Question:
I've heard everything except the actual cause. When I start my car when it's cool outside, the car makes a lous screeching noise when I accelerate. I usually let it run to warm up for a while.
Should America bring back the AMC Pacer and Gremlin?
When I do accelerate and the noise starts it's very loud and seems to be around the radiator. It usually slowly dissappears as the thermostat raises to warmer temps.
my dome light in my 98 honda civic will noy come on when i open the door any suggestions?
It's a 1989, and most of the time I'm told by mechanics "hey man, it's old it's going to make noise." No kidding.
Is there going to be a new Mercedes Benz SL class in 2008 or 2009?
What is the actual reason for this noise and any quick fix-it suggestions?
thanks!

Our cars have self-tensioning belts. Once a new belt is installed the tension is set.Is the Hyundai Tiburon a reliable car?
Either the belt has become so stretched that the tensioner can no longer keep it tight enough.
Or your tensioner is getting bad.
While looking at the front of the engine, just to the right of the block and left of the powersteering fluid can, look down and your should see a small triangle resting on a slit. the front point of the triangle should ride just above a line that is thin to one end and thick on the other. The thick side is proper tension. If the pointer is off more towards the middle or the thin side then the belt needs to be replaced.

Also ask around for another mechanic who specializes in Mercedes Benzs. If my favorite MB tech told me that was normal I would have his head on a platter.

I have a 2001 grand am that is having back end noises?
Sounds like a belt. Temperatures cause things to expand and contract. Screeching is caused by belts slipping or rubbing on something. I have a 1987 Mercedes 300e and it doesn't make a noise.. and I've had cars that were more than 20 years old that were well maintained and smooth. The mechanic who told you that is a fool. Either have the offending belt adjusted or replaced. If you don't have it repaired, the belt could break, or it could wear other parts causing more damage. I have also seen improperly fitted belts rub on nearby bolts causing them to wriggle loose and fall out... make sure you have the problem attended to.Where can I find a window kit for a 2003 Jeep Wranger Sport that fits on the factory soft top?
there are two reasons why with the screeching noiseone is the tension of the fan belt is not well adjusted,it cannot be too tight or too loose,the sound is cause by loose fan belt,the right method is to adjust at the tension bearing and at the longest side,when you press down,there should be a half an inch allowance,do not tighten it too tight because it will stress the fan belt,the second reason is the tension bearing needs replacment,bearing is worn and without lubricant,create noise when cold,good luck with your driving
