Yes, If to much leaks out this will cause the engine to over heat, smoke and or stall hence the name engine COOLant :)
You have a coolant leak.You have a coolant leak.
why does the coolant only leak when engine is off on my 1999 grand am?
A bad freeze plug will leak coolant and cause the engine to overheat.
A bad radiator is a radiator that is leaking or clogged. If you are loosing coolant then you have a leak that should be easy to find if the leak is at the radiator. If it is clogged your engine will overheat.
bad hose, radiator leak, leaking into engine.
if it only leaks during starting then thats really strange. but if you have a leak some where, then when you turn engine over it will turn water pump that will pressurize engine. if it leaks while running the engine then be careful and try to find source of the leak, it is most likely a bad seal, having bad seals is really really bad, it could leak into oil, not good for lubrication, find the source of your leak, or if its small enough leak, then put some stop leak threw it i wouldnt trust it farther than you can throw it, but if it works then i would suggest replacing all of your coolant to be on the safe side
Head or head gasket leak
Bad thermostat, Low on engine coolant--( coolant leak ) Cracked head, Leaking head gasket,
Make sure it really is low on coolant by checking the coolant when engine is off. If the level is up to par, then the sensor may be bad.
No. A bad water pump can make a rumble noise and leak coolant which may lead to the engine overheating.
yes, especially if the leak is causing coolant to leak, you can run out of coolant. then overheat.
If it is an internal leak the coolant will end up in the crank case mixed with your oil and it will ruin the bearing/engine - if external leak then the engine will overheat when it runs low on coolant, and blow your head gasket
