1988 Subaru Conversion A/C removal
Posted 10 March 2004 - 02:20 PM
Cars that came out of the factory without A/C was there just one belt?
If so can someone post a picture of the setup?
I looked at the junk yard but didn't see any without A/C so a picture would help. If it is a one belt system I think I just might put new pullys on my car to loose the extra weight of the double pullys I now have. I'd also like to see how they mounted the alt. It looks dumb hanging way outboard without the A/C compressor. I made a bracket to support the mount that bolted to the A/C compressor. I got to find a car without A/C and rip off that mount, picture would be helpful.
In place of a picture a link to a shop manual will be just as useful.
-When I'm done with this conversion I'll write up a do's and don't

In this view:
you can see that the non-A/C setup used a double pulley on the alternator. If you run only one belt, and keep the belt-driven radiator fan, then you risk having the belt slip on the water pump pulley. Such slippage can easily lead to overheating.
Personally, I'm not overly pleased with the setup I have because it uses the alternator to tension both belts at the same time. It is therefore impossible to get them equally tensioned.
Another tip for A/C removal:
Pull the evaporator core out from under your dash. You can either replace it with the piece used in non-A/C cars, or you can just remove it from its housing, plug off the holes that the lines ran through, and re-install just the housing.
When I did this, I found that my evaporator core was largely plugged up with dirt. Eliminating it has increased the airflow through my heater dramatically. I no longer freeze in the winter, and actually get enough airflow to help cool me in the summer.

I also found out in the owners manual that two different types of A/C comprssors were used. One mounted inboard of the alternator, the other outboard. Interesting.
I've got an update on my 3At - 5SPD D/R conversion....
BTW that is one clean engine, I take it you just rebuilt it? Sweet.

Do you just plug the hydrolic oil ports or do you swap out the steering gear?

Steering a non-powered PS car is much harder than steering a non-PS car.

The valve covers gaskets were hard as rock and crumbled as I removed them. The ventilation hoses to the heads are also in need of replacement. Is there an off the shelf substitute? Or do I have to go to a Subaru dealer?
Also, did the non-A/C cars come with a two belt alternator pully instead of a one belt?

From what I've seen, the non-PS EA82 cars are rare. I think PS was standard on most GL models, and I see it on alot of DLs too.
If you're talking about the PCV hoses, you should be able to find suitable replacements at any parts store.
