Re: Car runs at normal temp. but heater does not heat
Get a prestone flush kit. Splice in the t adaper with the heater hose and follow the directions. Check petcock on side of radiator for drain plug or remove lower radiator hose if you want to drain it next time.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

Empty cooling system and reverse flush the heater core with water hose till water comes out clear. Then reverse procedure till water is clear. Fill system with water and turn car on, while car is running open drain plug and continue to keep radiator full while draining it at the same time turn on your heater with heat on high and blower on high When water is clear flush system and wait for engine to cool down. Refill with antifreeze and turn engine on, check for leaks and to see if you have heat. If still no heat change heat core.Let me know how you make out.
disconnect the heat hoses going into fire wall , put hose into one with pressure and flush as it sounds like it could be bloked in the heater core,the other thing that could be the problem be the hot ,cold switch as it restricts the flow to makes the heater hoter or colder , it might need tlc or replacing as it is manaul not elec
replace the thermostant again this time get a hotter temp thermostant and buy it from the dealer, the other thing is that these cars are known for the temp sensors being bad this would give you the false reading on the gauge but would not affect the heat, if its taaking a long time then i would replace the stant and this time or before replacing the stant i want you to flush out the heater core, remove the hoses from the heatercore and use a water hose to flush water through the heater core, a plugged core will not throw heat or will start to allow water to flow when it gets good and hot to flow through the retricted core due to rust and crud, try the flush first and then try a new temp sensor if the flush helps the heat, hope this is helpful good luck.
The heater core could be clogged. If your antifreeze is orange , then it is Dexcoolantifreeze which causes slime and sludge to build up in the cooling system. It can clog a heater core. My suggestion would be to drain and flush the entire cooling system with Prestone Super Flush. Put in a new thermostat while your at it. Refill the cooling system with a green antifreeze that is labeled compatible with aluminum engine parts and radiators.Do Not refill with Dexcool antifreeze.
the van will be okay just dont fill cooling system with water and leave it then it will freeze the motor. also you might freeze its not an easy job, is the core leaking, or are you not getting heat, if its no heat then just flush the core with waterhose from hoses going to it, just remove the hoses to core and use waterhose to flush out, go into both hoses one at a time do this a few times and you will have heat. if its leaking then replace it.hope this helps.
couple possibilities - is the engine temp gauge in the normal range? if not, could be a thermostat issue. otherwise, have seen heater cores plug up on these. a heater core flush followed by a full cooling system flush will fix this.
i would suspect a couple things. if the engine is not running at correct temp. 195 degrees or so. replace thermostat and recheck. if engine is running at normal temp and is not overheating at all. would suggest flushing heater core to see if helps. if not then heater core replacement may be necessary these ford cars and trucks are notorious for poor cooling/heating systems due to the coolant used
This is a common problem with the Taurus. You have an air lock in the system. You need drain the rad and open the cooling system at the highest point. This is usually the upper hose on the heater core.Fill the rad very slowly until the coolant comes out of the upper hose connection. Once done run the car with the hose reconnected and the rad cap off.Put a container under the rad filler.Run the car until it comes up to temp.Slowing top off the rad with the car still running. This should do it.
When u flushed the radiator, what did u find? Was the old coolant dirty, rusty, sediment in it? What u describe sounds like the core is plugged up w/ junk. This would be my 1st choice of the problem, especially if the coolant was rusty, cruddy, as described above. It wouldn't be an air pocket (after a couple of years). Some cars do have a valve that opens and closes to allow the hot coolant into the core for heat, or a flap door that opens to allow the fan to blow air thru the core for heat, but the fact that this started when u flushed the system leads me to believe it's a plugged up core. U could try to flush the system again, make sure the heat is on when u do, so u have circulation tthru the core to help flush it out. let me know how u make out. good luck!
