Hi everyone. I just joined but have been reading for a few months. I have had my 1996 Bonneville for 5 years now. I was looking for some advice. It has 160,000 miles on it and I wanted to know what should I be watching or changing to keep it going good. I know about basic stuff(oil, fluids, brakes, and gas of course ). I had to have the trans rebuilt about a year ago. what else should I be Inspecting? Thanks

Does your car have the L36 engine? Watching your coolant is #1 priority.

If you aren't supercharged that is the artlcle to know.

If you are supercharged, the lower intake gaskets are probably starting to be questionable and should be replaced either way soon.

thanks

Can you please put your car'* trim level in your signature? When dealing with mechanical issues, the fact of whether or not you have a supercharged engine changes the troubleshooting process quite a bit.

Thanks
