SOURCE: replace a heater core in 2000 chevy blazer

it is located under the dashboard against the firewall of the passenger seat. i recomend buying a repair manual from your local auto parts store before attempting as it requires draining, flushing, refilling and bleeding the cooling system as well as removing many other componets like the entire dashboard and thermostat

SOURCE: How to replace a heater core in a 1994 chevy 1500

As with all vehicles it seems the first part that they build around is the heater core. It is under the dash above the floor housed in a black plastic sealed box. Sealed with goop. Locate that box and start removing everything around it that is peventing taking the cover off. Of course disconnect the heater hoses under the hood a thefirewall.

Warning it is never as easy as it sounds.

Step by step to remove heater core on 1991 corsica


Here's a link to replacing your heater core,it's a job,be sure to replace your seals that the boxes connect to each other or air will go thru,your's is probably dry rotted.Also make sure your outlets are pointing in the same direction on both heater cores,if they are different,then your heater hoses going to them will be too short,happen to me. Use a 2x4 to hold dash up,I did.Repair Guides Heater Air Conditioning Heater Core AutoZone com

Coolent leaking from rear of engine can not see from where. When I stopped the car the fluid kept coming out. Engine overheated, I checked the front hoses they are dry and no leak from the radiator. What...


You could have a leak coming from the intake or even the heads. Before digging into those difficult items, I'd check all of your freeze plugs for damage/wear/rust/leaks.

I am looking for the heater core on a 1996 chevy corsica. Is it behind the firewall and can i access it from under the vehicle?


It is inside the vehicle towards the centre front of the floor, against the firewall and floor. If you want to remove it you will need to drain the coolant from the radiator and disconnect the 2 hoses going through the firewall. Remove the side panels from the centre console.Then comes the heater ducting and the core cover. You have very little space to work in so lots of patience is called for. And begging, followed by swearing and pleading. Once done you will have saved yourself upwards of $500 in labour costs.

How do i change a heater core on a 1995 chevy corsica


Changing the heater core is a simple process. Getting to the core to actually change it can be daunting if you have never changed one before on a corsica. All cars are different in that you have to remove enough dash parts to actually allow you to get to the core and they are all different. This is why labor charges are so high for changing a $50 part.I have never changed one on a Corsica myself. If you do this yourself, take digital photos as your go along so you will be able to put everything back in the correct order. I know this is not really the answer you want, but you are probably not going to get detailed instructions on how to do it, other than just remove enough parts to get to the heater core. Go slow and figure out how the parts come off and what parts to remove. Not an easy repair even if you have done it before. Good luck.

1996 chevy corsica 2.2 liter engine. Coolant temp never reaches above one-quarter hot, therefore no heat. I've put in four thermostats, installed new radiator, disconnected the cooling fan, still no heat....


You may have a stopped-up heater core. It's a little radiator inside your dash; it's where the heat comes from. I don't understand why the temp gauge isn't reading any higher than that...
