+2 MPG How-to Guide with this kit…

[g8mfzj80]

The AC eliminator kit , original AC compressor started to give me problems at ~154k so I pulled it out at 155K since it was only putting out about half the pressure needed to make it cold.

After two fill up’s I ended up needing about +2MPG gain, but much rather have the AC so I’m putting the OEM one back in later today I that I had rebuilt for ~70. Kind of surpised that one less belt could make a difference, maybe I was just lucky or it was that and my O2 sensor replacment that I did the same day.

Thought about buying a new Toyota OEM, 3rd party new or even reman but decided to have the stock one rebuilt. The clutch is still fine and I have a friend who works in the residential cooling and heating field with all the needed stuff to help with the evac and refill which goes pretty quick with the small amount the system takes. Also replaced the AC receiver/drier.

While we are on the subject let me ask a question. I have noticed that my 80s A/C does not exactly blow ice cold. Is it possible that it needs to be serviced or replaced? I wonder if this is expensive like if I took it to SDTrux of course? Anyone have a ball park or tip/advice? Im completely naive about this chit mang.

buy at Autozone etc a filler kit, basically just a hose and connector, a gauge and and a valve. About $30. No need to get refrigerant cans yet. Just plug it on (quick disconnect) and read the pressure. That will tell you right away if it needs filling. (Or do the bubble check but vaguer.) If it needs filling, buy a can ($10) and put it in with the new gizmo you just got. Done.

I need to educate myself a little I guess, thats my responsibility. Maybe the guys at the auto shop could give me a little direction for the info though, thanks!

Your 94 may have an r12 system, take a look for the tag under the hood, it will say r12 or r134, if its 134 you can just add some and probibly get back to normal, I would have someone leak test it after adding a little..... just to make sure you arnt wasting your time by it leaking right back out.

that is true, if it's Freon (R12) it would be more than $10 and there may not be small cans and cheap gauges readily available... Plus you don't want to have it go into the atmosphere if it is still leaking... Should be emptied and fixed. Or you could convert it to 134. If it's leaking would be a good time to do that.

So did you take the compressor to someone to rebuild or did you do it yourself? After doing a leak test it was discovered that the main seal on my compressor leaks. I am debating a new one or rebuilding. Not even sure it can be rebuilt. I also plan to do the expansion valve and shorter dryer at the same time.
