    It's possible you have a head gasket issue? Other than what I have already suggested, I can't think of anything else, at the moment.

What about the radiator? Water pump? Can you check for coolant flow? There could be air in the cooling system? Do you trust your temp gage? Are there overheating issues besides the temp gage showing hot, like coolant overflowing, under the hood, somewhere?

SOURCE: 93 ford festiva heater only blows cold air.

The heater only blows HOT air when set on defrost or floor settings. If you have the lever set for vent, only cold air will come out. Check to make sure you set the controls to floor or defrost. This is standard for all Festiva's.

SOURCE: new thermostat,waterpump,coolant,block flushed rad

take the thermostat out and heat it up in a pan of water to see if it will open when it gets hot.
you should see it open when it gets hot.use a cooking thermometer to watch the temp. it should open between 180 and 225 deg.

You may have a heater valve that is on one of your heater core hoses may be bad.

SOURCE: 2002 sebring overheats, heater blows

Ohh that sucks!
I bet the engine light is on, too, huh? I bet if you took it to read the codes, it would say cooling system inefficiency, too.. Mine did the same thing and it was the timing belt slipping o the water pump.

Here is a walk through of how to find out for sure. It works on any engine that is running too hot.

Thanks for the vote.

My 1998 S10 Chevy pick up heater only heats when I hold the gas pedal to the floor. When I let off the gas it slowly starts blowing cold air again. what is your thoughts on this problem?


Sounds like you have a restriction in the heater core. You can try removing the heater hoses at the firewall and putting a garden hose to the bottom inlet to reverse flush the core, if this is unsuccessful you will probably need to have the core replaced.

I have a 1992 Chevy caprice how do I flush the radiator


Remove hoses and use garden hose to run water through both tubes then reverse the flow and flush some more. If that won't clear the debris then replacement will be necessary

What should the heater core inlet hose temperature be?


It sounds as if you have a blockage in your heater core itself. You can usually remove both hoses from the core at the firewall and using compressed air, blow backwards into the heater core until it is cleared. While you are there I would suggest changing the plastic elbows that come off of the engine if they have not been changed already as they are known to crack and cause problems. They are even remaking them in metal instead of the plastic.

Suburban overheats while driving but cools while stopped. Heat works very good


the flushing of the radiator did nothing as it only cleans out the already open cores but the blocked cores are still blocked. Fit a new radiator and possibly the bottom radiator hose as it may be sucking in as well restricting the flow of coolant from a partially blocked radiator cores.

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.

How to back flush heater core 2007 grand prix


drain coolant system locate heater cores hoses going through firewall you need to buy the radiator flush kit at any auto parts stores. remove heater cores hoses from one end or buy extra long heater hoses same size as heater core hoses in vechicle at auto parts store use the flush kit when you flush through one of the heater core hoses let the other hose drain in a drain pan when you use home garden hose use low water pressure dont use garden hose to the max or you will rupture heater core. your best bet let radiator shop flush whole coolant system. because heater cores hoses are in a tight spot.make sure engine off if you just going to flush out heater core only .after flushing heater core good time to replace heater core hoses.if job too hard or complicated let radiator shop flush out radiator the engine block and heater core because if radiator stopped up or engine block stopped up the gunk and rust will reenter plug up heater core.if you tight on money you can flush out your own radiator.drain out radiator using large drain pan. remove top radiator hose and remove bottom radiator hoses connect to water pump.use garden hose with flush kit part with water pressure not too high put garden hose to top radiator hose run water until clear water run out bottom radiator hose in drain pan,the flush out engine block remove thermostat.if you had another spare thermostat housing with RTV SILICONE SEALANT THAT HAS SET UP INSTALL THERMOSTAT HOUSING BACK TO ENGINE WITHOUT THERMOSTAT FLUSH OUT THE ENGINE BLOCK, WHEN DONE INSTALL NEW THERMOSTAT THEN INSTALL ORIGINAL THERMOSTAT HOUSING WITH NEW ORING WHICH YOU BUY AT DEALERSHIP.IF ALL SOUND COMPLICATED LET RADIATOR SHOP FLUSH OUT COOLANT SYSTEM.

My truck wont blow out any hot air, just cold. i put a new radiator and thermostat in it. it is full of anti freeze


Try removing the Heater hoses from heater tubes(be careful not to break heater tubes off) then back flush heater core with garden hose(Don't use a lot of pressure). Jell from antifreeze builds up in the heater core and blocks the coolant flow. If it is easier, remove the heater hoses from the engine, that is safer. Back flush the heater from the hoses. To Back Flush (The hose coming from the water pump is the inlet)(Hose going to Manifold is outlet) Back flush outlet hose! To much water pressure may cause damage to heater core!!!! Do Not ues AIR!!!!
