Question about 2002 Chevrolet Tahoe

1 Answer

I have a 2002 chevy Tahoe that the AC Comp. went out. My mechanic and I replaced the comp, orifice, expansion valve and accumulator and it has worked excelent for about a week. Now the belt tensioner is starting to bang against the transmission lines. All pressures are good and we have to put the setting on low or you will freeze. Any suggestions as to the cause of the tensioner jumping so much?

I have the same problem and was told that there was a glitch in the compressors from this era> approx 50 % had this problem have changed tensioners and everything only to have same problem of transmission lines chaffing the belt until it breaks. Was told there is a kit you can buy to fix for about $400 otherwise I continue to replace belts. We did put less freaon it it to minimum pressure which did help the cause but will still viberate raiator lines in some cases.

Where is AC Expansion Valve located on a model 2000 Lincoln LS

You will not have an expansion valve, you will have an orifice tube and it should be located in the suction line going to the accumulator.

On our 2003 Tahoe there is a pump like squeak, umm, almost like bed springs when... Um, nevermind, when the ac power is on. Everything is working ok but sure is irritating. Seems to be getting louder.

If it is worse when reving the engine in park, your AC compressor is failing (common problem). The AC compressor, orifice tube, accumulator, belt tensioner and AC belt will need to be replaced and the AC system flushed before recharging.

Where is the expansion valve located? The air conditioner is blowing hot air in front and rear units. I did put two cans of fr-ion.

Is the system full of freon ?
The rear ac uses an expansion valve, and the front ac uses an orifice tube. One system can work independently of the other.

Clogged AC for BMW 118i

You have to remember, your A/C system is a sealed system. If there are contaminates in the system, where did they come from? The only moving part is the Compressor. You might be able to get by for a little while with just changing the orifice tube, or expansion valve and recharging the system. But inevitably you will need to change the compressor. Anytime you install a new compressor you will need to change the orifice tube or expansion valve and the accumulator. Dryer. You will also need to have the evaporator core and condenser flushed out. While I have a system open I also change the o-rings at all fittings. This will ensure many years of trouble free operation.

Have 2001 Tahoe. AC runs cold in front and warm in back. Repair shop says rear expansion valve plugged (metal shavings, etc.). Suggest replacing compressor. Intend to get rid of truck early next year...

no it will not fail but i suspect that you only need a recharge of gas as with two AC units you should have about 1.2 kilos of gas in this system and i think you only have about half that ?? could be wrong mind but i do think your being taken here to make up the wage bill for the month
