Hello all , on my mothers grand am the heater hose fittings broke on the heater core (stupid plastick junk) the other day so I`m in need of some help. I went through my chiltons manual and I couldn`t find nothing about the heater core (I`ll find it once its fixed I`m sure) . It would be a great help to me if y`all could tell me how to replace a heater core on a 93 grand am with AC . Thanks for any and all help. :boogie:

You Have To Take The Center Console Out Of The Car Once It Is Out You Can Get To The Small Bolts That Go Around The Plastic Cover That Covers The Heater Core .

Yep, you need to take out the center console. Its 6 13-MM or 15-MM bolts. You will need to pop off the shifter knob, which is a small clip you pull out with neddle nose pliers. Then you need to pop off the cover under that. Disconnect the wiring and pull out the 4 bolts undert here. Once thats out, you will see at the front of it, a few gold small bolts. Remove those, and thats where the heatercore is. You will need to get under the car and remove the heatercore lines also.

Try using needle nose plies? They are in there fairly loose. If not, its probley like a 5.5MM or 6 MM

i hated doing this job. I seem to remember only using 2-3 different sockets for the entire job.

Try using a 7mm socket, GM likes them for small screws.

I've found them on my '92 Astro Van, '96 Achieva and '02 GA.
