How to Replace an AC Compressor in a Subaru Forester

AvatarByCarl Frisch

The process of replacing an AC compressor in a Subaru Forester involves removing the existing compressor from the vehicle and installing a new one. This process can be done either with professional help or on one’s own. If done without professional help, it is important to make sure the right tools are used and that safety precautions are taken. The following steps provide an overview of the process:

1. Disconnect the negative battery cable to ensure safety while working on the vehicle.
2. Drain any remaining refrigerant from the system by attaching a manifold gauge set and opening both high and low side valves to allow the gas to escape.
3. Remove any wiring, hoses, or other components that may be attached to the compressor housing before unbolting it from its mounting bracket and carefully lifting it out of its position in the engine bay.
4. Install any new wiring or hoses that may be necessary for connecting the new compressor and ensure all connections are secure prior to bolting it into place in its mounting bracket.
5. Connect manifold gauge set to recharge system with refrigerant until desired pressure levels are reached, then close valves and remove gauge set from vehicle.
6. Reconnect negative battery cable when finished.

What is an AC Compressor?

An AC compressor is a key component of an air conditioning system in a vehicle. It is responsible for compressing and transferring the refrigerant to the condenser, which then cools the air before it enters the cabin. The compressor works by taking in low-pressure refrigerant vapor from the evaporator and compressing it into high-pressure, hot vapor. This hot vapor is then sent through to the condenser, where it cools down and turns back into a liquid before entering the evaporator again.

There are two main types of AC compressors – rotary and scroll – each with their own advantages. The rotary compressor uses a rotating motor connected to a drive belt to rotate a set of gears that compress the refrigerant vapor, while the scroll compressor uses two interleaved spiral or “scroll” shaped plates that compress the refrigerant by moving them against each other.

How to Replace an AC Compressor in a Subaru Forester

Replacing an AC compressor in a Subaru Forester requires some specialized tools, but with some patience and careful work, it can be done fairly easily. Here are some of the tools you will need:

– Socket set
– Wrenches
– Flashlight
– Screwdriver
