OILPAN
Scraper '""'\
SEM3508Removal

1. Drain oil.
2. Remove oilpan using toolasillustrated.
1) Insert Toolbetween oilpan andcylinder block.

• Do not drive sealcutter intooilpump orrear oilseal
retainer portion,oraluminum matingsurfaces willbedam-
aged.
• Do not insert screwdriver, oroil pan flange willbe
deformed.

2) Slide Toolbytapping itwith ahammer, andremove oilpan.

Installation
1. Before installing oilpan, remove alltraces ofliquid gasket
from mating surface usingascraper.
• Also remove tracesofliquid gasket frommating surface of
cylinder block.
• Besure liquid gasket is3.5 to4.5 mm (0.138 to0.177 in)
wide.

Use Genuine LiquidGasket orequivalent.
