Oil Filter/By-pass Filter, Change
The oil filter and by-pass filter must be replaced at
every oil change.
Deposit the old filter at a waste management facility.
WARNING!
Hot oil and hot surfaces can cause burns.
1 Put a suitable container under the filter to collect
any spilled oil.
2 Clean the filter bracket.
3 Unscrew the by-pass filter (1) and the oil filter (2)
with a suitable filter puller.
4 Check that the mating surfaces on the filter bracket
are clean and that no remnants of the old gaskets
are left.
5 Moisten the gaskets on the new filters with engine
oil.
6 Screw on the filter by hand until the rubber gasket
touches the filter bracket mating surface. Then
tighten an additional 3/4 turn.
7 Start the engine, run at low idle, and check that no
leakage occurs. Check the oil level after the engine
has stopped.
