When you do the inside heater core you need to back flush the system. then do it forward do this a few times. then put back together and leave the top off the filler tank for the water. run engine keeping it topped up with water. have the heater open but not on fast blow 0 or 1 get the engine up to temp and as the fan starts to kick in turn engine off this will make a lot of the water come out don't top up at this point, now wait for the engine to cool down and then top up. wile the engine is running you will see the air come out and bubble out, you should notice it getting hot inside the cab but carry on with it till the end. as i have put in this post run for a day without anti freeze in then put this in, by taking the cap off. and undoing the the bottom pipe. then when tank is empty put the pipe back on and fill with anti freeze. full strength not mix. run engine for 5-10 min without the cap on then let cool down and put the cap back on should be all good then.

SOURCE: 2002 dodge 1500 Changed radiator, thermostat, and hoses. No heat

Why was radiator replaced?Did it have heat before ? If it was plugged, the heater core may also be plugged. Try flushing it with a water hose in both directions. I dont know why the botton radiator hose would be cold, the radiator should be a uniform temp and the air coming through the radiator should be HOT, when the engine is at operating temp. What condition was the old coolant? if it was rusty, the water pump may have lower flow than normal.

If it is fogging your windows, you have a leaking heater core. Dash removal is required to fix it.

I have like a rust colored dirt coming from the radiator and radiator hoses. I've replaced the radiator, thermostat, coolant temperature sensor and water pump. I have no heat. Car registers hot but no...


Have you backflushed the heater core? Check to see if both heater hoses are getting hot and if not flush it if possible. NOTE: most modern cars run hot water through the core at all times, but direct the inlet air through the core to supply heat by use of flapper doors usually operated by vacuum actuated devices. Vacuum leak, bad check valve to vacuum reservior, or bad actuator can prevent any heat.

When I put the heat on in my car it blows warm air for a few seconds then goes to blowing out cold air.


The lack of heat in the car has little to do with the car's cooling system, other than the hot coolant is the heat source. 95% of all "no-heat" issues are related to heater controls and/or the heater core itself. Since you get some heat, and then it goes away, this indicates a probable vacuum leak in the heater controls. When you select heat, vacuum is directed to a vacuum motor. This motor operates a vacuum actuator that moves a linkage that moves a door inside the heater box to direct the interior air through the heater core. If this actuator has a leak, it will activate, then as the vacuum leaks off, deactivate. You probably need to have a part replaced in the heater actuator mechanism.

I have a problem with cold air from heat vents.


Replace the thermostat. When the engine is hot. There isn't a hose on it that you can hold for more than a couple seconds. 200+ degrees.

Feel the hoses going to heater core, one should be hot and the other warm. If one is cold or both are then heater core is clogged. Make sure heater control valve works and as vacuum to it and or the cable is free.

No heat , replaced radiator , water pump, rad. cap , hoses and flushed system twice.blows cool air.whats left?


Thermostat.? if you haven't? Do it first then try it. While the car is running for a while touch the heater hoses that lead to the firewall. if one is cold and one is hot? You have a blocked Heater core. Follow the hoses back to the engine. Unconnect them both. By using a garden hose flush out the heater core do one side and then reverse by doing the other hose Lots of junk will come out so be care ful. Mistake people make is "Flushing the system" That doesn't mean your flushing the heater core.
Seeing that you have done everything else it could be the thermostat which you didn't list or the heater core being clogged. When you finished installing the thermostat and flushing the heater core out. Replenish the coolant system . If you have a bleeder on the thermostat housing? use it . loosen it and top off the fluid until you see fluid comeout of the bleeder. The system being air bound would cause no heat..

ONLY WARM AIR FROM HEATER, REPLACED THERMOSTAT, STILL ONLY WARM AIR. UPPER RADIATOR HOSE & HEATER CORE HOSES ARE HOT.


The next possibility, if you haven't already thiught of it, is as simple as making sure there is enough water/antifreeze solution in your radiator. If the level is too low, your hoses will get hot, but there will not be enought water to circulate into your heater core.

No heat in my 97 dakota noticed when motor is warm both of the radiator hoses are cold what is causing this


good day, heater core/coil is leaking antifreeze and needs to be replaced. The heater core works in conjunction with your engine's cooling system. The function of the cooling system is to remove heat from the engine, and it does this for the most part by sending the heated anti-freeze to the radiator located in the front of the car. The position of the radiator allows outside air to blow across the radiator thus cooling the anti-freeze. The anti-freeze is then sent back to the engine. Hot anti-freeze is circulated throughout the cooling system by the radiator and heater hoses. Think of the heater core as a small radiator located inside the dashboard of your vehicle. hope this helps, have a nice day.

My heater in my dodge caravan does not blow hot air. When my engine finnaly heats up, it blows only warm air. Its a 2006


First of all make sure your anti-freeze is at specification level's as well as make sure With the engine cold start the vehicle remove the radiator cap and make sure you see the flow of anti-freeze while keeping your hands as well as your clothing away from moving parts feel both hoses going into your heater core if the one on top of hot one on the bottom is cold then you have a Clogged heater core in which case you will need to flush the system . a simple garden hose will do the trick simply remove Both hoses to the heater core with the hose at the bottom line apply the garden hose until liquid comes out at the top of the other hose will probably see a lot of gunk. Also ensure that the vacuum line to the round ball under the hood is connected and not dry rotted.this will cause a vacuum leak to not allow the switch to fully engage from cold to hot. I hope this helps you.

Heater only blows warm air.


The hoses from your heater core should be very hot to the touch. Check the hoses going to the core from the water pump. It should be very hot. The return hose should also be very hot. Now check the hoses going to the core. If they are not the same temp, then your heater control valve is not working correctly or the vacuum is not working. At any rate, locate the vacuum line going to the heater valve. Remove the silver bar on the valve from the plastic plunger arm. You will have heat all the time now if it was only a vacuum problem. You can fix it later when it's warmer out. BTW a 200* thermostat will make your heater even hotter.
