5. Cut cable tie (3).
6. Loosen hose clamp (4) and remove hose (5).
7. Remove nut (1) and washer (2).
Always use a mixture of antifreeze and fresh
water in the engine cooling system. Normally a
50/50 coolant mixture will provide freeze
protection to -37°F (-38°C) and boil-over
protection in an efficient cooling system.
Allow the engine coolant to completely cool
before removing the radiator cap. Hot coolant
sprayed from the cap can cause serious personal
injury.
Never remove the radiator cap when the coolant
is hot. The engine must be shut down and cooled
before the radiator cap is removed. Very hot
coolant will be sprayed from the radiator if the
cap is loosened before the engine has cooled.
Serious personal injury can occur.
