There is a drain on the bottom of the radiator that has "ears" on it. It should be on the extreme lower left or right. Use pliers to open it up.

1997 ford Taurus 3.0 6cyl. Has not heat


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.

I have no Heat in my 2000 Ford Taurus!


If the heater core bypass refers to the water flow to the heater core, I would wonder why you did not flush the heater core as part of the system. You can drain water from engine, disconnect heater hoses and add a short hose to the heater and force a garden hose to flush the core.

I have not looked up the particulars for which heater system is on your car. Some just use duct-work to close off air flow through the heater core and the heater core always has hot water in it. Others will use a valve to shut off the water flow through the heater core and they can be either electric or vacuum operated. Combination systems are the third system which controls water flow and duct air flow at the same time.

Some of the Premium Climate control systems with Electronic displays have a computer diagnostic system which self-diagnoses problems but you need the sequence codes and explanation of where the bad part is located.

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.

1999 Taurus, no heat. Not good with winter coming.


If the coolant is full and the thermostat is bringing the temperature of the engine up to par than I would bet with 95% certainty that the heater core is plugged.

You can try back flushing it. You'll need a pair of pliers, a drain bucket, a piece of heater hose the same diameter as the heater hoses (about 3/4"), and a couple of needle nose vice grips. Pinch off both of the heater hoses at least 6 inches or more from where the attach to the heater core with the needle nose vice grips. This will minimize coolant loss from the engine. Put a drain bucket under the car to catch any coolant that runs out (by the way this is going to make a huge mess). Remove the clamps and heater hoses from the heater core. install the short piece of 3/4 inch heater hose onto a garden hose. Install the other end on one of the heater core tubes. Using low water pressure flush the heater core. You should see a lot of nasty stuff come out. Repeat on the other heater core tube. Continue this process until the water runs clear.

Reinstall the heater hoses, remove needle nose vice grips, Top off the coolant in the radiator, start the vehicle and let idle. Continue to monitor the coolant level and add as necessary. You should start to get some heat with the blower setting at low. If the heat goes away at higher settings than you'll need to repeat the procedure described above. Sometimes driving for a couple of days will help loosen up the debris in the heater core.

Also if the coolant is really dirty that it will help too have the cooling system flushed as well to prevent the debris in the coolant from settling in the heater core after you have flushed the heater core.

There is always the possibility of the heater core leaking after an attempt to flush is made. Using low water pressure will help minimize this.

1998 ford taurus no heat,replaced thermostat,heater core and the blend door motor seems to be working, flushed radiator, and still no heat, any suggestions?


You might have to purge the coolent system cause when you change stuff like that you normally have to bleed the the colent system. So what you have to do is run the car untill your temp gets to 195 degrees the cut the car off and let the coolent drain down and then refill and geep doing that untill you have heat.

I have an air lock in my 1998 ford taurus se radiator .it seems like after a couple of minutes having warm air it begins to get cool again


Sounds more like a clogged heater core than an "air lock".

Flush the cooling system - twice!! with a decent cooling system cleaner - and be sure that the heater is on full heat when doing it.

I bet that you see a great improvement in performance!!

Not sure


There is a restriction some where Check radiator and heater core have system FLUSH. can be done by removing thermostat and drain radiator replace with water add a 10 minute FLUSH can be bought from Auto zone and let vehicle run for 10 minutes and then drain. At this time you should also disconnect heater core hoses( 2 black hoses going into fire wall) using garden hose flush Core out. More than likely its clogged(MAY even be disconnect if you are NOT their original owner . Refill the system when finished with a 50/50 mixture of antifreeze and water and replace thermostat run as usual and your problem should be solved. Good Luck contact if you need more help.

Heater in 1998 Ford Taurus


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!
