CU13200 is compatible with the 2011-2021 Grand Cherokee across the 3.6L, 5.7L, and 6.4L engine options, plus the 2011-2024 Durango with applicable cooling packages. Core dimensions measure 25-1/16 inches wide by 20-1/2 inches tall with a 5/8-inch thickness — matching the standard-duty specification for most Grand Cherokee trims.
The radiator uses high-density multi-louvered fins that increase the heat dissipation area compared to a flat-fin design. All units undergo leak testing, pressure testing, and aging/durability validation before shipping. The packaging strategy is notably robust: multi-layer cardboard with foam corner locks and internal bubble column protection to prevent the core from bending during transit — a common failure point for budget radiators that arrive with crushed fins.
Owner reports for the 5.7L and 3.6L Grand Cherokee show consistent fitment with no modification needed. One verified buyer noted the unit fit exactly like the OEM radiator and that the package was well-protected. Another owner highlighted the two-year warranty as a differentiator in this price range, though one negative review on a different vehicle application reported a leak after 45 days with slow manufacturer response. The 5/8-inch core thickness means this radiator is not designed for Heavy Duty cooling system applications.
What works
- IATF16949 certified manufacturing ensures consistent quality
- Two-year warranty exceeds typical six-month coverage
- Reinforced packaging protects core during shipping
What doesn’t
- 5/8-inch core insufficient for Heavy Duty cooling package
- Isolated reports of slow customer service response
5. YITAMOTOR Radiator
YITAMOTOR positions this radiator as a direct OE replacement for the 2011-2021 Grand Cherokee and 2011-2021 Dodge Durango, covering the 3.6L, 5.7L, and 6.4L V8 engine options. The core dimensions are 25.4 inches wide by 20.39 inches tall, and the unit uses high-density aluminum tubes and fins to maximize the radiation area for heat dissipation. The inlet and outlet tanks are constructed from high glass fiber reinforced nylon PA66, a material grade known for better heat resistance and dimensional stability under thermal cycling.
Seamless welding between the aluminum core and the plastic tanks reduces the risk of crimp-seam failure, which is the most common failure mode on factory radiators. Each unit is leak-tested before packaging, and YITAMOTOR uses PE foam with multi-layer cardboard to protect the core during shipping. The package includes a clear installation instruction sheet, though the radiator cap is not included and must be purchased separately.
Owner feedback across multiple vehicle platforms — including a 2001 Jeep 4.0, a GMC Safari van, and a Ford Ranger — is consistently positive, with owners noting easy installation, no leaks, and reasonable pricing. For the Grand Cherokee specifically, the fitment aligns with the standard-duty cooling specification. The PA66 tank material is a genuine upgrade over standard nylon, but long-term durability data beyond one year of service is still limited in the review pool.
What works
- PA66 nylon tanks offer superior heat resistance
- Seamless welding reduces crimp-seam failure risk
- Leak-tested before shipment with robust packaging
What doesn’t
- Radiator cap not included in the box
- Limited long-term reliability data beyond one year
6. DNA Motoring OEM-RA-13200 Radiator
DNA Motoring uses a T-6061 aluminum core with a 1-inch depth for the OEM-RA-13200, making it one of the thicker standard-duty options in this segment. The fitment covers the 2011-2015 Grand Cherokee 3.6L, 2011-2013 Grand Cherokee 5.7L, and 2014-2021 Grand Cherokee 5.7L with standard-duty cooling, plus compatible Durango years. The inlet and outlet diameters are both 1-1/2 inches, matching the factory hose connections.
The core is constructed as a 1-row design with T-6061 aluminum, which offers better tensile strength than the 6000-series alloys found in many budget radiators. The ABS plastic tanks are crimped to the core using a full-perimeter seal, and the unit includes no oil cooler provisions — it relies on the vehicle’s external transmission cooler, which is standard on Grand Cherokee automatic transmission models. At just under 12 pounds, the radiator is manageable for a solo installer.
Owner reports for Grand Cherokee fitment are generally positive, with one verified buyer noting the unit fit exactly like the OEM radiator. However, a verified owner of a 2015 Durango R/T reported that the radiator did not fit properly — missing molded clips for the condenser and transmission cooler support. The packaging also drew criticism in that case, with the box arriving damaged and parts of the radiator protruding through the cardboard. This suggests quality control in packaging varies between shipments.
What works
- 1-inch core depth offers robust cooling capacity
- T-6061 aluminum provides excellent structural integrity
- Lightweight design at under 12 pounds
What doesn’t
- Inconsistent packaging quality for some shipments
- Not compatible with Heavy Duty cooling package or R/T models
7. PHILTOP CU13200 Radiator
PHILTOP enters the Grand Cherokee radiator space with a broad compatibility list that spans the 2011-2021 WK2 platform. The CU13200 covers the 3.6L, 5.7L, and 6.4L engines, as well as compatible Durango years up to 2024. The OEM reference numbers include 52014529AB, 55038001AF/AG/AH, and 55038185AB/AD/AE — covering most iterations of the factory radiator across the production run.
The core uses high-density multi-layer cooling fins designed to maximize heat dissipation in a compact package. IATF16949 certification is claimed, indicating the manufacturing facility follows automotive-grade quality standards. The unit is designed as a direct bolt-on replacement with no drilling or modification required, which aligns with owner feedback across multiple vehicle platforms including a 1998 Chevy Suburban and a 2015 Jeep Wrangler JK.
One critical verification point: a 2017 Grand Cherokee 5.7 Hemi owner reported that the radiator listed as compatible with Heavy Duty cooling actually had a 5/8-inch core depth, not the expected 1-inch depth for the HD package. This suggests the listing may conflate standard-duty and heavy-duty fitment. Owners with the HD cooling option should measure their existing core depth before ordering. For standard-duty applications, the build quality and fitment receive positive marks across most reviews.
What works
- Broad vehicle coverage across many model years
- Multi-layer fins improve cooling efficiency
- IATF16949 certified manufacturing
What doesn’t
- Listed Heavy Duty compatibility may be inaccurate
- Core depth insufficient for true HD cooling applications
8. Nilight RAD907 Radiator
Nilight’s RAD907 covers the 2011-2020 Grand Cherokee and Dodge Durango with 3.6L, 5.7L, and 6.4L engine options, making it one of the broadest fitment listings at its price point. The construction uses an ABS plastic tank and aluminum core combination that mirrors the OEM design, and each unit undergoes 100 percent leak testing before shipment. The core is designed to maintain proper cooling system pressure and increase the boiling point of the coolant.
The six-month warranty is shorter than the aftermarket average, which becomes relevant when reading owner experiences. One verified purchaser reported that the radiator cracked at the plastic tank seam less than a year after installation, and the warranty process redirected them between Amazon and Nilight without resolution. This pattern — a low upfront cost followed by limited post-failure support — is the primary risk with this choice.
On the positive side, owners who had successful installations reported a perfect fit and good cooling performance. A 2015 Dodge Grand Caravan 3.6L owner noted the radiator worked like a charm after following the proper fill procedure. For budget-conscious owners who plan to sell the vehicle within a year or who want a temporary solution while saving for a premium unit, the Nilight offers functional cooling at a minimal investment.
What works
- Broad vehicle compatibility across multiple engine options
- 100 percent leak-tested before shipping
- Lowest entry price point in the comparison
What doesn’t
- Six-month warranty leaves limited protection window
- Plastic tank cracking reported within one year by some owners
9. Autoshack RK1702 Radiator
The Autoshack RK1702 is a 1-row aluminum and plastic radiator covering the 2011-2021 Grand Cherokee and 2011-2024 Durango with 3.0L, 3.6L, 5.7L, 6.2L, and 6.4L engine options. The core width measures 20.56 inches and core height is 25.06 inches, with a single-row configuration that keeps weight down to 10.8 pounds. No engine oil cooler or transmission oil cooler is integrated — the vehicle’s external coolers handle those duties.
Fitment feedback for the 2014 Grand Cherokee Overland 3.6L is specifically documented in owner reviews. One verified purchaser reported that the fit was perfect for their Overland, though they noted the installation takes three to four hours and recommended bumper removal for easier access. The same owner noted the build quality is lighter than the factory radiator but confirmed it worked perfectly after 1,000 miles of mountain driving. Another 2014 Grand Cherokee owner gave it a perfect score, praising the fitment.
A counterpoint comes from an owner who reported a leak at the five-month mark, within the six-month warranty window. The warranty process required going through Amazon rather than Autoshack directly, and the owner was unable to secure a refund or replacement before the warranty expired. This highlights a critical vulnerability: a budget price paired with a warranty process that may not deliver timely support if the part fails.
What works
- Perfect fit confirmed by 2014 Grand Cherokee Overland owners
- Lightweight design at 10.8 pounds eases installation
- Covers a wide range of engine configurations
What doesn’t
- Warranty process may not provide timely support
- Build quality feels lighter than OEM construction
10. AUTOSAVER88 Radiator
This AUTOSAVER88 radiator is designed for the 2014-2018 Jeep Cherokee (KL), not the Grand Cherokee (WK2). The fitment covers the L4 2.4L Tigershark and the V6 3.2L Pentastar engines, with OEM replacement numbers 68229290AA and 68284108AA. The construction uses a high-grade plastic tank bonded to an aluminum core, with high-density multi-louvered fins for maximum cooling efficiency in both hot and cold weather extremes.
Owner feedback across multiple Cherokee trims is overwhelmingly positive, with a 4.8-star average across five verified reviews. One owner of a 2016 Cherokee 4×4 reported a perfect fit. Another owner noted the hooks at the bottom of the radiator required slight modification — the cooling fan mounting points did not align perfectly, requiring zip ties to secure the fan shroud. This suggests the tooling tolerances may vary slightly from the factory geometry.
The price point is notably lower than Jeep dealership pricing, with one owner estimating savings of around three hundred dollars compared to a dealer replacement. The packaging receives consistent praise for protecting the core during transit. This unit is a strong option for Cherokee KL owners looking for a budget-friendly direct replacement, but Grand Cherokee WK2 owners should verify they are ordering the correct platform — the Grand Cherokee uses different mounting points and core dimensions.
What works
- Significant savings compared to dealership pricing
- High-density louvered fins for efficient cooling
- Well-protected packaging during shipping
What doesn’t
- Designed for Jeep Cherokee KL, not Grand Cherokee WK2
- Fan shroud mounting hooks may require minor adjustment
11. Readair 13401 Radiator
The Readair 13401 is specifically engineered for the 2014-2018 Jeep Cherokee with the 2.4L L4 (dual fans) and the 3.2L V6 — but only with manual transmission. This distinction is critical because the radiator core and transmission cooler plumbing differ between manual and automatic configurations. The OEM reference number 68229290AA matches the factory part, and the unit uses an aluminum core with plastic tanks in a direct-fit configuration.
Owner feedback across multiple vehicle platforms reveals a pattern of good fitment and reliable cooling. One verified owner installed this radiator in a 2006 Honda Accord EX 6-speed manual and reported a perfect fit with no modifications required. Another owner noted it worked well for their 2011 BMW 328i xDrive after adding a compatible Mercedes sensor. The packaging is described as genius-level protection, with extra support around the vulnerable fin areas.
For Grand Cherokee owners, this unit is not a direct match — the Cherokee KL platform has different core dimensions and mounting points. However, for owners with a 2014-2018 Jeep Cherokee KL manual transmission who are looking for an affordable alternative to the dealer part, the Readair 13401 offers proven fitment and good build quality at a competitive price point. One owner of a 2011 Jeep Wrangler JK also confirmed a nice fit, noting it was the third one they had installed and recommending against all-aluminum radiators for that application.
What works
- Perfect fit for manual transmission Cherokee KL models
- Excellent packaging with reinforced corner protection
- Proven reliability across multiple vehicle platforms
What doesn’t
- Not compatible with automatic transmission configurations
- Designed for Jeep Cherokee KL, not Grand Cherokee WK2
Hardware & Specs Guide
Core Construction & Materials
Every radiator in this review uses an aluminum core for heat transfer, but the grade and thickness vary significantly. Standard-duty cores range from 5/8 inch to 1 inch thick, with 1-inch cores offering greater thermal mass for sustained loads. Tank material is the bigger differentiator: basic units use standard nylon, while premium options like YITAMOTOR use PA66 glass-fiber-reinforced nylon that resists thermal deformation. All-aluminum welded cores, as seen in the Mishimoto, eliminate plastic-to-metal crimp seams entirely — the most common failure point on factory radiators.
Cooling System Pressure & Capacity
The 2014 Grand Cherokee cooling system operates at a pressure of approximately 16 psi, and the radiator cap seals this pressure to raise the coolant boiling point. Most aftermarket radiators match the factory core volume, but performance units like the Mishimoto increase coolant capacity by up to 95 percent. Transmission cooler integration varies — some radiators include an internal cooler loop, while others rely on the vehicle’s external cooler. Always verify that the replacement matches your vehicle’s transmission cooling configuration before ordering.
