Question about 2000 Volkswagen GTI

Air conditioner pump slips on serpentine belt when activated

Air conditioner pump sometimes slips for 30 seconds on serpentine belt sometimes when you turn AC on then works fine after. This is very hard on belt, it lasts only about 3000 miles as is, and one almost broke.
Installed new belts, tensioner, and even used belt grip. the engine almost stalled when the AC was turned on after I used belt grip and it still slipped. After the initial 30 second slip and squeal it operates fine. The AC has the original factory charge. A shop said the inlet and outlet pressures were perfect and it operated fine for them. They said Oh this may cost $1,800 to fix (which would replace everything for that money-which I do not have).

See if that vehicle came without A/C. If so ck for the belt availability and see if it can be put od bypassing the compressor. At the least, disconnect the compressor clutch wirin g so the A/C will not function at all. until you can manage a the cost of a pump. Good luck, Ned

Screeches on start up


This is caused by the serpentine belt slipping, and usually on the water pump pulley. Go to an auto store and buy a spray of 'belt conditioner', also called 'spray grip'. Spray it on the inside of the belt with the car running. It improves grip and gets rid of the screech. Sometimes it will need two daily applications.

Unable to crank engine over by hand. Have removed plugs, only one plug # 3 shows evidence of combustion brown color. Honda had replaced serpentine belt 1 month prior. Any suggestions?


The only thing the serpentine belt does it turn the accessories. AIt has nothing to do with the timing of the engine. However, if an accessory has frozen up, power steering pump, air conditioner, alternator, tensioner pulley, idler pulley, etc. it can sometimes prevent the engine from turning over. You can try removing the serpentin belt and then try turning the engine over by hand. with the plugs out. If it turn over easily with the belt removed than check all the accessories.

if it still does not turn over than the engine may be seized...

When stopped in drive the steering wheel vibrates a lot when the air conditioner is on .There are already new motor mounts replaced could it be the adjustment of the idle screw ?throttle plate cleaning...


The belt tensioner can cause many of these problems, sometimes the serpentine or fan belt is replaced, but the tensioner is not given much thought, a tensioner that is going out, can cause the belt to not have enough tension to keep the battery charged by slipping, when the clutch on the ac compressor cycles on and off, if the tensioner is to loose, or not tight enough can cause the compressor to vibrate, it can cause wear on other parts attached to the belt even cause pre-mature wear on other pulleys. good luck!

Is an Air Conditioner Belt the same as a serpentine belt in a 2004 chevy tahoe?


NO, your truck has 2 belts one for the A/C and one for everthing else.

Serpentine belt has some cracks


any cracked belt should be replaced. the timing belt drives the cam shaft while the serpentine drives the power steering pump, alternator, water pump, air conditioner compressor, etc. if it breaks in the middle of nowhere, car will get hot real fast and become very hard to steer as you try and find somewhere to pull over. it will also be in the night and adverse weather. so replace it now when it is convenient.
