I'd suggest looking at the fan clutch. When you increase the RPM of the engine the fan is spinning faster and pulling more air through the radiator - at idle, it isn't pulling enough air.

    okm ill look at that ,but i think there is a sensor that tells the fan to turn ... right ..???

  • Johnny Tumlinson May 26, 2011

    Yes, the fans in your Taurus are 2 speed fans. They are turned on and off by the PCM through it's monitoring of the engine temperature by the "Engine Coolant Temperature Sensor" and the vehicle speed. Low speed turns on at a engine temperature of 210F99C and turns off at 204F/96C. The fans will turn to high speed when the temperature reaches 225F/120C.

    When you "race" the engine, you are making the water pump circulate coolant throughout the engine faster, therefore cooling it down. It is possible that the ECT is providing faulty information to the PCM and not letting it turn on the fans.

    However, I'm guessing that I was making the improper assumption in my original solution that the ECT had already been ruled out as a possibility since you went to the trouble of replacing the heater core and thermostat...

    yea that is what a mechanic told me to replace first ... so he did ......and also the heat and ac doesnt work all the time so thats why iam thinking the sensor ......

    I'd say you are dealing with separate issues. Get the overheating issue fixed first - then worry about the HVAC issues.

How do I fix the heat


You have one of two problems. The heater core is plugged /
restricted or there is an inoperative internal blend door motor problem. Start the vehicle and let it reach operating temperature. Feel the hoses under the hood that go into the heater core. They should be close to the same temperature. If one is hot and the other luke warm/cold.... the heater core is plugged/restricted. If both hoses are near the same temperature, suspect a defective/non operational blend door motor that controls heat/cold/airflow attached to the heater box assembly

No heat in heater when idiling when reviv motor up has a little heat and heats up when ideling in traffic


Sounds like you may have combustion gasses creating an air lock in the cooling system. Or plugged heater core / radiator. Definitely a circulation problem of some kind either flow of hot antifreeze is restricted or the heater should blow very hot air especially when the car heats up so long as all the ducting and heater controls are functioning properly. If the vehicle has been overheated you more than likely have combustion gasses in the cooling system. Water pump will not work properly for combustion gasses that mix with coolant. Check to see if the coolant is beginning to get a little oily and dirty, this will indicate combustion gasses entering cooling system.

When I put the heat on in my car it blows warm air for a few seconds then goes to blowing out cold air.


The lack of heat in the car has little to do with the car's cooling system, other than the hot coolant is the heat source. 95% of all "no-heat" issues are related to heater controls and/or the heater core itself. Since you get some heat, and then it goes away, this indicates a probable vacuum leak in the heater controls. When you select heat, vacuum is directed to a vacuum motor. This motor operates a vacuum actuator that moves a linkage that moves a door inside the heater box to direct the interior air through the heater core. If this actuator has a leak, it will activate, then as the vacuum leaks off, deactivate. You probably need to have a part replaced in the heater actuator mechanism.

Low heat running & no heat at idol


I'm betting your heater core is getting plugged up. With vehicle cooled off, drain rad, and remove heater hoses going into firewall at back of engine area. Cut & connect a garden hose of proper size to one of the copper tubes coming out of the firewall. Run water through it for a while to clear it out, now connect it to other tube & do the same. Re-attach hoses, fill rad with proper coolant mix and start engine with heater (not defrost) on while you do it. Keep topping up rad as coolant goes down. Let it run for a while, and rev the engine a little every once in a while and hold it there for 20-30 seconds just to speed up the air bleed and circulation process. Leave the cap off until it reaches normal operating temperature & wait for rad fan to come on, then off 2 to 3 times to make sure all air is out of the system. Put rad cap back on & top up coolant return bottle to proper level, and check that bottle for a couple of days just in case level goes down a bit after. If you have the time when heater hoses are off, I recommend plugging one of the tubes, (bottom one) and using the hose for flushing attached to other tube, and a funnel, and filling the core with "CLR" and letting it sit in there overnight to clean out calcium build up better inside the heater core. Then drain it, flush it & re-connect next day, but that's up to you. Good Luck, let us know how it goes.
