Engine overheats When a car or truck overheats idling, in town, on the highway, while towing, etc. it is important to find out the reason to prevent engine damage. First, with the engine cold, make sure the radiator is full of coolant; if it is low, fill it and keep the radiator cap off while the engine idles to insure all air is bled out of the system ( air trapped in the system can cause overheating also). Check the coolant level daily; if the coolant goes down without visible leaks, it may be a head gasket starting to leak which will also cause the heater to blow cold air due to the lack of available coolant. If the coolant stays full, but the car continues to overheat, the next step is to replace the thermostat in the engine and flush the cooling system if that has not been done over the last few years.Buy a thermostat at a parts store and a PRESTONE flush kit which has excellent directions on the package.After completing these steps and the vehicle still overheats, have your cooling fan sensor/switch ( if equipped)checked out to insure it is coming on. Water pumps are seldom the cause as they are mechanical and will continue to work until their bearings give out. Finally, the radiator itself is often the problem as it tends to build up corrosion internally which prevents it from transfering engine heat to the coolant. Remove it and have it 're-cored'. One of these steps will solve the problem.
change the water temp sensor
Engine overheats, no power, or just won't start. Transmission won't shift right.
temperature sensor, fan relay, or fans themselves are bad.
check you water (coolant) level, make sure thermostat is working, radiator leaks, sensor problem
P1780 Push - Pull Sensor Mal, could you please explain what the push - pull sensor is please?
please elaborate a little more. you talking an 02 sensor? a knock sensor? a M.A.P. sensor??
How are you verifing the engine temp? I would suspect one of 2 things. possibly it is not overheating, the temp sensor is causing faulty gauge readings, in which case change the sensor. If it is overheating check to be sure the exhaust sytem is not blocked, possibly bad catalytic converter.
where is the bank1 o2 sensor at and how do i change it please i need your help
Not sure what an "AIT" sensor is, please explain.
What makes you think it's the temp sensor? It sounds more like a stuck thermostat, faulty water pump or plugged radiator.
iat sensor? Please describe this device, never heard of iat sensor. Post again
please help
