Thermostats go bad everyonce in a while. To check feel upper hose ( PROTECT HANDS AND FACE) see if water is flowing when car is hot, it not easily replace cheap thremostat, if water is flowing could be water pump. Leave this procedure to mechanically inclinded friends or shop.
Low coolant? Cooling system airbound? Low coolant? Cooling system airbound?
Low coolant? Cooling fan not working?
It can prevent coolant flow, which can cause a catastrophic overheat.
If coolant is up to proper level and cooling fans are working - should not overheat
Coolant doesn't go through the cooling system, and the vehicle will overheat.
water pump or cooling fans or thermostat low coolant
lack of coolant . no cooling fan operation, low engine oil, improper coolant mixture, thermostat stuck, debri on radiator , restriction in cooling system.
cools the engine. without a fan, the car will overheat and the coolant will boil. the fan controls this from happening by cooling the coolant as it passes through the radiator.
Blocked radiator, low on coolant, stuck thermostat, air in cooling system
Low coolant? Radiator plugged or restricted? Cooling fan not working? Water pump not circulating coolant? Thermostat not opening? Cooling system airbound?
Possible reasons for overheating: Low or out of coolant Clog in cooling system Thermostat failure Cooling fan not operating water pump failure
The engine could overheat and destroy itself. It's a very bad idea to drive a car with no cooling system.
