Accessory drive Tetris is just part of engine swapping. I fully understand the desire to keep an 8 rib blower belt. I had a dealer installed Whipple in a 1993 Indy pace truck that ate 6 rib belts on a monthly basis. In my world blower belts have teeth... I suggested the blower belt loop because it m...

Hard to picture the issue with the OEM drives, but could you simply relocate the compressor and leave the other accessories on the 6 rib belt? There are 8 rib compressors. Could you put a larger displacement compressor someplace more accessible using the supercharger belt? For instance there are 8 r...

The system will try to run at a low charge, but it goes to full stroke & sees an out of range low pressure. It is not returning oil very well at low charge either. You can add some refrigerant to stretch another month & get past the worst of the heat. But it is only guesswork. Watch the high...

No clutch on that compressor, so it is not cycling. Looks to be low on charge. Recover it & charge the correct quantity of refrigerant by weight. Electronically controlled variable displacemnt compressors are sensitive to charge levels, so topping off is a no go. Add some dye before you charge it.

Yeah Ice it is a great design from a corporate standpoint - it begins grinding itself to bits from day one, generally making it to the 50k mark still working... The scroll in the 2007 VUE wore out @55k. It would no longer cool below 2k engine rpm, and the dealer replaced it under an extended warrant...

Condensing problem. Condenser fans , air path blocked etc.

Were those pressures taken at 1500 rpm? Both cabin fans on highest speed? Doors open?

What year is this Toyota?

There is no such thig as a "scroll valve". The Scroll type compressor has 2 scroll shaped elements, one that is fixed, and a second one that orbits within the fixed part. When they wear, they touch each other & shed metal. This increases the clearance between the elements, and the pump...

System leaks slowly > Low charge causes poor performance > … The problem is a stuck control valve can mimic all sorts of other issues. That is why the FSM says "replace compressor" - because it is not cost effective to do otherwise for a line mechanic. You can't expect a compressor to &quo...

When the control valve fails nothing gets "shredded" - there will be no evidence in the oil.

I would question the inability to charge it properly first. Are you using cans or a tank?

Why was it recovered in the first place? How much refrigerant was recovered?

A 14 year old scroll compressor that is leaking oil... One choice A/C or NO A/C. The compressor is shedding metal in to the condenser. It is also losing lubricant. The fix is a new compressor, a new condenser and a new dryer. As a Vue owner I can tell you the job is not a driveway job. The service m...
