Defective radiator cap?
Fan temperature sensor defective?
If the pump is not circulating coolant insure that the thermostat is not stuck closed. If the thermostat is ok then the pump will have to be replaced.
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.
If your rasiater has allot of sediment in it, or your thermostat is stuck, or malfunctioning your emgine would overheat without affecting your coolant level. Sediment, because the coolant is moving and at level, but radiater is too comtaminated to function properly. if the Thermostat is malfunctioning, it wont open and allow coolant to flow and cool the engime
Did you replace the throttle body warming plate? To bleed properly run the engine THEN undo the coolant cap and top up to full - do not undo when cold as the expansion tank is lower than the head of the radiator, always use orange extended life coolant Dom www.landroversalvage.ca
There is usually an ECT (engine coolant temp) sensor and a CTS (coolant temp sensor) located around the thermostat housing mounted in the intake. One sends coolant temp to the guage, the other sends temp to computer.
Usually it doesn't work like that. You basically need to check why it has been overheated. If it was because of you didn't have enough of coolant than you need to add coolant and check for leakage. If it happened because of the thermostat failure, you need to replace the thermostat and then drive the car. Other things might cause overheating too. PS: You have to be careful when you are dealing with an overheated engine.
You can uninstall thermostat and install new thermost under air filter and look coolant hose by sensor gang. I did my own car.
Check your radiator and make sure it has coolant in it. Thermostat might also be stuck.
Thermostat fail to open. Waterpump is on the deathbed. None, or not enough Anti-freeze in radiator.
it could be that you've put too much coolant to percentage of water in
You need to check coolant temperature sensor and the water pump.
Coolant at proper level? System air bound and needs to be purged? Water pump not circulating coolant? Defective thermostat? Collapsed radiator hose?
