Honda Pilot Compressor

BigWave on Sun June 28, 2015 1:04 PM User is offline

Year: 2004
Make: Honda
Model: Pilot
Engine Size: 3.5L
Refrigerant Type: 134
Country of Origin: United States

My car is now at 12 years/150K Miles. A/C blows cold initially, then seems intermittent. Tried a cheap fix by replacing the relays. Didn't seem to help much.
Duct temp did go from a low in the 60s to a low in the 50s, but outside temp seemed a little cooler when I tested.

This seems very similar to my 2005 Accord (less miles) that I had issues with a couple of years ago. Clutch gap was wide, and when I adjusted, the clutch burned up (at least the connector). Because of parts availability, it was cheaper to get an entire compressor assembly (including clutch), then just replacing the clutch on a used compressor.

I intend to do a few checks to confirm the clutch is engaging when cool and then not when warm. If so, looks to be the best route again for an entire assembly. I plan to keep the cars for a while, so the investment is good.

It has been a while, so I wanted to confirm my steps. Obviously pull and install the new compressor. I'll order the new one from A/C Kits.

What oil and how much do I need to add to/for the compressor? Does the compressor come filled with oil? If so should I drain it and refill?
I'll install new o-rings on the compressor lines - anywhere else I should do this as preventative?
Any other items to replace at the same time? I can't find a receiver/drier in parts, but there is a desiccant bag? Any other common fail items I should knock out while the system is uncharged?
What final pressures should I aim for when refilling the R134? I'll use the volume capacity as a guide, but want to get it spot on.

Drain and refill is my suggestion.

Drier housing is mounted on the condenser. So desiccant bag is all you need for replacement.

Always charge a system to the OEM specs.
