What is the purpose of a de-carbonizing kit?
A de-carbonizing kit, often called a head gasket set, contains the necessary seals and gaskets for removing the cylinder head to perform service. This includes tasks like cleaning carbon deposits, servicing valves, or replacing a failed head gasket.
When should the gaskets in this kit be replaced?
These gaskets are designed for single use and must be replaced whenever the cylinder head is removed for maintenance or repair. Signs that service is needed can include loss of compression, oil in the coolant, or external exhaust or fluid leaks from the head/block joint.
Are special tools required for this job?
Installation requires standard mechanic's tools, a quality torque wrench, and gasket scrapers. We strongly recommend consulting your engine’s service manual for a complete tool list and step-by-step instructions.
