Filler cap
5.
Clean the cooling system filler cap and inspect the
gasket. If the gasket is damaged, discard the old
filler cap and install a new filler cap. If the gasket is
not damaged, use a suitable pressurizing pump in
order to pressure test the filler cap. The correct
pressure is stamped on the face of the filler cap. If
the filler cap does not retain the correct pressure,
install a new filler cap.
6.
Start the engine. Inspect the cooling system for
leaks and for correct operating temperature.

Check
Pressurized System: Hot coolant can cause seri-
ous burns. To open the cooling system filler cap,
stop the engine and wait until the cooling system
components are cool. Loosen the cooling system
pressure cap slowly in order to relieve the
pressure.
Note:
The Diesel Exhaust Fluid (DEF) tank requires
coolant flow around the tank. The Coolant Diverter
Valve (CDV) will turn the flow on or off. If the coolant
system has been filled with the CDV in the closed
position, coolant level will drop because of the
opening of the CDV.

NOTICE
When any servicing or repair of the engine cooling
system is performed, the procedure must be per-
formed with the engine on level ground. Level ground
will allow you to check accurately the coolant level.
This checking will also help in avoiding the risk of in-
troducing an air lock into the coolant system.
1.
Check the coolant level when the engine is
stopped and cool.
2.
Loosen filler cap slowly in order to relieve any
pressure. Remove the filler cap.
