Nissan Frontier: Do-it-yourself - Engine cooling system
Basic information Nissan Frontier 2022
The Nissan Frontier engine cooling system is filled at the factory with a pre-diluted mixture of 50% Genuine NISSAN Long Life Antifreeze/Coolant (blue) and 50% water. This mixture is designed to provide year-round coolant performance, freeze protection, and reliable engine temperature control.
The antifreeze solution also contains rust and corrosion inhibitors that help protect the radiator, engine passages, hoses, and other cooling system components. Additional cooling system additives are not required and should not be used unless specifically recommended.
WARNING
- Never remove the radiator cap or coolant reservoir cap while the Nissan Frontier engine is hot.
Allow the engine and radiator to cool completely before opening the system. Hot coolant under pressure can escape suddenly and cause serious burns.
- The radiator and coolant reservoir are equipped with a pressure-type radiator cap. To help prevent engine damage and maintain proper cooling system pressure, use only a Genuine NISSAN radiator cap.
CAUTION
- Never use cooling system additives such as radiator sealers. These products may clog passages inside the cooling system and can damage the Nissan Frontier engine, transmission, radiator, heater core, or related components.
- When adding or replacing coolant, use only Genuine NISSAN Long Life Antifreeze/Coolant (blue) or an
equivalent coolant. Genuine NISSAN Long Life Antifreeze/Coolant (blue) is pre-diluted to provide
antifreeze protection down to -34ºF (-37ºC). If additional freeze protection is required because of
the climate where the Nissan Frontier is operated, add Genuine NISSAN Long Life Antifreeze/Coolant
(blue) concentrate according to the directions on the container. If an equivalent coolant other than
Genuine NISSAN Long Life Antifreeze/Coolant (blue) is used, follow the coolant manufacturer’s
instructions to maintain minimum antifreeze protection down to -34ºF (-37ºC).
Using coolant other than Genuine NISSAN Long Life Antifreeze/Coolant (blue) or a proper equivalent may damage the engine cooling system.
- The expected service life of the factory-fill coolant is 105,000 miles (168,000 km) or 7 years. Mixing any other coolant type with Genuine NISSAN Long Life Antifreeze/Coolant (blue), including Genuine NISSAN Long Life Antifreeze/Coolant (green), or using non-distilled water may shorten the service life of the factory-fill coolant. For additional details, refer to the "Maintenance and schedules" section of this manual.
Checking engine coolant level Nissan Frontier 2022
Check the coolant level in the reservoir only when the Nissan Frontier engine is cold. If the coolant level is below the MIN mark B, add coolant until it reaches the MAX mark A. If the reservoir is empty, check the coolant level in the radiator after the engine has cooled completely. If the radiator level is low, fill the radiator with coolant up to the filler opening, then add coolant to the reservoir until it reaches the MAX level A.
This vehicle contains Genuine NISSAN Long Life Antifreeze/Coolant (blue). The factory-fill coolant is designed to last up to 105,000 miles (168,000 km) or 7 years under normal conditions. Mixing other coolant types or using non-distilled water will reduce the expected life of the factory-fill coolant. For more information, see the "Maintenance and schedules" section of this manual.
If the cooling system frequently requires additional coolant, there may be a leak or another system concern. It is recommended that you visit a NISSAN dealer for inspection and service.
Changing engine coolant
A NISSAN dealer can replace the Nissan Frontier engine coolant using the correct service procedure. The proper procedure is described in the NISSAN Service Manual.
Improper coolant replacement or incorrect servicing can reduce heater performance and may cause engine overheating.
WARNING
- To avoid the risk of scalding, never change the coolant while the engine is hot.
- Never remove the radiator cap or engine coolant reservoir cap while the Nissan Frontier engine is hot. Pressurized hot coolant can escape from the radiator and cause serious burns.
- Avoid direct skin contact with used coolant. If coolant contacts your skin, wash the affected area thoroughly with soap or hand cleaner as soon as possible.
- Keep engine coolant out of the reach of children and pets. Coolant is hazardous and must be handled carefully.
Engine coolant must be disposed of properly and never poured onto the ground, into drains, or into household waste systems.
Check and follow all local regulations for coolant disposal. Proper coolant maintenance helps protect the Nissan Frontier engine from overheating, freezing, corrosion, and long-term cooling system damage.
