190E squealing
My 190E has a nasty squeal whenever the car is running. I originally thought it was the belt tensioner pulley as it had bad bearings but surprisingly it did not fix the noise. I am almost certain the noise is concentrated right above the water pump. The water pump was replaced on it almost a year ago, however the MB brand coolant was not used to refill the system. Could not having used the proper coolant caused the water pump to make noise? Other than the noise, the engine runs at normal operating temperature.

If I remember correctly you have an idler pulley up there somewhere. Check it to see if it has gone bad.

Personally, I'd check all of the pulleys for bearing wear and alignment. Although it's not likely, don't forget to check your harmonic balancer.

Mine had a nasty bird chirping noise weeks ago! I removed the valve cover to find that it was the plastic portion of the timing chain tensioner had worn and come off the metal part of the tensioner arm! Causing the chain to ride on the metal instead of the plastic! Causing metal on metal squealing noise.

Been there, done that
My squealing was the belt. A quick check is to pour some water on it while its running, it should stop for a few seconds until it dries out. A cheep fix is to buy some belt dressing. A permanent fix is to replace the belt.

Glad you found it.. ![]() ![]() DRY belt only. If it's making a noise you may have a pulley siezing or a leak from your p/s pump. ___________________________________________________________

I ran the engine with the belt off and no squeal, which limits it to belt driven stuff. I can pretty much rule out power steering, a/c and tensioner pulley as they are far enough away from the approximate source of the squealing. But like I said earlier I am almost 100% sure the source of the sound is directed dead center above the water pump. If in fact it is the water pump making the noise, does it mean it is bad and may go out at any time? (pump is only 1 year old)
A water pump is only $7 at the local pullapart so I will get one just in case. In the mean time I'll try the easy stuff like pouring water on the belt..
