Heater core was replaced on my 1991 740 volvo


Hi,when your Heater Core was replaced,it's possible that your heater valve (connected to one of your heater hoses ,inside the car just above the Pedals) was damaged/split .

97 Kia SPORTAGE : No heat, blower works, AC works,


Did you bleed your system of air???....usually a bleed screw near the thermostat housing...get allllll the air out...simetimes the heater core is at the highest oart if the system..therefore if there is air in system..thats where the air settles and no coolant will flow through the heater cire!!

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 the heater hoses are hot on both sides(indicating the engine is at full temp) and you feel the heat controller in dash is working properly, i would suggest disconnecting both heater hoses and backflush heater core with decent amount of pressure. if this improves condition but does not solve completely, heater core replacement is necessary.
