if your truck has a body lift the space between the bumper and the lower core suport needs to be filled. and if its a suspension lift the air that is now geting redirected up from the front axe needs to be blocked

92 chevy 1500 silverado Changed thermostat,heater core, core hose not hot. No heat


It sounds like your heater core is stopped up. try flushing it out, you can use a water hose. and if you cant get it to clean out then you will need to change the heater core.

1994 silverado heat is not working. Replaced thermastat, heater core and checked fuses. Still no heat. The blower motor (high, med, low, is working fine.


I think that one still uses cables to control the blend doors and vent doors. Are you sure those are working and/or connected.

Also when you replaced the thermostat and heater core did you bleed the cooling system? With the engine cold remove the radiator cap and let engine idle up to operating temp while keeping the radiator topped off with coolant.

Are the hoses going to the heater core hot?

No heat


If it had dexcool orange coolant in it, the heater core is probably plugged, pull off the hoses and blow air through it, the dexcool breaks down and clogs everything. I had this problem a month ago and the core was plugged badly. Hope this helps
