Hello!

New Expert here!

Brown Jeff has given you great detail on how to remove and replace the AC compressor.

The AC compressor will need to come out from underneath the vehicle. You may need ot remove a skip plate or a engine cover underneath the motor to gain access to the AC compressor.

skip plates are off,there is still no acess to tho compressor mount,also there is not enough room to drop the compressor down without removeing the oil filter ,oil pump and mucho wireingis inthe way. Can the compressor come through the front if the fan shroud and raideator are removed:?
Expert:  Amedee replied 4 years ago.
I suppose it would be worth a try. Its either that or remove the the power steering pump above it and remove it from the top.

YUP! THats one way to do it.

It only calls for about 3.0 hours labor to replace the compressor according to my labor guide. But there are several different ways you could go about replacing it.

Anyway, glad to hear that it is done!
