You are in the Pontiac Bonneville
What is this discussion about?
Pontiac Bonneville, Sedan

I bought an after market mask from Lebra for my 2000 Pontiac Bonneville In Feb 2001. I only had it for a month and moisture and heat from the mask formed a cloudy stain in the paint on my hood! What ever you do, only get a mask that your dealership recommends. This way they can be held responsible if anything occurs under they mask while you are using it. I took the car to my local dealership and they wouldn't touch it and Lebra says I have to first take it to an auto shop to have heat lamps put on it to try to remove the stain and I will have to be reimbursed for that! I've used a Lebra mask on my 92 Bonneville for weeks at a time with no ill effects. My wife uses a GM mask for her 98 Grand Prix and no problem there either, so I would just be careful.

I once had a rubbing/clicking type noise coming from the front of my '94 Bonneville on sharp right turns. I stopped the car in that position to find the left tire hitting a piece of the fender that came loose.

Thanks for the tip about the front-end mask. Sorry to hear about the damage to your Bonnie. I have been wanting to get one for my 2000 SSEi and not all the mask manufacturers seem to have one yet for this model. I was thinking of just getting the GM Accessories one even though I'm not sure it is of the best quality or value.
The number with the "U" (for "upper", "L" for lower if two-tone) is the paint code. What color this actually is you'll have to look in the Helm service manual or just ask the service or parts department at a GM dealer.

I'm also considering what to do to protect the front of my 2000 SE. It already has 23K on it since I bought it used and you can really see the chips on the facia and even the hood. I do a lot of highway driving and of course here in the northeast we have road salt and sand all over the roads. Not sure what I'll do.

Hello, thanks everybody for the help with the color code. I have another problem now that seemed to me simple at first. After the engine gets warm I can hear squeaky noise from the engine. It comes from the belt and I was told by few persons that it is faulty water pump. Two days ago, the water pump was changed for the remanufactured one (NAPA). However, the behavior and the noise stayed the same. I tried to listen to the noise with the long paper pipe in order to allocate the source of the noise. It seems to me that the noise is coming from the bottom rear wheel that is moved by the belt also. I do not know what is the function of this wheel. My question is whether I could be right about the source of the noise. Or do you think that it has to be the water pump and the remanufactured one was faulty?

dbaca, if the noise is pretty much the same after changing the water pump then either the serpentine belt or one of the belt tensioner pulleys is probably at fault. A stethescope with a 12" probe (or equivalent) will isolate it pretty quickly. Obviously, take care around rotating components.

alcan, thank you for your help. The serpentine belt is brand new, so it must be one of pulleys or the water pump. The water pump is just a little bit wobbling; therefore, it occurred to me that the remanufactured water pump could be faulty.
#271 of 2268 the noise comes from the transmission

I wrote the message 268 thinking that my problem is the water pump. However, starting the engine without the serpentine belt showed that the noise is approximately coming from the space between the engine and the transmission. The auto-mechanic took off the bottom cover of this space, but nothing bad was found. I found out that the frequency of squeaking does not change along with the engine repetitions. I have been driving with this noise 6000 miles and it is still the same. My Bonneville is SE type, has 91000 miles on and is from the year 1995. Does somebody have any idea what can be the source of the noise?
#272 of 2268 again the noise

The noise turned out to be caused by the engine. People from GM looked at the car and they found out that there is too much vacuum in the engine. When they opened the gap for filling engine oil, the noise stopped. They suspected the PCV valve, but its change did not help. Any ideas?

That really would suck!
