This is actually an easy swap out. Remove the electrical connection, remove the retaining bolt and pull out old one. I believe the sensor is located in the front passenger side of the engine on this particular model.

This one is easy. The clutch fan is not disengaging. Mine does the same thing after it has idled a while but then will release (wind noise stops) after getting up to speed.

SOURCE: 2002 Chevy Trailblazer, brake lights won't go off

check your brake light switch. It may be stuck on. it is under the dash. a button on the switch touches the brake lever to activate the brake lights.

It sounds like the engine has a bad vacuum leak, they are very problematic for a leaking intake gasket. This usually would be accompanied with coolant loss, but not always. Other causes are loose air plentum snorkel (if air filter recently replaced) or a leaking vacuum hose. It could also be a sign of a computer problem starting. It would be best to have a technician or parts retailer scan it for you to narrow the problem down. The clunk noise maybe unrelated or possibly engine noise(like an intake issue), check the oil and coolant levels first.

Engine has a whirring noise, like a dry bearing on a pulley.assuming its a pulley because it gets louder when revving engine.


The noise u hear is most likely coming from a defective power steering pump or accessory belt idler pulley, to make sure use a 1/2" wooden dowel or old broom stick and hold it against the area where u hear the noise to isolate the exact location.

Engine makes loud knocking noise that seems to be coming from the very top of the engine. I should note that this car has 175000 miles on it


Knocking noises from the overhead cam may be making the noise in question. Maybe a bad bearing on the camshaft or a spun cam.

175,000 mi. is a lot of miles for an engine, it may have been over revved at some point, or suffered from oil starvation or dirty oil with a prior owner.

I have a 1998 Cavalier (147,000 miles) that has made a ticking noise when I start it. However, revving the engine will quiet the noise before driving. Recently, it began making a extremely loud grinding...


unfortunately at 140,000 miles much like humans parts start to wear... now you can try to flush the oil system...I DON"T RECOMMEND IT.... I have seen engines tear apart from engine oil flushes.... drain refill the oil/filter with new oil and an additive may help, or pin down the noise to what lifter is going south and have it replaced... may end up being a very expensive repair depending on what they find when they open the engine up with high mileage...or just continue driving it untill it completely wipes out... I do belive its a hydraulic lifter that is not pumping up causing the tick and if so they usually last a long long time noisey.
