Infiniti QX: Checking engine coolant level

Check the coolant level in the reservoir

Check the coolant level in the reservoir when the engine is cold. If the coolant level is below MIN 2 , open the reservoir tank cap and add coolant up to the MAX1 level. If the reservoir tank 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 tank up to the MAX level 1 . Tighten the cap securely after adding engine coolant. 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 INFINITI Service and Maintenance Guide for more details. If the cooling system requires coolant frequently, have it checked by an INFINITI retailer.
