Re: Mini compressor/less CID output?

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...

Re: Mini compressor/less CID output?

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...

Re: 2007 Audi A4

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...

Re: 2007 Audi A4

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.

Re: AC compressor leaking - Can I patch 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...

Re: Toyota Sequoia poor AC performance

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?

Re: AC compressor leaking - Can I patch it?

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...

Re: 2006 Nissan 350z Pressures Equalized While Running

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?

Re: AC compressor leaking - Can I patch it?

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...
