When the high-pressure refrigerant line fails or the clutch seizes on a 2.4L K24 engine, the cabin of a 2008 Honda CR-V turns into a humid greenhouse faster than you can roll down the windows. That distinct hot-air blow from the vents isn’t just uncomfortable—it signals that the TRSE09 compressor has given up, often taking the entire A/C system down with it. Choosing the right replacement means matching the 7-groove pulley, the PAG 100 oil charge, and the exact OE dimensions that this chassis demands.
I’m Amir — the founder and writer behind Four Wheel Ask. I’ve spent years analyzing automotive HVAC replacement data, cross-referencing compressor fitment charts, and studying owner-reported failure patterns across the K24 engine family to separate parts that bolt on from parts that last.
This guide walks through nine verified options for the 2008 honda cr-v ac compressor, covering everything from direct-replacement units to full-system kits that include the receiver drier and expansion device.
How To Choose The Best 2008 Honda CR-V AC Compressor
The 2008 CR-V uses the TRSE09 axial-piston compressor design, a compact unit that delivers reliable cooling when paired with the correct PAG 100 oil and a properly flushed system. Beginners often assume any compressor with the right mounting holes will work, but the pulley groove count, clutch diameter, and electrical connector pinout must match exactly to avoid belt alignment issues or clutch engagement failures.
Verify the TRSE09 Compressor Type and Pulley Specs
Every 2.4L CR-V from 2007 through 2011 uses the TRSE09 model. Look for a 7-groove pulley with a 106 mm diameter. A mismatched pulley will cause the serpentine belt to ride incorrectly, leading to slippage, noise, and reduced alternator output. The OE part numbers 38810RWCA03 and 38810RZYA01 confirm correct fitment for the LX, EX, and EX-L trims—the Touring and SE trims require different components.
Check the Oil Type and Pre-Fill Quantity
The system requires PAG 100 viscosity oil, and the compressor must be pre-filled with 120±10 mL. Using the wrong oil grade, such as PAG 46 or PAG 150, will cause internal wear or foaming. Some aftermarket compressors ship with shipping oil that must be drained and replaced with fresh PAG 100 to match the vehicle’s specific refrigerant and evaporator capacity.
Evaluate Whether a Full Kit or Bare Compressor Fits Your Situation
A failed compressor often sends metal debris through the A/C loop, contaminating the receiver drier, expansion valve, and condenser. If you are uncertain about the system’s cleanliness, a full repair kit that includes a new accumulator, o-ring seal kit, and expansion device is the safer route. A bare compressor makes sense only when the system was professionally flushed and the old drier replaced separately.

In‑Depth Reviews
1. Denso 471-7056 A/C Compressor
Denso supplies original equipment compressors for many Honda vehicles, and the 471-7056 carries that same factory-level engineering. The TRSE09 body is machined with tight piston clearances and uses a properly sized PAG 100 oil charge, so you don’t need to drain and refill before installation. The 7-groove pulley with 106 mm diameter lines up exactly with the K24’s serpentine belt routing, preventing the whine that often comes from aftermarket units with looser tolerances.
What sets this unit apart is the consistent clutch engagement voltage. Many lower-priced compressors suffer from partial engagement at low RPM because the coil winding resistance drifts, but the Denso clutch snaps in cleanly every time. The housing is die-cast aluminum with a corrosion-resistant coating that holds up against road salt exposure—a common concern for CR-V owners in colder climates who run the defroster regularly.
The trade-off is the premium positioning, but for owners who plan to keep their CR-V for the long haul, the reliability savings across multiple seasons offset the initial cost. Just confirm that your old electrical connector pins are in good shape, as the Denso unit uses the standard 3-pin layout that matches the 2008 harness.
What works
- Factory-level machining tolerances ensure quiet operation
- Pre-filled with correct PAG 100 oil
- Consistent clutch engagement across all RPM ranges
What doesn’t
- Higher cost than aftermarket alternatives
- Does not include drier or expansion valve
2. BuyAutoParts 60-82560R6 A/C Kit
When a compressor grenades internally, metal shavings travel through the entire A/C loop, embedding in the condenser fins and clogging the receiver drier. The 60-82560R6 from BuyAutoParts solves that by bundling a new compressor with a fresh condenser, accumulator, expansion device, and a complete o-ring seal kit. This is the go-to choice if you are pulling the old system completely and want one box with every part that touches refrigerant.
The compressor meets ISO/TS 16949 manufacturing standards, meaning the internal bore and piston clearances are held to the same statistical process control used by Tier 1 OEM suppliers. The condenser has the correct parallel-flow core design for the CR-V’s front-end packaging, matching the 2007-2011 radiator support bracket positions exactly. You won’t need to drill new mounting holes or trim plastic shrouds to get a proper fit.
At 25 pounds, this kit ships heavy, but everything inside is pre-inspected and individually bagged. The two-year unlimited-mileage warranty provides peace of mind that a bare compressor alone cannot match. Professional installation is strongly recommended, given the system evacuation and recharge required after replacing the condenser.
What works
- All critical components in one shipment
- ISO/TS 16949 certified compressor
- Two-year warranty covers the whole bundle
What doesn’t
- Heavy package increases shipping cost
- Requires full system evacuation and professional recharge
3. BuyAutoParts 60-81204RK Repair Kit
This kit sits between a bare compressor and the full condenser-bundle option. It pairs the same ISO/TS 16949 compressor from BuyAutoParts with a new accumulator, expansion device, and o-ring set—everything needed for the high-pressure side replacement if your condenser is still clean. The accumulator is pre-charged with desiccant, so you don’t have to estimate the correct moisture-absorbing capacity for the CR-V’s 5.3-liter system capacity.
The compressor body is painted rather than polished, which helps resist surface corrosion if you live in a humid region. The clutch assembly is pre-gapped from the factory at the correct 0.5 mm air gap, saving you the hassle of feeler-gauging the clutch plate shims during installation. This matters because an incorrect air gap causes the clutch to slip under load, producing that burnt-rubber smell inside the cabin.
The two-year warranty is notably longer than the industry-standard one-year coverage. The only caveat is that the expansion valve is a generic unit that may not have the exact orifice size as the Honda original, potentially altering the superheat setpoint. Most HVAC professionals will adjust the charge accordingly, but purists may prefer an OEM expansion valve.
What works
- Pre-gapped clutch saves installation time
- Includes accumulator and expansion device
- Two-year unlimited-mileage warranty
What doesn’t
- Expansion valve is generic, not OE-spec
- Excludes condenser
4. Universal Air CO4920AC Compressor
Universal Air Conditioning produces compressors that see heavy use in commercial fleet vehicles, and their CO4920AC brings that ruggedness to the CR-V application. The TRSE09 unit is built in an ISO/TS 16949 certified facility, so the piston and cylinder bore tolerances meet the same standards Honda applies to its own supplier base. The clutch coil is wound with enameled copper wire rated for continuous-duty cycling, which reduces the failure rate when the compressor cycles on and off frequently in stop-and-go traffic.
The compressor weighs under a pound more than some budget alternatives, which comes from using a thicker mounting flange and larger-diameter clutch hub. That extra mass helps damp vibration at idle, where the K24’s natural harmonics can sometimes excite the sheet metal of the A/C lines and produce a buzzing noise through the firewall. The included mounting bracket and gaskets match the original CR-V hardware with no filing or slotting needed.
One area to watch is that the compressor ships with a generic shipping oil. You must drain this and refill with the correct PAG 100 quantity before installation, or the internal vanes may not seal properly during the first few rotations. Professional installers will catch this, but DIYers should double-check the label on the oil bottle.
What works
- Thicker flange reduces vibration transfer
- ISO/TS 16949 quality certification
- Includes mounting brackets and gaskets
What doesn’t
- Ships with generic oil that must be replaced
- No accumulator or seals included
5. UAC CO 4920AC Compressor
UAC has been a steady supplier of aftermarket A/C compressors for over two decades, and the CO 4920AC reflects that manufacturing maturity. The TRSE09 body is assembled with a low-friction piston coating that helps the compressor spin more freely at idle, reducing the slight load hum that some CR-V owners report with budget compressors. The 7-groove pulley maintains belt tension without squeaking, even when the A/C is engaged at full defrost on a cold morning.
The compressor comes pre-charged with shipping oil, but UAC specifies that the oil must be drained and replaced with the correct PAG 100 for your specific system. This step is critical because the shipping oil’s viscosity is chosen for preservation during storage, not for lubrication during operation. The clutch and pulley assembly are balanced as a unit, which minimizes wobble at high RPM when the K24 is spinning above 3,000 RPM on the highway.
Installation is straightforward for anyone comfortable removing the front passenger side wheel well liner, which provides access to the compressor bolts. The unit does not include a new accumulator or o-ring kit, so budget for those separately if your system is contaminated. The one-year warranty is standard but matches what most regional auto parts stores offer on house-brand compressors.
What works
- Low-friction coating reduces idle noise
- Balanced clutch/pulley assembly minimizes wobble
- Proven two-decade brand presence
What doesn’t
- Shipping oil must be drained and replaced
- No drier or o-rings in the package
6. Autodevil A/C Compressor
Autodevil positions this compressor as a direct replacement for the 2007-2011 CR-V 2.4L, and the TRSE09 housing dimensions match the original within a fraction of a millimeter. The 7-groove pulley uses the same 106 mm diameter, and the clutch is pre-installed with the correct air gap, so you don’t need to transfer components from your old unit. The compressor is pre-filled with PAG 100, eliminating the oil-drain step that some other aftermarket units require.
The high-efficiency motor claim refers to the reduced internal friction from the axial-piston design, which does cut the parasitic load on the K24 engine slightly. In real-world driving, the difference is most noticeable at idle when the A/C is engaged—the engine RPM drop is less pronounced compared to a worn or seized original compressor. The aluminum casing has a smooth finish that resists minor stone impacts from road debris.
The main downside is the bare-bones packaging. You get the compressor and clutch only—no accumulator, no o-rings, no gaskets. If your system has contamination from a previous failure, you will need to purchase those components separately. The one-year warranty matches the industry baseline, but the unit’s long-term track record is still building compared to more established brands like Denso or UAC.
What works
- Pre-filled with correct PAG 100 oil
- Reduced parasitic load at idle
- Direct fit without clutch transfer
What doesn’t
- Bare unit with no accessories
- Limited long-term reliability data
7. ILONPA CO 4920AC Compressor
The ILONPA compressor uses a high-strength aluminum alloy housing that dissipates heat more effectively than standard castings. This matters for the 2008 CR-V because the compressor sits low on the passenger side of the K24, near the exhaust manifold heat—a hostile thermal environment that accelerates seal degradation on compressors with inferior material composition. The TRSE09 internals are assembled with a focus on reducing vibration, and the aluminum construction contributes to the overall quieter operation compared to some steel-bodied units.
The unit includes the clutch, mounting brackets, and gaskets in the box, so you have all the hardware needed for a swap. The PAG 100 oil is pre-filled at the factory, and ILONPA specifies that no additional oil should be added before installation. Overfilling a TRSE09 compressor can cause hydraulic lock and immediate seal failure, so the pre-set charge is a genuine convenience for DIY installers who lack a graduated cylinder.
The lower fuel consumption claim is subtle—the compressor reduces internal drag by about 5-8% compared to a worn original, which translates to a barely measurable improvement in highway MPG. The real gain is the consistent cooling output on hot days, where the aluminum housing helps maintain lower discharge temperatures at the condenser inlet. The one-year warranty is standard, but the included mounting brackets make it a better overall package than many bare compressors at a similar price point.
What works
- Aluminum housing improves heat dissipation
- Comes with brackets and gaskets
- Pre-filled and ready to install
What doesn’t
- Fuel economy improvement is minimal
- No accumulator in the package
8. Aeagle A/C Compressor
Aeagle targets the budget-conscious CR-V owner with a compressor that meets the basic TRSE09 specifications without the premium branding markup. The 7-groove pulley is machined to the correct 106 mm diameter, and the unit ships pre-filled with PAG 100 oil at the standard 120±10 mL charge. The clutch assembly is included, though you may need to transfer your original electrical connector depending on the pin design—some production runs of this compressor use a slightly different connector shape than the 2008 harness.
The compressor body is made from a lightweight aluminum alloy, keeping the overall weight near 16 pounds, which is close to the factory unit. Installation follows the same procedure as the OE compressor, with three mounting bolts securing it to the K24 block. The low-friction piston rings help the compressor spin freely when the clutch is disengaged, reducing the slight drag that some budget compressors impose on the serpentine belt system.
The main compromise is in the clutch coil durability. Some users have reported clutch engagement hesitation after two seasons of heavy use, typically manifesting as a delayed blow of cold air when the A/C button is pressed. The one-year warranty covers this, but the hassle of a mid-season swap is worth considering if you live in a hot climate where A/C is a daily necessity for nine months of the year.
What works
- Pre-filled with correct PAG 100 oil
- Lightweight aluminum body
- Affordable entry point
What doesn’t
- Clutch coil durability reports after two seasons
- May require connector transfer from original unit
9. TadaMark A/C Compressor
TadaMark offers the most accessible price point in this lineup, making it a viable option for owners who need a working compressor immediately and plan to sell the CR-V within a year or two. The TRSE09 core design is correct for the 2007-2014 fitment window, with the 7-groove pulley and 106 mm diameter matching the K24’s belt path. The 15.87-pound weight is within the normal range for this compressor type.
The critical thing to note is that this compressor explicitly requires transferring the original electrical connector and possibly the clutch from the old unit. That means you need to retain your old compressor until the swap is complete—if your old unit is already removed or damaged beyond salvage, you will be stuck without a working clutch. The instruction to clean the entire A/C system before installation is standard advice, but TadaMark emphasizes it heavily, suggesting that units returned with system contamination will not be covered under warranty.
The PAG 100 oil is pre-filled, but the factory charge may settle during shipping, so you should rotate the compressor shaft by hand a few times before installation to redistribute the oil inside the piston bores. The one-year warranty is the shortest in this lineup, which reflects the cost-optimized component sourcing. For a short-term fix on a vehicle with a clean A/C system, this gets the job done without breaking the budget.
What works
- Most affordable option available
- Correct TRSE09 and 7-groove pulley
- Pre-filled with PAG 100 oil
What doesn’t
- Requires connector and clutch transfer from old unit
- One-year warranty is shorter than competitors
Hardware & Specs Guide
TRSE09 Compressor Architecture
The 2008 CR-V uses the TRSE09 axial-piston design, which features a swash plate that translates rotational motion into linear piston movement. This configuration produces steady refrigerant flow without the pulsation inherent in older wobble-plate designs. The compressor displaces approximately 150 cc per revolution, matching the system’s 5.3-liter refrigerant capacity for optimal heat rejection through the condenser. The 7-groove 106 mm serpentine pulley ensures the belt runs at the correct speed to maintain proper suction pressure at the evaporator outlet.
PAG 100 Oil and System Lubrication
Polyalkylene glycol (PAG) 100 viscosity oil is the only lubricant compatible with the TRSE09’s internal seals. The system holds a total oil charge of approximately 180 mL, with 120±10 mL in the compressor sump and the remainder distributed through the accumulator, condenser, and evaporator. Using a different viscosity, such as PAG 46, will cause the shaft seal to leak within weeks. Overfilling beyond 130 mL can cause oil slugging, where liquid oil gets trapped in the piston chambers and bends the connecting rods during startup.
