I have a 89 Aero 3.0 it had R-12 in it.

I would like to change it out with a system out of a 94-96 that had the R-134 system.

The question is does the Engine Turn the A/C Compressor in the same Direction on the 94-96 as it does on the 89.

Thanks

 

I would say yes. Both my 87 and 97 turn the same direction. As far as I know all of the 3.0 engines had the compressor in the same place. Can't say about the 4.0.

Why do you want to do this? Is your present system working?

 

i was wondering this too.what differances are there between the r12 aeros and the r134a areos?can i just vacuum out the system,change the fittings and fill up with 134a?

 

Because R134 will leak through the hoses used on r12 systems.
Better to get all the Hoses & such off a Van that came out with the r134 system

 

I have R134a in my 87 that has an R12 dealer installed aftermarket system where most of the connections are just hoses slid over metal tubes and held on with worm clamps. But it cools great. With ambient temps in the 90s, exit air temp will be around 40 degrees. It does leak some. In the last ten months less than a half pound. I'll live with that.

zenish, no you have to at least blow out the lines, condenser and evaporator with compressed air as best you can, add the correct oil, and replace the dryer.

 

Not just blow out the lines, but clean them out with something that's compatible with the fluid you will be using. EG, the R12 system will have mineral oil as lubricant, which is not compatible with most of the lubes used in R134a systems. So first you blow it out, then you can pump some mineral spirits through it to clean out the lingering oil. Do this a couple times and blow it out again. Then it should be safe to install a non-compatible lube.

As far as the direction of rotation, I think they all turn the same way; clockwise when viewed from the front. The only thing that changes direction is the water pump, between v-belts and serpentine belts.
