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.

SOURCE: I have a 1999 chevy silverado and I need to change heater core

Not a whole lot different. Just need to keep removing plastic down at the heater until you get to the heater core. Then disconnect it on the firewall side.

I have a 2002 Chevy tracker. It's been running hot on the temp gage. So, I have changed the thermostat and replaced the radiator hose because of corrosion but it still overheats and when I turn on


If there is cold air coming out the heater than there is air in the system. After you replaced the thermostat did you run the engine at idle with the radiator cap off until the engine came up to operating temp? Doing this will purge the air from the system.

Replace heater core in 2002 chev tracker


Changing the heater core on a '00 Tracker is moderately difficult. To do it right you must remove the entire dash pan (just like a Ford), but besides that it's easy. The problem with removing the dash pan is the you will probably never get all the rattling out after you reinstall in. As far as getting the core you local parts store should be able to get it for you. You can go to www.advanceautoparts.com or www.autozone.com and check on-line to make sure. If they can get it and you don't mind using used parts go to www.junkyarddog.com (it will link you national salvage yards) good luck.

You need to have the cooling system/heater core tested for leaking. Those symptoms sound like the heater core has failed.

Cant get heat to the inside


Have you checked to see if small vacuum line on firewall under the hood is a-ok ( no breaks or cuts) it's usually on passenger side and goes through the firewall to inside.
Also I think when the heater core goes out you have no defrost either so when it is cold and wet outside your windshield will fog up.Also did you check your fuses.
