60 Second Problem Solver

There’s more than one way to identify a car leak. From head gasket failure to problems with your water pump, diagnose your car leaks in 60 seconds with this handy list of symptoms and solutions.

White Smoke From The Exhaust

This is actually steam condensing as it gets burned off by the engine. You may also see blue smoke, for a different reason. Either way, it’s likely your car is suffering from head gasket failure, and you need to fix the problem, fast.

Solution: Add K-Seal ULTIMATE to the cooling system. For more information on why this might be happening, check out our in-depth articles:


Bubbles In The Header Tank

This suggests that combustion or exhaust gases are leaking across the head into the coolant due to a head gasket failure. In extreme cases this may even cause the coolant to overflow.

Solution: Add K-Seal ULTIMATE to resolve this issue but be sure to read the full instructions.


Engine Overheating

A coolant leak will lead to the engine overheating because there isn’t anything to cool it down.

Solution: Add K-Seal so it can find the leak and plug it.

Puddle Under The Car

This could be a radiator leak or a split hose causing coolant to leak out of the engine onto the ground underneath.

Solution: If it’s a radiator leak then add K-Seal. If it’s a split hose then you’ll need to get the hose replaced or try Kalimex QuikTape.
