[FONT='Verdana','sans-serif']This only happens when the car is sitting over night, a cold start i suppose it starts with a valve tingling sound that appears to be coming from the belts, very whining loud sound that maybe even the supercharger but I can really pinpoint due to tight engine compartment. This only happens after a cold start and last for about 5 minutes until the engine warms up. I'm in Miami, Florida so we can't blame the cold. [FONT='Verdana','sans-serif']I’m sometimes ashamed to turn on the car because of this sound that makes it feel like a 1974 Ford Pinto and not a 2005 practically brand new car. 2005 MCS, no mods![/FONT][/FONT]

 

Is it a squeal or a whine?

 

more of a squeal.

 

talk to your dealer about it?

 

Ahh yes the dealer, With all do respect, is'nt the dealer why we are here in the first place, cause they don't know what the hell is going on. I did try to communicate and they mentioned something with the cooling fan? I personally think it's the belts but they could have a legitimate call. I'm trying to get the most information as possible with other Maniacs that have had this symptom arise so i can print it out and have a legitimate case with the dealer. Thanks again for your 2 cents , I really appreciate your response.

 

If it might be a "whine" your BPV could be bad also.

 

If it's a squeal, then its a loose belt. A loose belt can be due to age or the tensioning pulley has gone bad. If the tensioner is bad, you'll need to replace the belt as well, since the slippage (source of squeal) has ruined the belt. The slippage will occur primarily when the belt is cold. Once it warms up, it will maintain enough friction to avoid slippage.
