Hey everyone, new guy here.

I have some questions on general maintenance, since I've been unable to find any kind of maintenance manual anywhere;

I'll be buying a 2000 Bonneville this week. It'* clean, pretty and a great deal at $ 5700. It was a sales manager'* car, that'* why the high miles (120,000). Of course those are all highway miles, so the car runs super smooth. But I figured I'd better find out the interval for the timing belt. Also, does anyone know other similarly important maintenance I should do ? I figure I'll get all that stuff done at the same time if possible, once I know the scheduled intervals.

Does anyone know a site where I could find the manual ?

Thanks !

Right click save as. These are from the 2000 Bonneville GM manuals.

You may want to put model/trim/and mod details in your signature. Makes it easier for us to help.

There is no timimg belt, but it would be a good idea to do a trans fluid and filter change, fuel filter, air filter, oil+filter so you know all that stuff is done and you can keep track yourself and change stuff at your own intervals from here on in. Also see if the plugs and wires were done yet because at that mileage they should be changed. Hopefully he will take care of all the normal wear items for you. GOOD LUCK with it

Change the interior air filter too. Its located on the windshield wiper cowling, pasenger side.

Thanks everyone,

...so no timing belt, huh ? I hadn't heard that before. Does it have a timing chain ?

Yes it has a timming chain, its good for life of the motor. Good idea to change it out if you upgrade your cam.

The Pontiac Service manual states the fuel filter is not a regular service item and should only be replaced IF there'* problems i.e. hesitation or rough idling.

The manual also recommends lond conventional oil changes

Do the Fuel filter, can't hurt, and it'* cheap. You'd run into problems soon enough.

When he gets the car

re Fuel Filter - my first dealer-service on my used 2000 SSEi and they changed the fuel filter. I swear now it'* rough-idling whereas before it was fine (only 30K)... possible? and is that an indication not to go back to that dealer (they also resurfaced my rotors for rear-brake resonance; they didn't solve the issue and I later found two TSB where (1) Don't resurface rotors for noise issues, and (2) Resonance on 2000, change pads to 2001+ part number...

GM also says the Supercharger nosedrive is sealed for life and needs no oil change. I think I'll ignore that and do it once a year as always
