Can low coolant cause a misfire?
Coolant Problems Internal coolant leaks can foul a spark plug and cause a misfire. Unfortunately, it also means that drivers will run a vehicle with a coolant leak for several thousand miles while the plug becomes slowly fouled.
What are the symptoms of low coolant?
Warning signs of low or no coolant/antifreeze: Rising temperature gauge: A rising temperature gauge may be due to an increase in your engine’s temperature. Automatic engine cut-off: Most modern cars are equipped with an automatic engine cut-off feature. When coolant is low, your engine will start to heat up.

Why does my car shake when there is no coolant?
The coolant system in a car is typically a closed-loop and if there is an issue with the car head gasket, the coolant will automatically leak into the combustion chamber.

What causes fluid to leak out of the radiator?
A malfunctioning radiator cap can be the cause of fluid leaks in the coolant system. Never take a radiator cap off after the car was just shut off, as the system is under pressure. Wait until the radiator is cool to the touch before removing the cap. Replaceable caps are available from auto parts stores for a small cost.
