Why does coolant bubble in the radiator?
Bubbles in the Radiator. Besides allowing coolant into the combustion chamber, an internal head gasket leak allows exhaust gases into the coolant. This can cause bubbles to be in the radiator or coolant reservoir making the coolant look like it’s boiling even when it’s cold.
How to identify a head gasket leak?
If there are no other cooling passages or hoses near the head gasket you may be able to positively identify the leak as a head gasket leak, but if there are other cooling passages nearby, you may need to add a UV dye to the coolant then watch the head gaskets with a UV light to positively identify the leak.
What is the head gasket?
The head gasket forms a seal between the engine block and the cylinder head.
