The likely culprit is your heater core. Simple test: Let you car warm up to Operating Temp. Run the heater. Under the hood on the fire wall you will see 2 black hoses conected to 2 aluminum lines about a 1/4 inch in size, feel both of these if they are not the same temp than you have a clog in the core and as a result no heat in car.

2001 VW Beetle 2.0 heater won t heat up


If you flushed the coolant with the thermostat in, chances are you didn't flush the coolant. Regardless, it's easiest to check the controls inside first. Does the blower fan work? Does the air flow change from floor to vent, to dash as it's supposed to? Does the A/C change temps when knob is turned from cold to hot? Post results.

I had flush my f150 put new water pump and thromastat still over heats?


Okay so flushed it, changed the pump and the thermostat. Check the levels of fluid in there, make sure it's correct and that you bled the air out if you need to on your vehicle(refer to manual) It's not uncommon for a new thermostat or waterpump to be faulty. It's also possible that you have a clog somewhere in your radiator or the heat lines going into the vehicle. Did you flush it yourself? Are you sure the flush was done correctly?

Engine warms well, heater fan blowing well, but very little heat comes into cab


It could be one of two things.
1. Bad thermostat. Your thermostat is pobably not opening when the engine warms up. Install a new thermostat and you should be OUT OF THE COLD. If not,
2. Your heating core and radiator is probably clogged. One way to solve this is. Flush out your radiator with radiator flush kit. Pease read your owners manual, (YOU NEED TO USE A SPECIAL TYPE OF ANTI FREEZE). If you use the the green color Presotne anti freeze, It will gradually corrode through the linings of your radiator. And the green color prestone anti freeze will blow out the radiator. So read your owners malual ( I beleive it says you have to use Dextron Anti Freeze ( Pink Color).. Replace your thermostat and flush out your radiator. Then refill your radiator with dextron anti freeze. Also make sure the anti freeze resivor is filled to the proper level.. Once you do all of this, YOU DEFFINITLY WILL BE IN HEAT.. YOU CAN DO THIS YOUR SELF ( iT WOULD TAKE ME NO MORE THAN 1 TO 2 HOURSFOR ME TO DO THIS IN MY DRIVEWAY) OR YOU CAN HAVE THIS DONE AT ANY QUICK LUBE LOCATIONS... HAPPY MOTORING

Luke warm heat in a 2002 expediton


Start with Flushing out your cooling system. Flush it out with Preston Radiator flush, you have your preference of ether the super flush which takes 3-6 hours or the 10 min flush which is good if you don't have the time to flush out your cooling system.

After you have flushed out your cooling system, replace your thermostat and you should be good for another cold winter driving. What happens is that after a few years of the coolant not being serviced, the coolant crystallizes and clogs up the heater core and radiator causing poor circulation. Poor circulation will cause poor heat and or overheating issues to the engine.

Before you go through all that inspect to make sure you have the right amount of coolant in your cooling system.

Good luck and thank you for using fixya

My car is running hot do u think i need to change the motor?


buy a radiator flush kit, some prestone flush additive, and even maybe a new thermostat, and a simple haynes manual for your auto. The manual will tell you where and how to change the thermostat, and how to drain the radiator, and how much radiator fluid you will need. The flush kit will instruct you where to put the flush fitting.
Remove the thermo, flush the motor, install new thermo and gasket. Add radiator fluid, done. This should solve your over heating probs. Don't let it over heat! You can cause major probs then.

You could always take it to a shop and pay the $200 to do it for you. My way would cost you less than $50.

please click yes if this helps. thanks

2000 Cherokee not warm


Aside from flushing the radiator and heater core andreplacing your hoses, did you happen to replace your thermostat. Sounds to me like that's your problem if everything else seems to be in order. If you change the thermostat and still have no heat, you might check your vacuum lines running to the back of your heater controls inside your dash. That's really the only other thing that I believe could be causing your lack of heat.

Hope this helps! Have a great day and try to stay warm!
