Engine sealing is done by gaskets and seals.

Leaks are both annoying and potentially lead to engine damage and failure.

Engine sealing, gaskets and seals are essential to that make sure that;

  • Oil
  • Fluids
  • Coolant
  • Air

Do not mix or leak out from your engine.

Consequently, Engine gaskets and seals are part of an engine that most vehicle owners do not anticipate having to replace. Of course, the need for gasket replacement depends on how long the vehicle has been in use. So, The purpose of a gasket is to seal engine components and prevent leaks. Engine leaks are one of the worst problems a vehicle can have.

Typically, a gasket will not begin malfunctioning until a vehicle has reached at least 60,000 miles. As a result, Coolant leaks are a common sign that a gasket may need replacing.

There are also other causes for coolant leaks like;

  • A leaky radiator cap
  • A hole in the radiator
  • Water pump leak

Engine Gaskets And Seals Must Meet Strict Standards

  • Must seal system fluids
  • Chemically resists system fluid to prevent serious impairment of its physical properties
  • Deforms enough to flow into the imperfections on the gasket seating surfaces
  • Withstands system temperatures without serious impairment to performance properties
  • Is resilient and creep resistant enough to maintain an adequate portion of the applied load
  • Has sufficient strength to resist crushing under the applied load
  • Does not contaminate the system fluid
  • Does not promote corrosion of the gasket sealing surfaces
  • Is easily and removable at replacement

Important Note;

When cleaning mating surfaces prior to the installation of new gaskets, avoid the use of any hard metal scraper which can gouge or scratch the surfaces. This is especially true when dealing with aluminum surfaces such as cylinder heads, timing covers, oil pans, water pumps, etc. As a result, Aluminum alloy used on production engines is relatively soft and can easily be damaged with the careless use of a steel scraper.
