CHANGING ENGINE COOLANT

￿Major cooling system repairs should be per- formed by a 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 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, wash thoroughly with soap or hand cleaner as soon as possible.

￿Keep coolant out of reach of children and pets.

1.Open radiator drain plug at the bottom of radiator, and remove radiator filler cap.

￿Be careful not to allow coolant to con- tact drive belts.

￿Waste coolant must be disposed of properly. Check your local regulations.

2.Close the radiator drain plug securely after the coolant is drained.

3.Fill the radiator slowly with the proper mixture of anti-freeze solution and demineralized water/distilled water. Fill the reservoir tank up to the MAX level. Then install the radiator filler cap.

4.Start the engine and warm it up until it reaches normal operating temperature. Then race the engine 2 or 3 times under no load. Watch the engine coolant temperature gauge for signs of overheating.

5.Stop the engine. After it completely cools down, refill the radiator up to the filler open- ing. Fill the reservoir tank up to the MAX level. Check the drain plug for any sign of leakage.

6.Recheck the coolant level after the vehicle has been driven for a day.
