Water Temperature Regulator - Replace; Water Pump - Inspect - Perkins 4016-61TRS1 Operation And Maintenance Manual

SEBU8430
•
Ensure that cooling lines are properly clamped.
Check for leaks. Check the condition of all pipes.
•
Inspect the water pumps for coolant leaks. Refer to
this manual, "Water Pump - Inspect".
Note: The water pump seal is lubricated by coolant
in the cooling system. It is normal for a small amount
of leakage to occur when the engine cools and the
parts contract.
•
Inspect the lubrication system for leaks at the front
crankshaft seal, the rear crankshaft seal, the oil
pan, the oil filters and the valve covers.
NEVER use a flame to check for gas leaks. Use a
gas detector.
An open flame can ignite mixtures of air and fuel.
This will cause explosion and/or fire which could
result in severe personal injury or death.
• Check the fuel system for leaks. Look for loose fuel
line clamps.
•
Inspect the piping for the air inlet system and the
elbows for cracks and for loose clamps.
• Inspect the wiring and the wiring harnesses for
loose connections and for worn wires or frayed
wires.
•
Inspect the ground straps for good connections
and for good condition.
• Check the condition of the gauges. Replace any
gauge that is damaged. Replace any gauge that
can not be calibrated.
•
Inspect the exhaust system for leaks. If a leak is
found, make repairs.

Water Pump - Inspect

A failed water pump might cause severe engine
overheating problems that could result in cracks in
the cylinder heads, a piston seizure or other potential
damage to the engine.
Refer to the latest issue of Perkins service bulletin
157 for more information on inspecting the water
pump.
