1988 245 AC Problems

Hello,

Anybody out there that could answer a couple ac questions about my wagon.

I just finished replacing all of the ac components in my ac system, with the exception of the evaporator.

Took it to a shop, had them pull a vacuum and make sure there were no leaks. That was successful, so the system was charged.

The questions I have are the following :

1.) Does the thermal expansion device next to the evaporator need to be reinsulateed with the black sticky tape or just leave it bare?

2.) I hear a quick chirp every time I turn on the ac, and it is coming from the compressor. Compressor is brand new. Belt appears to be good and snug. The one thing I did notice with the compressor, is that it appears to be cocked at a slight angle away from the engine. Does this seem right?

Some time, the chirp coming from the compressor, is a squeal for a second or two.

Any advice on this would be greatly appreciated.

Scott

Well, creating a vacuum does not prove there are no leaks...even when vacuum holds for 1/2 hour.

Whatever OEM used for insulation, is just fine...their engineers know what's best.

Compressor chirp is either AC clutch or belt noise
