A heater core only needs to be changes if it is blocked with rust or is leaking, a more plausible reason would be a stuck open thermostat in the engine cooling system. Also check under the hood for hot coolant in and out of the heater cores hoses, those are the small hoses going to the firewall and into the truck.

Heater not blowing hot air & vacuum leak


sounds to me the hissing is the sound of a leaking heater core. Its smells weird becuse coolent usually has a sweet smell that is very noticeable. I bet the floor is wet/carpet damp in the front near the hissing. I bet your coolent level is low as well. Replace heater core.

I have a 2002 Jeep Liberty Limited, 3.7 L motor. The heater will not blow hot air. The A/C and fan work well. When I turn the temperature dial to hot, there is only cold air coming out. Can you assist me?


Jeeps are notorious for having broken temperature control (Blend Air) doors. A malfunctioning Blend Air Door actuator probably caused it to break. The dash will have to be removed to replacethe door and the door actuator.

95 Jeep Grand Cherokee....I have no hot air. of course I assumed heater core at first but there is no puddle on the floor board and both hoses going to and from the heater core are hot at normal running...


Your heater core could be plugged with dust if this problem came up slowly I would suspect that. Another thing that cold be wrong is a trap door is not opening these are operated by cables vacuum or stepper motors. Confirm that something happens when you move from cold to hot on the control.

Not enough heat comeing out . not looseing antifreeze, not leaking on floor boards , not blowing on windshield , blows warm air on low but when on high blows cold air , have new thermostat and water pump


Check that the hoses running from the cooling system to the dashboard / firewall are not bent / creased in a position to impair the flow of hot water into the heater core in the dashboard. Disconnect these hoses at both ends, and inspect for mineral deposits, or rust, that might be blocking water passage too.

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 not working


First you have to identify what causes the problem.
To do this you have to:
1) When engine is cold check the level of coolant. If it is low fill it up.
2) Start engine and check if engine reaches regular temperature. If your engine is not heated enough it means your thermostat does not work properly and should be replaced.
3) If engine temperature is normal, then check the temperature of pipes that go to/from heater core. These pipes are located up the fire wall (easier access is from the passenger side). If pipe/pipes are cold (even engine is warm) it means you heater core is plugged and should be flushed. Keep in mind, flushing the whole cooling system is different from flushing heater core.
4) If pipe/pipes are hot/warm, turn off the fan, switch controller to the hot position, wait for 3-4 minutes and turn on the fan. Note if the cold air blows first or warm air blows first but it cools down in 5-10 seconds. If the air blows cold than it is most probably the problem with blend door or blend door actuator.
5) If air blows warm first and then cools down, then while running engine and remaining the transmission in PARKING position, press on the gas pedal until your engine reaches 3,000 RPM. Check if your heater blows warm/hot air. If it does, then your water pump does not work properly and should be replaced. If the air still cold, I would suggest flushing the heater core.

My heater is blowing cold air what can I do?


Hello, The normal operating temp for this car is about 95°C. If your car is not running this temp after it warms up, you probably have a bad thermostat.
If you are not getting good air flow, have someone ck your cabin filter. It could be stopped up bad giving you weak airflow. It is located on the right side at the bottom of the dash.
If you find this information to be correct would you please enter a "fixya" rating.
Thanks, Gator241
