  • Contains a few sub-sets in each group

  • Engine overheating
  • Bad OEM gasket
  • OEM materials not best suited for your vehicle
  • Pre-ignition or detonation problem
  • Installation errors

What are the Symptoms of Failure?

  • Engine overheating
  • Exhaust gases in the radiator
  • Engine running poorly – skipping, hesitating or lack of power
  • Coolant in the oil – engine oil will resemble chocolate milk
  • Excessive pressure in the crank case

What are the Implications of Failure?
