3.3.2 Changing Engine Oil

1) Operate the engine until it is warm.
2) Stop the engine. Remove the sump drain plug
and drain the lubricating oil from the sump.
Fit the drain plug and tighten the plug to 34
Nm (25lb-ft) (3.5 kgf-m).
3) Fill the sump to the 'FULL" mark on the
dipstick with new and clean lubricating oil of
an approved grade.
4) Dispose used oil properly.

3.3.3 Changing Oil Filter Cartridge

1) Put a tray under the filter to retain spilt
lubricating oil.
2) Remove the filter with a strap wrench or
similar tool.
properly.
3) Clean the filter head.
4) Add clean engine lubricating oil to the new
filter. Allow the oil enough time to pass
through the filter element.
5) Lubricate the top of the filter seal with clean
engine lubricating oil.
6) Fit the new filter and tighten it by hand only.
Do not use a strap wrench.
7) Ensure that there is lubricating oil in the sump.
On turbocharged engines, ensure that the
engine will not start and operate the starter
motor until oil pressure is obtained.
8) Operate the engine and check for leakage from
the filter. When the engine has cooled, check
the oil level on the dipstick and put more oil
into the sump, if necessary.
9) Return the unit back into service by returning
the main pump
"automatic" position and the manual operating
lever to AUTO-OFF position.
Then dispose of the filter

3.3.4 Oil Specification

Diesel Engine Oil
This engine is filled at Clarke with SAE 15W-40 oil
meeting CAT ECF-3 specification.
Important: Do not add makeup oil until the oil
level is BELOW the add mark on dipstick. Add Cat
DEO 15W-40 or equivalent when makeup oil is
required.

3.4 COOLING SYSTEM

3.4.1 Intended Engine Operating Temperature

The C18H engines are provided with either a heat
exchanger or radiator to maintain the engine coolant
temperature within recommended operating guidelines.
The C18H models have an intended engine operating
temperature of 190º F (88ºC) to 205º F (96º C). A high
coolant temperature
temperature and will set an alarm at 217º F (103º C).
3.4.2 Engine Coolant
The following information is provided as a guide for
Caterpillar Engine users in the selection of a suitable
coolant.
The water/ethylene glycol/inhibitor coolant mixture
used in Caterpillar engines must meet the following
basic requirements:

Provide for adequate heat transfer.

Provide protection from cavitation damage.

Provide a corrosion/erosion-resistant
environment within the cooling system.

Prevent formation of scale or sludge deposits
in the cooling system.

Be compatible with engine hose and seal
materials.

Provide adequate freeze and boil over
protection.
