• Page 7: Sealant (Fipg)

  00-7 OVERVIEW SEALANT(FIGP) Sealant (FIPG) Sealant is used on many parts of the engine and gearbox. The using of sealant is for the purpose of adequately sealing, therefore, much attention should be paid to the dosage, position and the surface of sealant. Insufficient dosage of sealant may result in leakage, while superfluous dosage of sealant may result in the overflow of sealant and jam the passage of water or oil, or narrow the passage.
