1 Answer


OK HERE IS THE heater fan stopped working and the car ran very porrly all of a sudden when cold in the monring ...then it overheated ...i had replaced the thermostat (bmw part) 6 months ago anyway took the thermostat out completely and even in the sub 32degrees weather 24/7 here the last 2 weeks the car still will over heat if sitting still but wont if cruisning over 40mph. in sub freezing weather is the thermostat that important?? also stupidly never considered the water pump as the problem ... the radiator builds up pressure when hot alright (look like old glory steaming thru the overflow area) i plan on putting the thermostat back in it today do i tell if waterpump is problem?? makes no noise that i can hear ...also what about the heater fan ?? unrealted ?? resistor? help!!

    There doesn't appear to be any other indications of a hea gasket problem ...(or a cracked block) Standing there trying to figure out what the problem was i discovered that none of my fans kicked on at all know the two fans that **** cold air through the two holes in the front of the car ?? with no thermo and no fans kicking on at all ....if that car were to sit for very long it would over heat ?? yes?? Also I think that after reading a couple of other posts here that my heater fan issues may be a fuse,.... which I plan on checking this morning any thoughts gurus?

You can check if the water pump is working by feeling the top rad hose , if it is hot it should circulate into the rad and the rad should be hot at the top and cool at the bottom if the pump is faulty there will be no circulation of hot coolant into the rad. I suspect your head gasket might be blown if you are getting pressure built up in the rad. in that case you will need a new gasket and have your head skimmed

My cars temp suddenly ran in the red (hot) so i turned the heater on to cool it down and the heater would only blow cold air what could this be?

"ran hot and the heater only blows cold air"

First thing that came to my head reading this is check the coolant level.

Not Overheating, Smells like really hot antifreeze after I drive, a/c ok heater heats but when stopped air gets cold...stummped..thermostat?, Leak?

check your hoses and make sure its not getting low because when it gets low the hoses can get hot enough to expand and spit out antifreeze without overheating

Heater stopped working suddenly, fuses are okay.

if your fan (blower motor) stopped working, more likely is the blower motor resistor, is locate it close to the blower motor. if the blower motor is ok, maybe your heater core is cloged.

It over heated no leakage in the over flow, fluid is moving, no leagage in the rad however when i go to rev up the car i hear like a gurgling sound comming from the dash could it be the heater...

if your heater core is bad you will more than likely have coolant on the carpet on the passenger side floor. also this car uses a shared fan. the fan not only cools the radiator but also makes sure the a/c is blowing cold. the fan motor may be bad which is why you overheated. a sign the fan morot isnt working is the a/c stops blowing cold air when the car is stopped at a red light, drive thru, ect. since the car overheated you may want to double check that you havent cracked the plastic tanks on the side of the radiator. has the low coolant light come on?

Heater blowing hot then suddenly blows cold and engine overheats. Intermittent problem. After engine cooled may overheat again with heaters blowing cold then suddenly heater blows hot again and...

I have written a tip on this.
You may have a couple of problems. I would first replace the thermostat, and make sure you have the proper coolant(ant-freeze) level.
Please let me know how it goes and if you need further help I am here.

Overheating again

The heater stopped working because there was no coolant in it. Your real question is where is the water going.

Have the cooling system pressure tested to be sure you have no leaks. You said you had the radiator flushed, I suspect some of the tubes are blocked, it should be dissassembled and rodded then cooked out. Not just flushed. You problem is in traffic, low speed. The car starts to over heat, it blows the water out of the overflow, the level is down, the heater stops working, then you are out of water in the engine and overheating.

BTW ground the wire that goes to the warning light sensor and be sure it lights the warning light. If htis is the case the sensor is bad. I assume when you turn the key on but before starting the light does work then, correct? That means the bulb is ok, that does not check the sensor.

Good Luck!
