Engine Coolant
DANGER
SCALD HAZARD!
NEVER remove the radiator cap if the engine is
hot. Steam and hot engine coolant will spurt out
and seriously burn you. Allow the engine to cool
down before you attempt to remove the radiator
cap.
Tighten the radiator cap securely after you
check the radiator. Steam can spurt out during
engine operation if the cap is loose.
ALWAYS check the level of the engine coolant
by observing the reserve tank.
Failure to comply will result in death or serious
injury.
WARNING
BURN HAZARD!
Wait until the engine cools before you drain
the engine coolant. Hot engine coolant may
splash and burn you.
Failure to comply could result in death or
serious injury.
CAUTION
COOLANT HAZARD!
Wear eye protection and rubber gloves when
you handle long life or extended life engine
coolant. If contact with the eyes or skin should
occur, flush eyes and wash immediately with
clean water.
Failure to comply may result in minor or
moderate injury.
CAUTION
Only use the engine coolant specified. Other
engine coolants may affect warranty coverage,
cause an internal buildup of rust and scale and /
or shorten engine life.
Prevent dirt and debris from contaminating the
engine coolant. Carefully clean the radiator cap
and the surrounding area before you remove the
cap.
NEVER mix different types of engine coolants.
This may adversely affect the properties of the
engine coolant.
