Why do I have no coolant in my heater?
Why do I have no coolant in my heater?
If the input to the heater core is hot, but the outlet is at best luke warm, that might mean there’s no coolant flow through the core when the engine is running and the heat is set to max for some reason. Easy enough to determine by experiment. Loosen the output hose at the fire wall.
Why does my heat work after a radiator replacement and flush?
Why doesn’t my heat work after a radiator replacement and flush? I have a 2000 Dodge Ram 2500. I just took the truck to get the radiator replaced and the system flushed. Now my heater will not heat. What could be wrong? The heater worked very well and the heater core is only 2 years old.
Why is the outlet Hot when flushing the heater core?
The OP states he has good flow when trying to flush the core yet when the truck is operating the inlet hose is hot and the outlet is cool. That certainly points to a restricted heater core. If the heater core was plugged but the coolant was able to circulate around it without exchanging any heat then the outlet hose would still be hot.
When did my Chrysler 200 heater stop working?
In December of 2015 (car was 4 years old) my heat stopped working well, and when the weather got colder I noticed that the heat was not blowing warm air on the passenger’s side. I took the car in and they opted to replace the Heater core (covered under my extended warranty) and also did a maintenance coolant flush (which I paid for).
Why is there no heat after a coolant flush?
Well, if you have leakage in the radiator cap, air can enter easily in the cooling system. Many times, when you flush the cooling system, gunk enters into the heater core and clogs it up. As a result, the heater core fails to provide warm air.

What happens when you flush a car radiator?
Let the car idle and keep pouring coolant into the radiator every time the level drops. Do this for about fifteen minutes, and then you should have all of the air bubbles out of the system. This process will clean out the heater core and bleed any air bubbles out of the cooling system. Let us know what happens. helpful?
Why is the heat not coming out of the radiator?
Well, if the heat doesn’t come out, it’s not normal. It probably means you haven’t done coolant flush correctly. At times, any foreign object or the air bubbles can be the culprit to this problem. Turns out, even foam in the radiator can cause warm air to not come out.
How can I tell if my heater inlet is hot or cold?
Select the lowest blower speed position. Turn the temperature control knob to the maximum hot position. Check the temperature of the heater inlet and outlet hoses by feel. (The air temperature around the hoses must be at least 85°F (24 °C). Does the heater inlet hose feel warm and the heater outlet hose feel cold? Go to step 10 .
Is the inlet hose to the heater core hot?
I even drianed the entire system and evacutated all the air out of the system and put a vaccum under and filled the system back up still nothing. The inlet hose to the heater core is very hot it comes out of the front of the engine but the out let hose is warm no where close to hot.
Why is my hot water heater still hot after plugging in?
That certainly points to a restricted heater core. If the heater core was plugged but the coolant was able to circulate around it without exchanging any heat then the outlet hose would still be hot. There is something else going on here. As a disclaimer, I have never been a professional mechanic but mechanical systems don’t defy logic or physics.
What happens if one heater hose is hot and the other is cold?
I read that if one hose is hot and the other is cold, then the heater core can be clogged. What could be the issue if both hoses are cold? The three possibilities are stuck open thermostat, stuck closed heater hose valve (if there is one) or plugged core. heater hoses stone cold….radiator hoses HOT….
Why is my hot water heater not blowing heat?
One way to check is to feel both heater hoses. If one is hot and the other not then no coolant through the core. Thus core plugged. If there was no heat at all and the temp gauge was reading really low, then possibly a thermostat stuck open.
