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.

NOTICE
Care must be taken to ensure that fluids are con-
tained during performance of inspection, mainte-
nance, testing, adjusting and repair of the product.
Be prepared to collect the fluid with suitable contain-
ers before opening any compartment or disassem-
bling any component containing fluids.
Dispose of all fluids according to Local regulations
and mandates.
NOTICE
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened
component life.
Clean the cooling system and flush the cooling
system before the recommended maintenance
interval if the following conditions exist:
• The engine overheats frequently.
• Foaming of the coolant is observed.
• The oil has entered the cooling system and the
coolant is contaminated.
• The fuel has entered the cooling system and the
coolant is contaminated.
Note: When the cooling system is cleaned, only
clean water is needed when the ELC is drained and
replaced.
Note: Inspect the water pump and the water
temperature regulator after the cooling system has
been drained. This inspection can be a good
opportunity to replace the water pump, the water
temperature regulator, and the hoses, if necessary.

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 check will also help in avoiding the risk of intro-
ducing an air lock into the coolant system.
Drain
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.
1. Stop the engine and allow the engine to cool.
Loosen the cooling system filler cap slowly in
order to relieve any pressure. Remove the cooling
system filler cap.
