SOURCE: How do replace heater core in 2002 Pontiac Gran Prix

i do believe you have to take the passengers side dash apart behind the glove compartment. go to autozone and get a manual or go to the library and check the chiltons manual. this is not an easy job. how bad is the leak? if its not bad these heater cores are made of all aluminum. i would buy a bottle of that radiator additive and see if that takes care of the problem first. it only cost about 5 bucks a bottle and it may permanantly fix your problem.

Heater core leaking


Must replace the heater core. Its usually a very hard job that requires disassembly of the dash. If you insist on doing the job yourself, I suggest getting a repair manual from your local auto parts store so you can use it as a reference as you work. Here is a link to a video on a 98, yours will be very similar: http://www.youtube.com/results?search_query=1991+Pontiac+Bonneville+heater+core+replacement&sm=12

Why wont the heater blow out hot air in my 1995 pontiac bonneville. it will only blow cool air


If the heater hoses are getting hot, the problem may be a faulty blend door under the dash. The blend doors direct air thru the heater core and the vents.

Procedure for removing heater core from 1978 pontiac bonneville


Pull the 2 hoses from inside the hood fire wall (drain anti freese first)
Pull all carpet on passenger side and look up. Should be 4 bolts holding it on plus a cable which opens the heater door. Disconnect cable and remove 4 bolts. They come out either from the inside or from the firewall side. It is a hard job but can be done.
