Fluid Spillage Containment
Care must be taken to ensure that fluids are contained during
performance of inspection, maintenance, testing, adjusting and
repair of the machine. Be prepared to collect the fluid with
suitable containers before opening any compartment or
disassembling any component containing fluids. Refer to
"Tools And Shop Products Guide", NENG2500 for tools and
supplies suitable to collect and contain fluids in Caterpillar
machines. Dispose of fluids according to local regulations and
mandates.
At operating temperature, the engine coolant is hot and
under pressure. Steam can cause personal injury. Check
the coolant level only after the engine has been stopped
and the fill cap is cool enough to touch with your bare
hand. Remove the fill cap slowly to relieve pressure in the
cooling system. Cooling system conditioner contains
alkali. Avoid contact with skin and eyes to prevent
personal injury.
1.
Drain the coolant from the cooling system into a suitable
container for storage or disposal.
2.
Loosen bolts (1) and (2) on water pump drive (3).

pump and the pulley on the water pump drive.
4.
Remove two hose clamps (5). Disconnect the hose
used
between
the
water
pump
and
the
water

Remove four bolts (6) that hold the water pump to the
front of the engine. Carefully remove the water pump
and two O-ring seals from the front of the engine.
NOTE:
The following steps are for the installation of the
