Introduction
A head gasket is a crucial part in your vehicle's engine. It plays a vital role in maintaining its performance and reliability. When it fails, it leads to engine problems and costly repairs. It’s important to know what a head gasket is, how to spot failure symptoms, and when to replace it. This will save you from damage and expenses.
What is a head gasket?
A head gasket sits between the engine block and cylinder head. It seals the combustion chambers and stops coolant and oil from mixing. Its main function is keeping the pressure needed for combustion. This is to make sure the coolant and oil flow through the engine without leaking into each other. It’s a seal that’s essential for the engine’s longevity.
