92 k1500 replaced heater core still no heat - 1992 Chevrolet K1500

Whats your temp guage reading?

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.

either the heat control valve isn't working, or the heater core is plugged up, what i do is reverse the heater hoses on the core to unplug the core sometimes that is all it takes but if its plugged badly you will need to replace it

The hoses are two different sizes.One will be 3/4 and the other 5/8.No way to mix them up.May be your blend door not opening alowing air to flow across your heater core.I am not sure if there is a mixing/control valve.Feel both heater hoses as well as your top radiater hose just to make sure that the thermostate is not bad.You can look on napaonline.com and search "heater"to get a look at the door motor.You can remove it and open it by hand to see if you get heat.Well hope this helped.

Heater control valve(mixing valve) or motor on your blend door.

reverse the heater hoses and drive it for a cpouple of days your heater core is plugged and by reverseing them you can back flush the heater core after 2-3 days reverse them again

Can you feel the hose going into the heater core? Is it hot? No?

You might want to find the heaters flow valve and check it. It's probably stuck in the closed position.

doesnt have a heatercore , that makes no sense, any way check thermostat , a matter of fact just replace stant, start there, good luck.

heater core is under the dash on the passenger side and the thermostat is located on the engine. just follow your top radiator hose from the radiator to the engine and it stops at the thermostat

you may need to replace the heater core and/ or the thermostat. also, make sure you have antifreeze and water.
