PRECAUTION
PRECAUTIONS
When working with FIPG material, you must observe the following.
wUsing a razor blade and gasket scraper, remove all the old packing (FIPG) material from the
gasket surfaces.
wThoroughly clean all components to remove all the loose material.
wClean both sealing surfaces with a non±residue solvent.
wApply the seal packing in an approx. 1 mm (0.04 in.) bead along the sealing surface.
wParts must be assembled within 10 minutes of application. Otherwise, the packing (FIPG)
material must be removed and reapplied.
If the vehicle is equipped with a mobile communication system, refer to the precaution in the IN sec-
tion.
