Low coolant can sometimes cause a head gasket on your engine block to blow. If this happens, you may notice smoke emitting from the engine or tailpipe, a loss of power, engine knocking sounds, or decreased efficiency.
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.

What does a spark plug look like if you have a blown head gasket?
Inspect each spark plug for failure signs. Dark sooting from misfiring, water droplets, brown spotting, and rust around the threads are all signs of head gasket failure. In some cases, where severe gasket failure has occurred, condensation and moisture will accumulate on the plug boots.
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. You may have to check your exhaust to see if white fumes or smoke is emanating from it. It is possible for low or no coolant in the engine to cause your car to shake.
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.

What causes coolant to drop from the radiator?
Overflow Reservoir Most overflow reservoirs come equipped with a small tube that allows the coolant to escape if the engine gets hot enough and the coolant expands past the full mark on the overflow reservoir. Small pinhole leaks in the radiator will cause coolant fluids level to drop.
