    Check the oil for water, if water is in the oil it will look foamy, have the cooling system pressure tested.

If you have a little white smoke out of your exhaust, it might be a head gasket.

Does anybody have a video link on how to flush the cooling system on a GM 3.1L SFI OHV 6cyl motor? I need a vid for this particular motor cause mine is still overheating & i have looked everywhere.


flushing a cooling system is the same method as any other motor

do it without the thermostat fitted
or water pump opening

sacrifice an old radiator hose to adapt a garden hose fitting
for radiator flush

air in system fix
your thermostat housing has no air bleed valve
no top radiator cap

old school way
heater on full
run motor till thermostats fully open
burp radiator hoses
wait till water is running up into over flow bottle without bubble
replace cap
turn off heater
correct level in over flow bottle

why still over heating
you fitted everything i would have ... yet still overheat
possibles
leaking inlet manifold gaskets
hose clamps loose
cooling fans spinning too slow
thermostatic fan switch faulty
aluminum radiator is a big one
air ..fins bent or some water channels blocked

or possible head gasket leak

White smoke coming from exhaust car running fine no overheating where is white smoke coming from and or there a quick fix


White smokee is normally a sign of coolant getting into a combustion chamber, due to a head gasket, leaking intake, or a crack in either. Check your coolant level! Running it with this problem will destroy your engine. I would get it pressure tested.

Temperature control


The radiator cap is at the radiator where you refill the radiator with coolant. Unless it is leaking and you hear a hiss. It may not have anything wrong.Neither will the water pump.If the water pump is bad. It has a small hole that will make it start leaking .Check the engine for leaks at the intake or the water pump.You will know where it is leaking. When the thermostat was removed and hopefully replaced , did you bleed the system ? The system has to be bled to remove air pockets. Or the engine will overheat again. Also check that the radiator fan or fans is turning on . If not you may need to replace the temperature control sensor.(TPS)

Sounds like you may need a new Thermostat.

Get a Haynes or Chilterns manual and a new Thermostat for the carfrom a car parts place like Autozone. Its normally a simple opperation to change it.
