Leakage check

See Fig. 8.
Visual inspection of the whole engine for leakage:
◆ NOTE:
The engine must be run until the temperatures have stabilized for a period of
5 minutes. Then shut down the engine and turn the ignition to "OFF" to ensure
that it cannot be turned on unintentionally. No liquid should drip out for 1 min.
after shutting down the engine.
There is a leakage bore on the bottom side of the water pump. If this opening
is dripping oil, the oil seal on the water pump shaft is faulty and must be replaced.
If there is a coolant leak, the coolant rotary seal must be replaced.
Inspect all fuel lines and their connections and fasteners. Look for scuffing
marks.
Inspect all oil feed lines from the oil tank to the oil cooler and to the engine. Also
inspect the oil return line from the crankcase to the oil tank. Check the pressure
oil line from the oil pump to the governor flange of the governor and the suction
oil line from the turbocharger to the oil pump.
Check coolant hoses and connections and fittings for leakage. Examine the
surrounding area to see if there are any leaks!
If leaks are visible, locate the cause and remedy the fault.
Check all hoses, particularly in the area of the hose clamps and hose
connections, for porosity, damage and kinks. If damage is detected, replace
hose immediately.
