SOURCE: Chevy Trailblazer Engine very loud when starting

it's too early to tell. i,ve never known a light to come on because of a thermostat.you need to see what code was stored. without knowing,im just guessing. but my first thought was a plugged up catalytic converter. that explains the low power,also fuel filter.

SOURCE: High pitch winding noise on cold start up.

Sounds like a constricted IAC Idle air control valve passsage. Fairly simple to fix. Remove air filter trunking all the way to the throttle body to allow access. The IAC allows air passed the throttle when closed at idle. Just on the inside of the throttle body in front of the throttle flap there is an opening in the throttle wall. This is the air inlet to the IAC; there is an outlet similar on the other side of the throttle. Use carb cleaner and cloth to shift the grime from this tubing and get it like new. Hold the throttle flap open to get at both ends of the IAC tubing. The IAC can be detached and cleaned to a shine. Reinstall the IAC and replace all air pipe ducting. Leave for about 20 minutes to allow any cleaner residue to dry out. When you restart you might experience a bit of uneven running but this will disappear very quickly as the last of the cleaner dries out

You need to get the fault codes read to determine where the problem is that set the SES light. Autozone will scan your car at no charge. At some point you will need to get a mechanic involved to further diagnose the codes.

What is making this 08 caliber 2.0L sxt cvt have a High pitched whining sound at idle and driving?


Possible bearing in one of the drive pulleys. I have changed numerous alternators for this noise. Take the belt off and start the car. If the noise goes away you know it will be pulley related and not transmission related. If noise goes away, spin all pulleys by hand to determine the defective/noisy one

Whining noise on 2002 chevy tracker, comes and goes


Could be your alternator or a bad idler pulley. Is the transmission good? It may be the tranny or your differential whining.

I HAVE A WHINE IN THE ENGINE 4.2 CHEVY TRAILBLAZER. i THINK IT IS THE IDLER PULLEY. IS THIS AN EASY FIX ?


Yes, very simple....about 15 minutes and around $25 for the pulley.

The belt tensioner also could cause this problem, another easy fix.

Try taking the belt off, and start up the engine. Do you still hear that sound? If not, you're on the right track with the Idler Pulley. This sounds like a power steering pump starting to go out when they are bad, not a high pitched squeal.

Continued battery drain and high pitched noise when car started


Maybe the alternator is bad. A high pitched whine could mean that the alternator is not working properly.

One can test, by removing the belt to the alternator and running the engine and seeing if the whine goes away.

Have 93 Chevy G 30 Have a High pitch whine that changes with rpm


This could be anything from the pump in the transmission to the alternator bearings/bushings to the power steering pump. Could be an idler pulley bearing, but I doubt it.
Hint: If the noise is very high-pitched, check the alternator. If it is a lower, medium-high-pitch sound that changes some when you turn the wheels, check the power steering pump. If it is almost like a moan or a "Whooo" sound, that's the transmission pump.
