Remove and Replace Air Conditioning ? 7

[RWF7437]

Is it possible to remove the air conditioning components from a 1999 Toyota RAV4 and replace them later if necessary to use the vehicle for a trade in ? How practical and or expensive might this be ? Would better gas mileage be achieved by doing this

You have to run the A/C every week(5 minutes) or so or it will fail anyway!

Keith, I agree, on principal. I always run my vehicles AC at least once a week for a few minutes in the very short "winters" we have here in Socal...don't really have a choice with my wife's Lincoln the AC is integrated with the vent/heat system and there is no way to turn it off. However, my old motorhome (BBC w/GM AC) was in storage for over seven years and when I finally fired it up and turned on the AC I was totally shocked to find it worked to OE specs!!! Fancy that. I guess the exception does make the rule.

I seem to recall that the issue with needing to operate the AC on occasion is that the oil tends to migrate to where the heat is. That is; liquid freon carries oil but not the gas, the liquid freon migrates towards the heat where it turns to gas to condense to liquid again where it's cold, the end effect slowly moves oil towards the warmer part of the system. For a car in winter, the oil moves to the evaporator since it's usually in the hot-air path of the heater.

Evelrod - for you RV in storage, probably all of the system was at the same temperature so the oil remained distributed throughout the system. Gravity probably pulled the oil to the nearby lowest point, so your compressor seals still had oil around. Just an guess.

I had a car sit unused for 5 years. Rebuilt the engine, started up, the ac still worked???
