Will the A/C compressor assembly from the 4.3 fit on the 5.7 or similar Vortec engine? I'm getting my assembly replaced and I want to know if it will cross over to the bigger engine.
I am sure it will fit but is it the right one. I have found 4 different compressors on the 4.3 vans alone. Physically it will bolt on. But electrical conectors may be different. Manifold in the back has two styles. And there are 2 completely different compressors.
So in a nutshell, if it just happens to be the same one. Compressor that is.
Compressor clutch plug there are 2 types.
Aluminum and cast cases interchange. I have aluminum now and it came with a cast.
Manifold where the hoses bolt into the rear of the compressor. 2 Types Look the same but one the hoses are offset and not in the same plane.
Some have high pressure switch on the rear of the compressors and others don't.
Last is most obvious the passenger side compressor which is donut shaped. I don't know if it has variations I never had to deal with one Yet, Key word yet.
I only have front A/C. So the compressor should work then. That makes the price of the repair more bareable.
