Working procedures
Check engine for air, fuel, oil and coolant leakage
Check for engine starting performance, idling speed,
abnormal engine noise, dark smoke or other abnormal
exhaust gas during idling and acceleration.
Check engine speed on tachometer
Check manifold bolts for looseness
Check valve clearance with feeler gauge
Replace element
Check injection nozzles
Remove injection nozzle and check with nozzle tester
Turn crankshaft in normal running direction and check
injection starting timing of No.1 cylinder
Remove connector from fuel feed pump inlet and clean
filter inside connector with gas oil
Replace element
Loosen water separator drain plug to discharge water
Remove fuel tank drain plug and remove water and
sediment
Check mounting bolts for looseness and retighten to a
torque of 34 to 54 N·m {25 to 40 lbf.ft, 3.5 to 5.5 kgf·m}
Replace fuel line in engine compartment
Check fuel line outside of engine compartment.
Replace if necessary
Press midpoint of V-belt firmly with your finger to
measure deflection and check for belt damage
Check coolant level and if level is low, check for coolant
leakage
Replace with new coolant
Check surge tank cap for sealing and mounting condition ^ Gr 14
Check clamp position and clamping condition of cooling
system hose
Check whether rotor has excessive end play using a
dial indicator
Check air cleaner dust indicator. If the red signal
appears, clean the element
Replace element
Check inlet system for damage and check that all parts
are installed
Check installation and connections for looseness and
damage, check for exhaust gas leakage
Operate starter switch and check the switch functions
properly
Check function with a circuit tester
