Hi Guys!

I have this friend that wants me to remove, repair and replace the heater core in his 1999 Pontiac Grand Prix. I'm from the old school when heater cores weren't that much of an issue to repair/replace. These newer cars are more compilicated. I'm not short on tools, but could use some help with deciding if I want to get into this.

Thanks in advance for all the help I know I'll get

P.S. Maybe we should have a cooling/heating system section for questions?

1. drain cooling system
2. remove drain hose from the bottom of the heater case
3. remove panelse from under the dash and steering column trip cover. also remove center console.
4. remove the heater outlet duct and glove box
5. remove heater core cover

Thats directly out of a haynes manual for an 88 - 99 Grand Prix. And from the pictures im looking at the heater core is right in the middle of the dash twards the rear of the passenger compartment. Doesnt look too bad to me. hope this helped

97,that makes it sound easy. . Its not a fun job, I would think twice if you have never done one on a late model car.

lol... the haynes manual is good for that. they make it look like a 15 minute job, then 4 hours later your just getting the part removed that you needed. i wasnt sayin it WAS easy, just LOOKED easy. guess i shoulda clarified.

i did a core on a cavalier, and that wasnt too easy because the stupid thing was mounted up against the firewall between the blower motor and firewall.

Anyway, like Steve said, if you've never done a late model car i would try to steer away from it unless you have a whole weekend to mess around with it that way you can take your time.

well, Good luck if you decide to do it!

Thanks for your help......everyone! I think I'll stay out of this. I have plenty of truck work to do wthout getting into a posible three or four day mess. I appeciate your advice and, by the way, you're right about Haynes manuals.

What ever happened to Motor's manuals?
