You will need to take off the lower panels on both sides, they are held in
with pins and just pop off. Also, you will need to take off the front dash panel to remove ash tray. It is held in with 4 screws, 2 in the front and two underneath. The
toughest part is lying upside down so you can get to the core. Its located pretty
much directly behind the ash tray and you will access it down by your foot
area. Having the lower console out will give you an idea visually of where
it is. Youll have to remove the screws for the cover to the. I believe there are 2
on the passenger side and drivers side. You will be going back and forth to
get all of them. After you remove you have to pry it out the cover to the core from the passenger
side. It is a pita and dosent seem like it will come out but it will. Dont
worry about breaking it, its pretty soild. Just keep manuvering it. Then
there is the main cover to the core.It has a few screws as well but isnt
as large of a piece. After both are out the core is held in by a bracket
driectly underneath and one on the drivers side going through the firewall.
From there just disconnect
the hoses(some coolant will leak) and replace. Make sure it fits snug, as
i said space is limited so youll probably get cramped up a bit. If you need
any further detail let me know...

SOURCE: where is the heater core located in 1997 pontiac grand prix

Core is dead center in front of the shift console. There is a bunch of plastic that needs to be removed to get to it, including (on most) the console.
Hardest part of job is getting to the heater hose ends on the firewall (difficult to get to from above or underneath unless it's on a lift, but not impossible) Haynes and Chilton have pretty good instructions for that job and you can use the manuals for other stuff as well...(about $20)
Job takes some time but is much easier than a Jeep!!!! (all day job)
Good luck

97 Grand Prix with repeated heater core problems


I'd make sure the core is installed right,like all the retaining brackets,etc. connected. Have the ph checked for your coolant. If the anti-freeze is too strong or weak it can cause this.

My 1997 grand prix gtp has a leak


Is it water or coolant that leaks inside. Water will be clear, coolant will be yellowish-green or blue. If it is clear than it is just a rubber hose that is loose from the AC drain. Replace the hose and clamp. If it is coolant then you have a leaking heater core and would need to get it replaced.

You can unhook the hoses to the core and just hook them together with a flush fitting, or hose union.

1994 pontiac grand prix leaking water


It sounds like either the heater valve which may be located inline with a 5/8" hose or 3/4" hose or the heater core is leaking, a heater core is like a small radiator.
