Coolant Filter (5) - Check the DCA4 concentration
and replace the coolant filter at every oil and filter
change interval. Refer to Section 210-0000, COOLING
SYSTEM.
Crankcase Breather - Check and clean the
crankcase breather hose. Remove the breather hose
and check internally for obstructions or sludge buildup.
Clean or replace breather hose as necessary, to
prevent excess crankcase pressure buildup.
Drive Belts - Check belt tension and adjust if
necessary, as described under 'Drive Belt Adjustment'.
Air Intake System - Inspect the air intake piping for
cracked hoses, loose clamps, or punctures which can
damage the engine. Tighten or replace parts as
necessary to make sure the air intake system does not
leak.
DRIVE BELT ADJUSTMENT
Note: Position the vehicle in a level work area, apply
the parking brake and switch off the engine. Block all
road wheels and place the battery master switch in the
'Off' position.
Measure the belt tension in the centre span of the
pulleys using a belt tension gauge. The belt tension
should be within the following limits:
Fan Belt Tension
Belt Tension 'New' - 890 N (200 lbf)
Belt Tension 'Used' - 360 to 710 N (80 to 160 lbf)
Alternator Belt Tension
Belt Tension 'New' - 670 N (150 lbf)
Belt Tension 'Used' - 270 to 530 N (60 to 120 lbf)
Note: A belt is considered 'Used' if it has been in
service for 10 minutes or longer. If the used belt
tension is less than the minimum value, tighten the belt
to the maximum value.
An alternative method (deflection method) can be
used to check the belt tension by applying 110 N (25 lbf)
force on the belt between the pulleys. If the deflection
is more than one belt thickness per foot (305 mm) of
pulley centre distance, the belt tension must be
adjusted.
Clean the area around the lube oil filter head and,
using strap type filter wrench, remove lube oil filter (4).
Discard lube oil filter (4) if it is not required for a failure
analysis. Clean the gasket sealing surface of the filter
head.
Note: The 'O' ring can stick on the filter head. Make
sure the 'O' ring is removed and discarded.
Note: Fill the filter with clean lubricating oil prior to
installation. The lack of lubrication during the delay
until the filter is pumped full of oil is harmful to the
engine.
Apply a light film of clean lubricating oil to the gasket
surface of the new filter and install the filter on the filter
head as specified by the filter manufacturer. The
tightening instructions are normally printed on the
outside of the filter.
Note: Mechanical tightening of the filter is not
recommended and may result in seal and/or cartridge
damage. Tighten filter by hand only.
Check and clean the engine oil drain plug threads and
the seal surface. Install and tighten the drain plug to a
torque of 90 Nm (65 lbf ft). Fill the engine with clean
lubricating oil specified in Section 300-0020,
LUBRICATION SYSTEM. The oil level should be
between the low (L) and high (H) marks on the
dipstick.
Note: Before starting the engine, follow the steps
below to make sure the engine receives correct
lubrication. Lack of lubrication will damage the engine.
a. Disconnect the electrical wire from the fuel pump
solenoid valve.
b. Switch on the ignition and rotate the crankshaft
using the starter motor, until oil pressure appears on
the pressure gauge or the warning light goes out.
c. Connect the electrical wire to the fuel pump solenoid
valve.
Start the engine and operate at idle speed to inspect
for leaks at the filter and oil drain plug. Shut off the
engine, wait approximately five minutes to let the oil
drain back to the sump and check the oil level again.
Add oil as necessary to bring the level to the high (H)
mark on the dipstick.
