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. LDI0436 LDI0466 VQ40DE CHECKING ENGINE COOLANT LEVEL Check the coolant level in the reservoir when the engine is cold. If the coolant level is below the MIN level, add coolant to the MAX level. If the reservoir is empty, check the coolant level in the radiator when the engine is cold. If there is insufficient coolant in the radiator, fill the radiator with coolant up to the filler opening and also add it to the reservoir up to the MAX level. QR25DE This vehicle contains Genuine NISSAN Long Life Antifreeze/Coolant (blue). The life expectancy of the factory-fill coolant is 105,000 miles (168,000 km) or 7 years. Mixing any other type of coolant or the use of non-distilled water will reduce the life expectancy of the factory-fill coolant. Refer to the NISSAN Service and Maintenance Guide for more details. The engine coolant reservoir is a pressurized tank. When installing the cap, tighten. If the cooling system frequently requires coolant, have it checked by a NISSAN dealer. ● Never remove the radiator or engine 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 the reach of children and pets. Engine coolant must be disposed of properly. Check your local regulations. Maintenance and do-it-yourself 8-9
