Coolant Level - 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.
Check the coolant level when the engine is stopped
and cool.
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. This proce-
dure will allow you to check accurately the coolant
level. This procedure will also help in avoiding the risk
of introducing an air lock into the coolant system.
1.
Remove the cooling system filler cap slowly in
order to relieve pressure.
2.
Maintain the coolant level at the maximum mark
that is correct for your application. If the engine is
equipped with a sight glass, maintain the coolant
level to the correct level in the sight glass.
