I have a 1996 Bonneville and it has a Phillips head screw on each side of the armrest. If yours is like that then you should be able to just unscrew them and pop it out.
I would like to have a dimgram to show me how to put the hater core out and in on my 94 Pontiac Bonneville
If the Bonneville is like my GTP then the fuel filter is in front of the fuel tank
Utah. they are named in honor of one Captain Bonneville, USA a nineteenth century explorer for the Army(in that sense like Lewis and Clark). The Pontiac Bonneville is named after the racing site, as it is the top of the Line Pontiac.
On top of the starter--Looks like a juice can
under the hood. its the thing that looks like an alternator.
The radiator petcock drain on a 1999 Pontiac Bonneville is on the bottom of the radiator. Look for a small black plug that looks like the plug found on a thermos or cooler.
If yours is like my 2000, check under the back seat.
I have a 1998 bonneville. It does the same thing. Now i have to fill it like every 200 miles or so.
In many of the larger GM cars like the Bonneville, the battery is located under the back seat cushion. Need to take out the seat cushion and you will see it mounted in the middle...
