Depends, these trucks had problems with this, the noise you here is the electric air pump, it can be a little noisey, it should sound like a smooth jet engine bad as it starts going bad it gets a little louder but can still last a while (ayear or two), when it goes bad the engine light will come on, if its not too loud a wouldnt worry about it, even a new one will be heard, maybe not as loud but there noisey, it runs on start ups for a few sec -20 -30) hope this helps. good luck.

Why does my 2005 chevy trailblazer make chirping noise when I first start it inthe morning but goes away when vehicle warms up


Usually the noise is a belt. The surface of the belt changes as it warms up.

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.

05 TrailBlazer 57,000 miles 4.2 6 cyl, bad vibration at cold startup, in idle and in drive, in reverse, smooth. Summer mornings just very slight. I live in central GA. My brother also has a TrailBlazer ...


WHEN YOU SAY THAT IT GOES AWAY IF YOU PUT IT IN REVERSE THE THERE HAS TO BE A MOUNT OR SOMETHING HITTING ON THE LEFT SIDE PUT IT ON A LIFT AND TAKE A BIG BAR AND MOVE THE MOTOR UP ON THE LEFT SIDE AND SEE IF THAT CHANGES THE FEEL CLEAN OUT THE THROTTLE PLATES AND SEE IF THAT TAKES CARE OF THE HESITATION

Ticking Noise at Startup


Possibly a leaking hydraulic lifter. They can leak down while engine isn't running and then make a ticking noise for a while on startup. If it takes 10-15 minutes to go away, it is more likely to be a loose tappet which needs adjusting.
