Changing engine coolant

Major cooling system repairs should be performed by an INFINITI retailer. The service procedures can be found in the appropriate INFINITI Service Manual. Improper servicing can result in reduced heater performance and engine overheating.
WARNING
► To avoid the danger of being scalded,
never change the coolant when the
engine is hot.
► Never remove the radiator cap or coolant
reservoir cap when the engine is hot.
Serious burns could be caused by high
pressure fluid escaping from the radiator.
► Avoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner as
soon as possible.
► Keep coolant out of reach of children and
pets.
Engine coolant must be disposed of properly. Check your local regulations.
