OVERHEATS IF SITTING STAYS OK COOL IF MOVING OVER 40 NO HEATER FA

OK HERE IS THE SCOOP..my 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 ...how 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 ...you 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

If you have a vapour lock your engine will create steam easily but the coolant doesn't circulate. Or it is possible that your impellors on your water pump have corroded

you need to check your coolant level and add coolant if you are low. if this still does not fix it you need to change your thermostat. the water is not being cooled down and the water is being ran through the engine block non stop beacuse the thermostat is stuck in the open position. for a quick fix and too keep ur engine from blowing the headgasket run your heater full blast at a stop light this will help the coolant cool down a bit.

Okay sounds like you have a clog within the system, first of all, drain the whole cooling system, run clean water thought the top of the radiator, look to see when the water comes out nice clear, replace the lower hose if you have a petcock close that, refill the top of the radiator, until it is full, start the engine, with engine running turn your heater, let the car warm a little, then reopen the petcock or loosen the lower hose and let the water draw out a little until is pouring out nice and fast, then re-close the petcock and stop the engine.
try and get 40% of the water out, and replace it with 50/50 antifreeze fill to the right point of the cars specs.

you electric fan probably isnt working with vehicle warmed up lift hood and watch temperature gauge when it starts to over heat check to see that fan is working if not it could be the fan relay or fan itself if the fan does turn on its most likley the thermostat

Radiator Fans not working


test both fand by hooking them up to a car battery first (watch your fingers) but its more likley to be the thermal switch not switching the fans on its an easy part to swop over it just scews in to the engine block with a whire plug fitted to it that is a push fit, you cant get it wrong,

replace your water pump. if youre going to do that, also do the t-stat just because it has been getting hot. refill and use distilled water with your coolant. happy holidays.

How does the fan operates, does it starts and stop. Car shuts down, red light come near milage guage, have to let car cool down and start again. Can fan cause this problem? Pontiac Gran Am 1998.


the cooling fan should come on about 105-107C and shut off about 95-97C
does the car overheat just sitting running not moving
but if the car overheats on the highway then it's not the fan
check the fan operation run the car till the gauge is over half and watch the fan
if the fan woks then check coolant level if that's ok then try a thermostat
hope

Weird humming noise & over heating while sitting in traffic


The humming is the noise the coolant makes when the car overheats and forces open the relief valve in the radiator cap and flows through the small hose to the recovery bottle., it you had all this work this done only 2 things can cause the issue, one is a problem with the cooling fan, the other is a blown head gasket, which I suspect is the problem, before you flushed the system was the coolant rusted?
