SOURCE: how to replace heater core in 2002 chev s-10

Well first, if your talking about the radiator hoses when you say the bottom hose is warm and the top is cold, that would suggest to me a stuck thermostat. If not, then the heater core is located inside the truck under the dash. You can follow the heater hoses under the hood to the firewall and that will tell you where, under the dash the core is located. It is kind of a big job, as all the under dash covers will need to come out as well as the glove box. The heater core is inside the heater box, a black plastic box that will also need to be removed. It is important to note that when you are reinstalling the heater box after you change the core, it must be completely sealed, either with RTV or two sided insulating tape.

This was the procces on an 86 chev 1/2 ton. Should be the same. Remove glove box. Undo manual controls for duct work. you'll see them there behind where the glove box was on top of the heater core housing. Bemove screws/bolts. Don't remember how many there are. Undo hose clamps in the engine compartment. Remove heater core.

I have a 1995 chevy suburban. Heater is not working in front or rear. Have replaced t-stat, and temp doors are working, but I seem to have no flow to either heater core.


I have the same model suburban. I replaced the heater core. You will probably end up replacing both. You can buy them at Oreilly or AutoZone. and install yourself with a manual.

How to replace heater core on a 1989 Chev. 1500 (350)


Start by draining the coolant, disconnect dash board wiring harness from pcm behind kick panels, disconnect eye shaft, unbolt dashboard and remove dash. (Remember to tape steering wheel in place as it might have a clock spring). You might have to remove some trim panel on top of dash or cluster from dashboard to gain access to retaing bolts, disconnect heater hoses from heater core in engine compartment and remove heater core, reverse install.
