Very awkward and messy. 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
how do i replace a heater core in a 2001 Chevrolet blazer
Behind the Radio/ Heater Control, center console, mounted against the firewall. And yes, it's extremely difficult to replace. It involves basically tearing the entire dash board apart.
It is in the air conditioner /heater case behind the glovebox.
What is the problem? Do you want to replace fan or fan clutch?
have a professional do it
take it into a shop and let them do it. unless you have plenty of time and patience to do it yourself. get a chilton's or hayne's manual and follow the diagrams/instructions. you will have to take the dash apart, etc.. to replace it.
BIG JOB Get a manual on your car from DISCOUNTAUTOREPAIRMANUALS/COM and it will have pictures and everything.
