Perkins 1206F-E70TA - Engine Aftertreatment; Water Pump - Inspect

• Inspect the rest of the fuel system for leaks. Look
for loose fuel line clamps.
• Drain the water and the sediment from the fuel
tank on a daily basis in order to ensure that only
clean fuel enters the fuel system.
• Inspect the wiring and the wiring harnesses for
loose connections and for worn wires or frayed
wires. Check for any loose tie-wraps or missing tie-
wraps.
• Inspect the ground strap for a good connection
and for good condition.
• Disconnect any battery chargers that are not
protected against the current drain of the starting
motor. Check the condition and the electrolyte
level of the batteries, unless the engine is
equipped with a maintenance free battery.
• Check the condition of the gauges. Replace any
gauges that are cracked. Replace any gauge that
cannot be calibrated.
Engine Aftertreatment
Check the condition of the coolant lines , Diesel
Exhaust Fluid (DEF) lines, and electrical connections.
Check that all clamps, clips, and tie-wraps are secure
and in good condition. Check that the DEF filler cap is
secure and that cap is clean and free from dirt.
Check the level of DEF in the tank is adequate for
operational purpose, if necessary fill the tank.

Water Pump - Inspect
A failed water pump may cause severe engine
overheating problems that could result in the following
conditions:
• Cracks in the cylinder head
• A piston seizure
• Other potential damage to the engine

(A) Weep hole
(B) Vent hole
Note: The water pump seals are lubricated by the
coolant in the cooling system. It is normal for a small
amount of leakage to occur. Refer to illustration 104
for the position of the weep hole and the vent hole.
Visually inspect the water pump for leaks.
Note: If engine coolant enters the engine lubricating
system the lubricating oil and the engine oil filter must
be replaced. This will remove any contamination that
is caused by the coolant and this will prevent any
irregular oil samples.
The water pump is not a serviceable item. In order to
install a new water pump, refer to the Disassembly
and Assembly Manual, “Water Pump - Remove and
Install”.
