GENERAL

For oil change procedure, refer to LUBRICATION
in the appropriate VEHICLE SHOP MANUAL.

PROCEDURES

ENGINE OIL PRESSURE

NOTE: Depending the oil pressure switch, the
threshold value to send a signal of low oil pressure
may vary from a minimum of 180 kPa (26 PSI) to
a maximum of 220 kPa (32 PSI).
NOTE: The engine pressure test should be done
with a warm engine and the recommended oil.
Use oil pressure gauge (P/N 529 035 709) and
hose adaptor (P/N 529 035 652) and install where
shown. A 1/8 NPT pipe extension may ease the
installation.
