AC Condensor

[gtpchris]

Hello,

Does anyone know the AC condensor type in a 1997 GTP? Is it parrallel, serpentine or round-tube?

I have a failed AC compressor, and just about to replace it with a new one (along with o-tube and accumulator etc...).

I think the factory condensor is the parralel type. I've read that parrallel type condensors are NOT capable of being flushed.

Everything I hear says it's absolutely imperative to flush the AC lines, evaporator, and condensor.

If all the above logic is true, then all failed compressors automatically require a new condensor?

Also, how many ounces of PAG oil do I need for the 3.8 vin 1?

What are the optimal 1997 GTP gage pressures for hi low side (engine off, & engine on-ac at max)
The average for most ac systems is 125 (engine off) & 25 psi low 250 psi high (engine on/ac max).

Thank you!

-Chris

Wow...zero responses. I had better luck at the bar last night!

If anyone needs to know, I've answered some of this trivia.

The 3.8 GP's use a total of 8 oz of (150) PAG oil. If you replace any part of your AC system it's wise to flush everything out and put a full 8 oz of fresh oil (this stuff absorbs moisture so pop the can and use it quick). Do NOT flush compressors, o-tubes, accumulators or mufflers!

3.8's use exactly 2.5 12 oz cans (30 oz) of R134a.

Also, the final pressure readings you want would depend on the ambient temp on the day you perform the job.

If it were 75 degrees outside, then optimal Low pressure readings should be 40 psi +/-5, and hi of 160 +/-10 psi.

Low readings wont change as much as high for ambient temp changes.

For instance if you did the job on an 85 degree day, then low pressure should read 50 psi +/-5 and high of 238 +/-10!

If anyone out there is a GP condensor type expert, I'd love to know....!

guess there's no a/c techs on this! good info man! saved me from having to look this up when i replace my blown condensor. rockauto has them cheapcheap!
