Could be,
Restricted air flow through outside of radiator,
Restricted coolant flow through inside of radiator,
Faulty fan clutch,
Missing or broken radiator fan shroud,
Faulty thermostat,
Low on coolant,
If you mean engine coolant is getting into the car, the heater core is leaking coolant causing the coolant level to drop and that causes the engine to over heat.
Lack of coolant, lack of coolant flow, air in cooling system, lack of airflow over radiator,........
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.
the reason why the coolant is spilling up over the reservoir is because the thermostat needs to be replaced because when the engine needs water the thermostat heats up from the engine and causes the springs to expant which opens a seal to allow the water throughout the engine i just realpaced the thermostat in my volkswagen
You have a coolant leak.You have a coolant leak.
Yes, If to much leaks out this will cause the engine to over heat, smoke and or stall hence the name engine COOLant :)
I would suspect the ECT (engine coolant temperature) sensor is at fault.
Many possible causes... coolant level, thermostat, head gasket, water pump, fan not working
If the coolant reservoir can not maintain the proper level of coolant, it is possible the engine could over heat when the level drops.
If there is coolant on an engine, it is likely a seal or a hose is leaking or broken. It should be repaired immediately or the engine may seize up and quick working.
Fill your coolant reservoir and the light should turn off. Do it soon or your engine may over heat.
It means the engine is overheating. Possible causes are, thermostat stuck in closed position, low of coolant, cooling fan not functioning, blown head gasket, clogged radiator inside or outside, or water pump not functioning properly.
