If car still overheats after changing the thermostat the water pump the headgaskets and the radiator what else would cause it to overheat?
From what you describe it sounds like you might have an air lock in your cooling system. I would recommend that you bleed any and all air out of the cooling system. The bleeder valve is located on top of the engine. Once engine starts to overheat or when you can hear bubbling back into the overflow bottle, turn car off and open bleeder valve. If you see bubbling you have air in your system. Bleed the system a couple of times and see if this helps.
if it still overheats after that like my BMW 318 does you could be looking at a crack in the engine as i think that's my next option
but also check or renew your heater matrix and temp sensors and use a rad leak in your rad even though its a new one as the leak could be in the engine so might seal it
generally if an engine overheats, but then does not overheat when heater is turned on, is a good indication that the engine thermostat is stuck and needs replacing
Try replacing the thermostat.
Assuming it did not overheat before you replaced thermostat and water pump you may have installed the thermostat backwards. It is also possible the cooling system wasn't refilled properly and was air bound.
check your fan clutch if its weak it will overheat
you need to burp the cooling system
replace upper radiator hose and install a new thermostat. see what happens. or turn it on without the thermostat for a while and see if it still overheats.
theyre maybe an air bubble in the block causing it to overheat,or it could also be a bad water pump
The thermostat may be installed backwards
You have a blown head gasket.
Check if the thermostat is working properly. See if the top of the radiator is very hot when the motor starts to overheat, if it isn't hot then chuck out the thermostat or better still replace it.
A bad thermostat can cause an overheat. A bad temp sensor can show an overheat when the temperature is normal.
Mine was caused by a blown head gasket. Could be a defective thermostat or a plugged radiator too. Would need more detail about when it overheats and how you know it is overheating to give a better answer.
if the pump and thermostat have been replaced on a 2001 malibu and it overheats and the heat doesnt work now but the air does. do it need bleeding still , will air in the line still cause that problem...
you have a phase 1 ej25 engine with blown headgaskets...don't continue to overheat it...get it fixed pronto
There could be many reasons. Not enough coolant or bad flow, faulty thermostat, low oil. If the coolant freezes then it will overheat. If your car continues to overheat then you should have the coolant flushed and thermostat replaced.
Generally, if your car overheats with the proper level of antifreeze, either your water pump has gone bad (not circulating fluid), the thermostat is stuck, or your radiator is clogged up inside. -NAPAman
You may have the thermostat in backwards. The spring side of the thermostat faces into the engine.
There are several things that can cause your 1992 Mitsubishi Eclipse to overheat. A malfunctioning water pump or a blown head gasket should be the next things that are checked.
You have not bleed the air out of the system after you installed the t-stat, causing the heater not to work and the engine to overheat. Use a coolant filler that screws into the radiator and get the air out
Either the thermostat was not the problem, or you put it in backwards.
why does my Honda civic overheat and doesn't heat at all
thermostat is more than likely stuck shut from the overheat. Have to be changed.
No beaxause it can overheat and catch fire No beaxause it can overheat and catch fire
