Start by removing the panel under the dash on the passenger side. You will need a regular phillips screwdriver and a snubby 2-3" phillips later. Also get a 1/4" socket set. First thing, go under the car and remove the heater hoses from the firewall and twist out the drain spiggot. Then go back inside the car. The heater core sits under the radio. Under the core is a tray used to catch the leaking antifreeze and drain it out the firewall. You need to remove this tray. It has 6-8 screws holding it. Once the screws are out it is tricky removing it with the center console in, but it can be done-twist and bend. Then remove the screws holding the core in place and pull out the heater core. One note on the replacement-got mine from Oreilly's for $20-the two lines coming out of the heater core swivel to line up with the holes through the firewall. If you don't swivel them it will never seem to fit. Then reverse the above order, fill up the fluid, bleed the air off and away you go. Took me about 3 hours total in a parking lot. Ruined a shirt, but got it done. You will also cuss being upside down under the dash. It's a small place for a 240 lb. guy :) This was for a 1993 Beretta. Expect some bloody knuckles and a few mental breakdowns.

Good luck, and rated the help!!!
REMOVAL & INSTALLATION CAUTION When draining the coolant, keep in mind that cats and dogs are attracted by ethylene glycol antifreeze, and are quite likely to drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantity. Always drain the coolant into a sealable container. Coolant should be reused unless it is contaminated or several years old.

For heater core removal on these vehicles, please refer to the procedure for vehicles with A/C.

Why does my 1995 chevy camaro not blow out hot air? i've changed the thermostat, it has a new radiator and hose, and new water pump. the heater core seems to be fine.

use your hand on both hoses into and out of the heater core to see that they are hot. if not the core is plugged and needs to be replaced. before you do that squeeze the hose upper and lower and the heater core hoses to make sure there is no air trapped in the system. be very very careful of the fan while you are doing this.

If your gauge is showing correct operating temperature and you are getting no heat from the heater, check (just feel them) the hoses leading from under the hood through the firewall that service the heater. One should be uncomfortably hot, the other only warm. If they are pretty close to equal or even cool, you have an obstruction in the heater hoses. Rubber hoses in the cooling/heating system are made up of laminated layers and if aged enough, the inner lining can separate and collapse blocking the flow of water either to or from the heater core. Sometimes, if bad enough, squeezing the hoses by hand can even locate the failed section; it will be noticeably weaker than the rest.
