Engine Valve Lash
(Diesel E/G Only) - Check, Adjust
NOTICE
The valve clearances are to be adjusted at the times
of the following situations.
 When the engine is overhauled and the cylinder
heads are disassembled.
 When severe noise comes from valve train.
 When the engine is not normally operated even
though there is no trouble in the fuel system.
WARNING
To prevent possible injury when adjusting diesel
engines, do not use the starter motor to turn the
flywheel.
Hot engine components can cause burns. Allow
additional time for the engine to cool before
measuring valve clearance.
NOTICE
Measure the valve lash with the engine stopped. To
obtain an accurate measurement, allow at least 20
minutes for the engine cylinder head and block to
cool.
Set the clearance to the nominal appropriate

Inspecting Engine Fuel Supply
System
WARNING
Once a lot of foreign substances or water are
detected in the fuel supply line, the warning
function is activated. Failure to check the fuel
supply line in response to the warning may
cause a serious fault or damage in the engine.
Separating Water from Fuel
Once water is detected in the fuel, the water-in-fuel
warning function is triggered to set off the warning
buzzer, light up the warning lamp, and derate the
engine. If a water-in-fuel warning occurs, check the
fuel supply line as follows:
1. Turn off the engine and put a drip pan on the
floor to catch drained fuel.
2. Remove the plug at the bottom of the fuel filter
and wait until all fuel and water drain out of the
filter.
3. Once they drain out, mount the plug and
remove air according to the fuel system priming
procedure.
4. Start up the engine and check if the warning
has been cleared and the vehicle operates
normally.
