Hi everyone, My 03 str engine sqeaks for a few minutes when I start it. Whats that about?

 

That could be a number of things having to do with belts and pullys. First you need to check your belts, there are 2 of them. Check for cracks, if cracked then replace, if not check your pullys .take the belt loose and feel if makes noise and, or is not smooth then you will need to replace. You should find your ploblem prety easy and if all fails. WD40... Lol

 

My 2005 STR had the exact same symptoms. There is a TSB out on it and it requires complete replacement of several pulleys and tensioners. They replaced the following on my car:
Belt Noise Service Fix:

C2C37064 Pulley-Idle
C2C37063 Belt-Drive
C2C37057 Tensioner-Drive
C2S46862 Pulley-Idle
C2C37055 Belt-Drive
C2C37056 Bracket-Idler MT
Also listed is part C2C37055 with no description.
This was all no charge under warranty. It completely fixed the problem. I really thought the noise was very minor and almost did not bring it up!

They did the same to mine but now I have a slight coolant drip on to the belts after shutdown and I get squealing at start up. I'm going to dig in myself and solve it as I have NEVER had any luck with the dealer finding coolant leaks and even causing them when certain work was done.

 

Thanks everybody for your help, Dis anybody do any pulley upgrades or ecu and if did what gains did you get
