SEALANTS


Item
 Specified sealant
Cylinder head gasket* (matching area of the cylinder block and the cylinder head)
 ThreeBond 1217G (MITSUBISHI MOTORS GENUINE Part No. 1000A923), LOCTITE 5900 or equivalent
Lower crank case*
note *: Part to be sealed with a form-in-place gasket (FIPG)

LIQUID GASKET (FIPG)
FIPG is used for some parts in the engine. It is necessary to pay attention to an application amount, application procedure and applied surface condition for this gasket to fully achieve its purpose.
Too small application amount of FIPG or the dirty surface where the FIPG is applied might cause the water or oil leakage. Too large application amount of FIPG overflows and might clog or narrow the passage of water or oil. It is absolutely essential that the surface where the FIPG is applied must be cleaned and the appropriate amount of FIPG must be evenly applied to prevent the leakage from the connected area.
FIPG used for engine parts hardens reacting with moisture in the air, and is usually used for metal flanges.
caution Reapply the FIPG with care to the followings.

  • Completely remove the old FIPG including the residue in gaps of parts.
  • Using MITSUBISHI MOTORS GENUINE parts cleaner (MZ100387) or equivalent, degrease the FIPG application surface carefully.
  • According to the FIPG application procedures, apply it accurately.

DISASSEMBLY
caution Sufficiently check that there is no residual oil on the place where degreasing is performed. If fingerprints are left, do not touch it with bare hands after the degreasing, since the oils from your fingers will harm the seal ability.
Parts assembled with FIPG can be easily disassembled without using a special method. In some cases, however, it is necessary to lightly tap parts with a wooden hammer or similar tool to break sealant between mating surfaces. Or lightly driving a smooth and thin gasket scraper in mating surfaces is useful, but full care must be exercised not to damage mating surfaces. As special tool oil pan FIPG cutter (MD998727) is set, use this tool.

CLEANING OF GASKET SURFACE
Completely remove all deposits from the gasket surface with a gasket scraper or wire brush. Make sure that the surface to which FIPG is applied is smooth.
Completely remove all the old FIPG, which might be remaining in the installation hole, the thread hole or among the components.

APPLICATION PROCEDURE
Apply FIPG in a determined diameter and continuously without break. Completely enclose the periphery of mounting holes. FIPG can be wiped off if it is not hardened. Install parts in place while FIPG is still wet. Take care not to allow FIPG to adhere to other locations than necessary locations during installation. Do not pour oil or water on applied locations or do not start the engine until sufficient time (approximately one hour) passes. The application procedure of FIPG may differ depending on areas. Follow the procedure in the body of the manual to apply FIPG.
