Question about 1998 Ford Taurus

Overheating and no heater while doing so

I just changed out my thermostat thinking it was the cause of my car overheating but it seems to still be doing the same thing. At idle it does not overheat but with any throttle involved it heats up and cools back down very slowly when i let off the throttle. The heater is not working through all this and for some reason my oil light is barely flickering in the dashboard.

Replace the oil sending unit,and see if the light will go off.Next fill radiator up full,and or reservoir.Then bleed the cooling system of air.This will cause the engine to run hot,and no heat inside the car.The best way to bleed it is to,fill reservoir up full,to top,run engine and cut engine off before it gets hot,about 218,then wait about 30 to 45 minutes and check level in reservoir.It should have dropped.Refill,and repeat untill engine runs cool,and cooling fans cut on,and cut off by themselves.Do this with ac and defrost off.I hope this will help.

How does a heater cause overheating?

Here's a thought. If you use the a/c it turns on a radiator fan. If you changed it over to heat the a/c fan shuts off. So if the cooling fan was broke all a long then you wouldn't notice until you turned the heat on. How did I think this up. I owned a Ford once.

Overheating grande vitara 2008

I shouldn't be blocked because it is pretty new. The systems are usually good for 10 yrs or so before they start getting gunked up. I would think it is either the electric fan or the fan clutch (whichever you have) could be out and it isn't cooling the engine. Also, you could have air in the system which could cause the rest of the coolant to not circulate. Check for an air bleeder valve near the top of the engine, usually near the thermostat housing.

Do both cooling fans on 1999 lincoln continental have to work to keep from overheating

I'm not sure the thermostat is the problem. If the thermostat was stuck open the engine would not warm up and also not overheat.
If its stuck closed, the engine would warm up as well as the heater, then continue to the point of overheating.
If the cooling system is low on liquid coolant, or the water pump is not working, the coolant will not flow thru the heater and the sensor may not know to turn the fans on.

My 1999 Chevy Malibu runs hot? It started when it overheated. We changed the thermostat, then water pump, then temp sensor gauge and the temp gauge goes high but only when the heater stops blowing hot...

Air pockets will make the guage do that, and also cause your heat to come and go. Also, a poor radiator, as in rotting, or plugged up, will cause high temperature issues.

I have a 2000 hyundai sonata. There is no heat at all and it's not overheating which I think eliminates the thermostat being bad. What do you think the problem could be?

either the flap on teh heater under the dash or the core needs a flush with the garden hose ,but the most likely cause is the flap operating cable if fiyyed or the vacumn operating device ,Iam not sure if this model is cable or vacumn though but i think the fault lies here more than it being blocked

There was water on the passenger side and now the car is overheating is that the heater core? There is still heat coming out of the vents.

I have a 2000 camaro as well, and it seems that is giving me the same problems... in addition to what your is doing my car overheated on the road, and lost power. I replace the sensors, flushed my radiator, the thermostat, I cannot remember if I changed the water pump... But I think at this point in time the only solution is to replace my engine.

1994 Honda Civic LX\overheating within 2 mile drive

Remove and raise upper hose at thermostat end and remove lower rad hose.
Fill rad with a hose and watch for flow from bottom rad hose and/ or bottom rad hose connecton.......water should fall though rad easily.
Honda rads are cheap.....any restriction....replace rad.

Remove thermostat....fill thermostat housing with hose and watch for water flow at bottom rad hose.
Flush good.

Remove heater hoses.......flush back and forth until a good flow is present "With heater control set to hot" if no or poor flow....replace heater core.

Stop leak can plug everything.

Also.......not likely causing over heating....but your mileage,if you do not know if the timing belt has been changed.....CHANGE IT NOW!
Water pump is optional at this mileage.

Engine overheating audi 4.2 a8 1999

I would have the cooling fan checked, and have the thermostat changed. An overheated thermostat (overheating caused by something else) will cause problems in the future.
