You should get a Haynes manual. You have to go on the inside of the vehicle and remove the panels, to get to the heater core. Then you have to jack the vehicle up to remove the heater core from the hoses. This is a tedious job and takes time. But not to difficult. I'm not a mechanic, and it took me about 4 hours.

I have a 92 Pontiac Sunbird SE. Blows hot air but very week. I replaced the blower motor and sensor already. I can hear the motor running the way it should but it is not blowing hot air in the vents for...


Does the car have A/C? I've seen where the A/C evaporator coil springs a leak and it will be soaked with refrigerant oil, then every speck of dust or dirt that comes along sticks to it. Pretty soon it's plugged solid, the air for the heater has to pass through the A/C coil along with the heater core. No A/C, it could be that heater core fins are plugged. Also, some cars have a "cabin filter" if that's plugged it won't allow air to enter the system at all. Call a dealer or auto parts store to see if vehicle is equipped with a cabin filter. Good Luck!

Water leak right next to inlet hoses for heater core . could there be a drain hole there


Yes, they typicaly about the same size as a pen. Make sure that it is just water comming out, and not coolant. If water, this is normall from condinsation, if coolant, you will need to change the heater core.

My 93 sunbird is leaking antifreeze from the firewall on the drivers side


The heater core is located there just under the dash in the plastic enclosure. AC parts may also be there. Remove the heater enclosure to expose the core. You will have to disconnect the heater hoses from the engine to remove the core and enclosure. Then inspect the core for the leak, usually at a line connection.
The core can then be soldered or sent to a radiator shop for repair. You should have some expertise in repair to attempt this job on your own, otherwise take it to the shop. Some people would try radiator stop leak since the heater core is part of your cooling system, but I wouldn't recommend it. Remember to replace the anti freeze when you are done.

I have a 1994 Sunbird V6 that is Leaking Coolant from an Elbow coming out from the Firewall. How do I stop this?


Aside from disconnecting your heater hoses, the only fix is to replace the "heater core". The "heat" function of your climate control system relies on heated engine coolant to work. The small elbow that you describe, is most likely the condensate drain. The "heater core" and the "evaporator core(for the a/c)", are located beneath the dash assembly in an enclosed housing. The "heater core" should be serviceable without removing the complete housing as with some vehicles. I hope this helps
