Clean the cooling system and flush the cooling
system before the recommended maintenance
interval if the following conditions exist:
• The engine overheats frequently.
• Foaming 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. Replace the water pump, the water
temperature regulator, and the hoses, if necessary.
NOTICE
Service or repair of the engine cooling system must
be performed on level ground. The engine must be
level to check the coolant level. The engine must be
level to avoid the risk of introducing 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.
