ENGINE OIL CHANGING ENGINE COOLANT A NISSAN dealer can change the engine coolant. The service procedure can be found in the 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, wash thoroughly with soap or hand cleaner as soon as possible. ● Keep coolant out of the reach of children and pets. Engine coolant must be disposed of properly.
