air trapped in your coolant system. take the radiator or coolant recovery tank cap off if you don't have a radiator cap. Take it off when the engine is cold. Start and run the engine at idle with the cap off. Keep adding coolant if you see the level go down. Continue to do this until no longer see any drop in the fluid level. If your fluid does not move, then your water pump is the culprit and not moving the coolant out of the engine.
Waterpump, thermostat, radiator, radiator hoses.
Bad head gasket or... Crack in exhaust port in head. Check exhaust for presence of antifreeze smell or exhaust gas in radiator.
ah.......radiator??
It changes the freezing and boiling point.
The most common cause of overheating is a thermostat stuck in the closed position. However, other causes are: faulty water pump, clogged radiator, clogged hose(s), coolant leak or a broken drive belt. I had a 1987 legend with around 160K that was overheating. Antifreeze would boil out of the overflow. I changed my radiator and it fixed the problem.
Start with the cheapest fix first. Replace the radiator cap. If still overheating replace thermostat. Make sure you have a 50/50 mix of antifreeze and water. Lastly if all else fails, check for a plugged or faulty water pump and or radiator.
things to check for is thermostat, check water circulation in radiator (possible bad water pump), radiator could be blocked, and most of all make sure all fluids are up to spec. (oil and antifreeze)
First thing you should check is the antifreeze level. If that is fine, replace the thermostat. If it still over heats after the thermostat, then most likely you need to replace the waterpump. If your antifreeze is low, check for leaks, the radiator, hoses, heater core, and water pump. If the water pump is leaking, that is your problem, replace that and thermostat all in one.
low radiator fluid or a possible bad thermostat.
Check the fan clutch, it may not be working properly.
the thermostat will be under the THERMOSTAT HOUSING, which is where the TOP radiator hose fits on ie(radiator to thermostat housing) this keeps the engine at an OPTIMUM temperature BUT can be A cause of OVERHEATING IF malfunctioning
Replacing a bad water pump can help to stop a motor from overheating. Hopefully that was the cause of the overheating. If it does not stop the overheating, try replacing the thermostat. Make sure you have the proper mix of antifreeze and water, the radiator filled with it. Check the level of coolant FIRST. Next, the hoses, and third the thermostat. Then, disconnect a hose and see if, by starting the vehicle, if there's water pressure. If not, its water pump time!
