2002 bonneville coolant leak

SOURCE: Thermostat on 2002 Chevy Impala

the best thing to get is the Haynes manual for your car at advanced auto or autozone or somewhere like that and the book will tell you how to take everything apart and put it back. i think the manual is about $16.00

SOURCE: Leaks oil looks like from valve cover

You have to remove the spark plugs cables and remove the four nuts that you see when the cables are removed.

When the four nuts are removed, simply raise the valuve cover. When replacing the gasket, make sure you get the gromets as well. Those sometimes get worn or crack since they are more exposed than the value cover gasket. Make sure that you clean the cover from oil and replace the gasket with no use of silicon.

Good Luck.

i don't know that vehicle very well... but there are usually bolts/screws that hold them in place. 4 to 6 of them per cover. sometimes the spark plug holes have giant nuts that hold the cover in place.

He must have meant the intake manifold gasket. That is a complex job, but can be done if you have basic knowledge of mechanics and a few hand tools. Best advice is to get a haynes repair manual from an auto parts store as it will have step by step instructions and photos. Good luck. Dont forget to rate.
