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.
Then, how do I know if there is coolant in my cylinder?
Coolant in the cylinders will cause:
- White smoke coming from the tailpipe.
- BUBBLING IN THE RADIATOR AND COOLANT RESERVOIR.
- unexplained coolant loss with no leaks.
- Milky white coloration in the oil.
- Engine overheating.
Additionally, what would cause exhaust gas leakage into the cooling system? If there is a hole in between your combustion chamber and the cooling jacket in your head gasket, each time the piston pushes exhaust gas out of the combustion chamber into the exhaust system some exhaust gas will also be pushed into your cooling passage.
Keeping this in consideration, how do you check compression in coolant?
To test your cooling system's integrity a garage can add a pressure gauge to your cooling system, then pressurize it using compressed air. Once the air source is removed you can watch to see if the pressure in the system holds constant or decreases over the course of a few hours.
Why is my coolant low but no leaks?
When you are losing coolant but no leak is visible, several parts could be the guilty party. It could be a blown head gasket, a fractured cylinder head, Damaged cylinder bores, or a manifold leak. It could also be a hydraulic lock.
