LIQUID GASKET APPLICATION PROCEDURE

a. Use ascraper toremove alltraces ofold liquid gasket from
mating surfaces andgrooves. Also,completely cleananyoil
from these areas.
b. Apply acontinuous beadofliquid gasket tomating surfaces.
(Use Genuine LiquidGasket orequivalent.)
• For oilpan, besure liquid gasket diameter is4.0 to5.0
mm (0.157 to0.197 in)for SRengine and3.5to4.5 mm
(0.138 to0.177 in)except forSRengine.
• For areas except oilpan, besure liquid gasket diameter
is 2.0 to3.0 mm (0.079 to0.118 in).
c. Apply liquidgasket toinner sealing surface aroundhole
perimeter area.
(Assembly shouldbedone within 5minutes aftercoating.)
d. Wait atleast 30minutes beforerefilling engineoiland
