Heater gets cold while running down the road

Poor heat, changed thermostat and water pump. heat is hot at idle but drive in down the road and it gets cold. checked for clogged radiator, seem to have good flow, gear driven water pump. checked drive gear and coupler. everything seems fine. has anyone seen this and have any ideas? Also checked vacuum to solenoids. all doors working properly.

The thermostat is stuck open. Youv'e got a little rust in the coolant, right?

Dan how do I bleed 2004 Kia coolant car temp is good but sometime at idle heater starts to blow cool hit throttle gets great heat


I agree with your logic. Attached vid addresses bleeding. Sounds like at low rpms, not enough flow to transfer the heat. So bubble or maybe a partially obstructed core. There are a couple of vids on clearing a core... GOod luck, let us know if you figure it out.

Air lock cooling system


Not sure I follow your wording on the different temps. If the system is full of coolant and working correctly, the thermostat should open at 195 degrees which would be several miles down the road. Once the thermostat opens both radiator hoses should be warm. If the water pump is not working the engine will get hot very quickly.
Have you tried running without the thermostat to see what happens ?

Lower radiator hose stays cold after running for hours


could be you fitted the thermostat in the wrong way around ,or the plastic impeller on the water pump with a steel drive shaft has failed they end up with the drive shaft spinning but the impeller is not turning ,go for the thermostat first though .

My truck starts running hot then I turn the heater on and it blows cold air but every once in a while the heater will throw out hot air. Then the temp gauge will go down. I've check med the radiator cap...


I'd still check the thermostat. Or basically just replace it. Have you ever drained all the antifreeze and flushed the system? Good time to do both. If the hose's get real hot that doesn't really mean the thermostat open. Wouldn't they get hot even if the thermostat didnt open.? If the thermostat was stuck open you'd would have cold air and low temp gauge. Then maybe hit a pump or something and have the thermostat stick closed and have high temp. Maybe water pump. Check it when you have the belt off. Spin, pull & push the water pump pulley around. I'd replaced my water pump at about 110,000 on a '97 dodge Dakota. My 97 never had a very good heater. Always heated up more after driving. Idle never got it warmed up.

The heater gets hot and then it gets cold! what is the problem?


if the heater gets hot when it is idling but cools down when you are going down the road, suspect the thermostat. If the heat just comes and goes when driving down the road you are probably low on coolant, whit for the engine to cool and remove the radiator cap and refill the radiator, don't just try to fill it by putting collenty in the reservoir........GOOD LUCK

it could be the thermostat. if the car stays at normal operating temp at idle and only gets hot when you drive it is the water pump. i just changed one that never overheated at idle even when it set for an hour or more. as soon as I tried to drive it I would get a mile down the road and it would be burning hot. took the water pump off and the impeller was spinning on the pump shaft.

Why does my 2004 avalanche not heat up when i am


Check the coolant level. in the winter time It will not over heat very easily but vapor locks can occur and low coolant level will do what your describing ...When you drive the water pump is spinning faster causing coolant to intermittently flow through the heater core so it gets warm then cold at an idle.. also a thermostat that is stuck open will also cause this its also in the cooling system, if the cooling system is full I would replace the thermostat..good luck hope this helps

HEAT BLOWS COLD AIR WHEN IDLING ONLY GETS HOT WHEN START DRIVING


You have still got air in the system.Remove the Feed back pipe from the header tank and wait for all the air to come out while the engine is running making sure you are toping up the header tank at the same time Dont allow header tank to run dry while doing this.Good luck
