Replacing the AC compressor on a 2008 CR-V costs $739–$1,841 and requires refrigerant recovery, belt removal, and bottom access to the unit.
You can expect a 2008 Honda CRV AC compressor replacement to cost $739–$1,841, with labor running $256–$376 and parts $483–$1,465. The job requires recovering the refrigerant, removing the serpentine belt, and accessing the compressor from underneath the vehicle — it’s not visible from the top. This guide covers the right parts, the cost breakdown, and the step-by-step procedure so you know exactly what the job involves.
What Parts and Specifications Fit a 2008 CR-V AC Compressor?
The 2008 CR-V uses the 2.4L engine, and the AC compressor is shared across all 2007–2011 models (LX, EX, and EX-L trims, both 2WD and 4WD). The common replacement part numbers are CO 4920AC and DEN 4717056 (OE Manufacturer). New compressors typically come pre-charged with about 3 oz of PAG 46 oil and include two O-rings for the suction and discharge lines.
Key system specs: the refrigerant charge is 0.49 kg (roughly 17.3 oz) of R-134a, and the correct compressor oil is PAG 46 viscosity. When the system is open, replacing the dryer/accumulator is recommended — it adds roughly $128 in parts. The expansion valve only needs replacement if metal shavings from a failed compressor are present in the system.

2008 CR-V AC Compressor Replacement Cost Breakdown
According to RepairPal’s cost estimate for this job, the total ranges from $739 to $1,841 depending on your location and shop rates. Here’s how it breaks down:
| Item | Estimated Cost |
|---|---|
| Total job (parts + labor) | $739 – $1,841 |
| Labor | $256 – $376 |
| Compressor and related parts | $483 – $1,465 |
| Condenser assembly (if needed) | ~$284 |
| Suction hose (if needed) | ~$137 |
| Dryer/accumulator (recommended) | ~$128 |
These figures exclude taxes and shop fees. If you’re doing the job yourself, parts-only cost for a quality aftermarket compressor runs $200–$400, with OEM parts costing more.
How to Replace the AC Compressor on a 2008 CR-V
This job requires moderate mechanical experience and the right tools: a serpentine belt tool, 10 mm, 12 mm, and 14 mm wrenches, and a clip tool for the power steering reservoir. The compressor is only accessible from underneath — never try to reach it from the top. Below is the condensed procedure based on the technical documentation.
- Recover the refrigerant. Use proper recovery equipment to empty the system. Venting refrigerant to the atmosphere is illegal and unsafe.
- Remove the front splash shield. Take off the plastic cover under the bumper by removing the push rivets on both sides. This gives you access to the compressor from below.
- Remove the power steering reservoir. Pull the tab or clip and lift the reservoir out of its bracket to reveal the belt tensioner.
- Remove the serpentine belt. Loosen the 14 mm tensioner bolt and slip the belt off. Disconnect the electrical connector and remove the 10 mm bolt on the AC line, then the 10 mm bolt on the upper line.
- Unbolt the old compressor. Remove the four 12 mm bolts at the top. Rotate the compressor so the pulley faces the passenger side, then lift it out from underneath.
- Install the new compressor. Apply fresh PAG 46 oil to the O-rings — never use brake cleaner on them. Rotate the new compressor into position and secure all four 12 mm bolts to 16 ft-lbs. Tighten the AC line nut to 7.2 ft-lbs.
- Reassemble and recharge. Reinstall the belt, power steering reservoir, and splash shield. Vacuum the system for 15–30 minutes, then recharge with exactly 0.49 kg of R-134a. Avoid using pre-charged cans from parts stores — they can introduce air into the system.
Common mistakes: using the wrong oil, reusing old O-rings, and removing the plastic plugs on the new compressor too fast (cover ports with a rag to prevent oil spray). If the compressor failed internally and left metal shavings, flush the system and replace the expansion valve.
FAQs
How long does it take to replace the AC compressor on a 2008 CR-V?
A professional shop typically finishes in 2–4 hours. A first-time DIY mechanic should budget a full afternoon, including time for vacuuming and recharging the system. The extra time is mostly spent on access work — removing the splash shield and power steering reservoir adds steps that aren’t obvious at first glance.
Do I need to replace the dryer/accumulator too?
Yes, it’s strongly recommended whenever the AC system is opened for compressor replacement. The dryer absorbs moisture and contaminants; a fresh one ensures the system stays dry and corrosion-free. Expect to add roughly $128 in parts cost for this component.
Can I replace just the AC clutch instead of the whole compressor?
Only if the compressor itself is still functioning and the clutch is the sole failure point. On the 2008 CR-V, the compressor often fails internally (seal leaks or bearing noise), making a clutch-only fix pointless. Diagnose carefully — if the compressor turns freely and holds pressure, a clutch replacement may work.
