2003 NISSAN PATHFINDER heater

CHANGING ENGINE COOLANT
Major cooling system repairs should be per-
formed by your NISSAN dealer. The service
procedures can be found in the appropriate
NISSAN 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 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, washthoroughly with soap or hand cleaner
as soon as possible.

Keep coolant out of reach of children
and pets.
