Heat, lack of lubrication, or coolant in the cylinders or oil pan.
Have you checked the water level in the coolant expansion tank, if low this will not heat up the car. If level ok maybe thermostat is stuck Have you checked the water level in the coolant expansion tank, if low this will not heat up the car. If level ok maybe thermostat is stuck
Could be low on coolant or a sticky thermostat.
Usually in cold weather climates it means that your cars coolant is freezing up. It will cause the engine temp to get real high as the coolant does not circulate which then also causes you to not have any heat.
As the engine coolant heats up, the coolant expands, so the coolant needs a reservoir or expansion tank to flow in and out of as needed.
Coolant sensor is shot. Replace with new one.AnswerThe reed switch may be stuck. My 98 Grand Am coolant tank ran dry last week when my lower intake manifold gasket started to leak. Fixed the leak and refilled the tank only to see the coolant light still on. Tapped the switch/sensor on the bottom OS the tank with a rubber mallet so the magnetic float could loosen up and float back up. Sure enough, turned on the ignition and light was out.
Have you bled out the cooling system? Put the heater heat control to max heat, fill the header tank with coolant then start the engine and let it run with the tank cap off till it reaches normal temp (cooling fan cuts in). Dont worry about any coolant being ejected from the header tank that's just the air bleeding out, just make sure there is always coolant in the tank topping up as nessasary. When the engine is up to temp check that there is heat at the demisters. If not bring the engine to a fast idle (1500 rpm) whilst checking for heat at the demisters. Once you have heat at the demisters return the engine to idle, top up the header tank to max mark if nessasary and replace cap. Job done.
Add it in the overflow tank up to the max line.
The most common cause of a blown head gasket is an over heating engine. Low coolant or coolant not circulating through the engine causes the engine to heat up and the gasket to fail.
your cars thermostat could be broken, making the coolant+engine not heat up, sucking the coolant from the expansion tank because its cold and giving your car a rough idle cause it has a hard time warming up
When all the coolant in the radiator and coolant tank heats up the volume will increase and force it's way through the weakest point which would probbaly be the cap on the recovery tank - if you have filled the recovery tank to the maximum you had better take half of it out.
The combustion of fuel inside the motor is what produces heat. The higher your RPMs, the faster this process occurs, and the quicker your motor will heat up. If your cooling system isn't preventing the vehicle from overheating, it could be due to low coolant/no coolant, or it could be due to a bad thermostat.
