Question about 2004 Chevrolet TrailBlazer

1 Answer

My 2004 Chevy Trailblazer is making a bizaar noise when I start it up. It's starts as a high pitch squeal then drops to a lower pitch squeal then ends in kind of a grind. Thought it was a slipping belt but there's only one belt and it's fine. It runs fine and the noise dies away after the engine settles. It only makes the noise on start up. If you cut off the engine before it settles down - the noise continues, so it doesn't stop with the engine. Seems to be coming from inside the engine itself.

Hi Eabyrd05.
It's possible that you have a Starter or Flywheel/Flex-plate issue. Your starter Bendix may not be completely disengaging from the flywheel like it should. I would take it to a mechanic that you trust and have them pull the starter and look at both the Flywheel/Flex-plate, Starter Bendix and solenoid. Hope this helps.

If it is making a noise in the belt area, have them check the water pump. These get loose water pump bearings that cause belt noise.

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.

Noise from engine


Check your belt. Belts will whine when they're worn, cracked or glazed. I hope this was helpful. It's not normal. Take care and God bless.
