Re: Big truck a/c help

High side pressures have a lot more meaning with an ambient temperature to relate them to.

Have you checked the oil level in the York?

Re: R134a cooling - acceptable or is there a problem?

Soak the condenser with water. See where the pressure goes.

It would not be the first time a shop added extra oil.

You used a GM part number for the condenser - is this a GM part or aftermarket?

Re: R134a cooling - acceptable or is there a problem?

Your high side pressures indicate a problem. Should not be tagging the HPCO at 93f Either a condenser airflow problem, or way too much oil in the system. The F body fans may be part of the problem. How much water did you hit the condenser with? If you soaked it good the high side should drop like a ...

Re: Looking for Help with my AC

The clutch gap gets wider as things wear. Adjusting it is not difficult if you can get at the end of the compressor. The gap should be .016 to .032 according to the factory. Setting it on the low side, even as small as .010 is fine as long as it does not drag when off. The adjustment is done by remo...

Re: 2006 Ford Expy not cooling well

Looks more like a condensor airflow problem. A 2006 has a thermo fan clutch. They wear out. It takes a special pair of wrenches to swap one - most auto parts stores rent or loan the tools. While you are doing that, clean the condenser and radiator air path - use a garden hose so you don't bend the f...

Re: Ford E350 Econoline Front AC not working withour Rear AC on

Does the front system cool when the rear is turned on? Or is the rear system the only one that cools?

Sounds like you have had the vehicle for a while - did it work properly at one time?

This does not sound like a bad compressor yet. We need a little more info.

Re: 99 Maxima static pressure too high on low side

You can't just add 1.5 times the charge based on a pressure reading. It sounds like a measurement issue. Hoses on wrong manifold nipples Schrader valve not depressed by charging hose hose check valve issue 225 static in the system would mean the system was at around 140f. Possible, but unlikely if y...

Re: Oil in an RV engine AC compressor

Virtually every full size pickup, G van, Suburban etc. in 1999 used 8 ounces of oil in the system.

2.5 ounces is for a compressor replacement only, not for a clean & dry system.

Re: Mercedes 240D freon Capacity

The York compressor has an oil sump. It should be drained. If you need to flush it, use oil to flush. Use the same oil you intend to use in the system. Flushing procedure http://www.autoacforum.com/messageview.cfm?catid=20&threadid=12050 To check the oil in York, you need a dipstick. Easy to mak...

Re: Nitrogen pressure testing questions
