Nissan coolant: what coolant does Nissan use?

Confirm the code in your owner’s manual before buying.

What coolant does Nissan use?

• Nissan's official US parts store lists Nissan Long Life Coolant (Blue), part number 999MP-L25500P, also called "Engine Coolant / Antifreeze". [1]
• The parts page does not publish chemistry, premix ratio or a spec code. Coolant makers that target Nissan cite "Nissan L25500P" or simply name Nissan/Infiniti. [1]

How Nissan coolant changed over the years

Nissan and Infiniti specify a blue factory coolant, sold as Nissan Long Life Antifreeze/Coolant (Blue) [2]. Nissan's 2016 maintenance guide sets a long first interval and a shorter repeat interval [2].

Nissan coolant chemistry

Neither the parts page nor the maintenance guide gives a chemistry family for Nissan blue coolant [1]. Treat any claim about its chemistry as a third-party claim.

Known Nissan coolant issues

• Nissan says it "does not advocate the use of non-OEM approved aftermarket flushing systems" and strongly advises against them on a Nissan [2]. A drain and refill with Nissan blue is the conservative choice.
• The guide says to use only Genuine Nissan Long Life Antifreeze/Coolant (Blue) "or equivalent with the proper mixture" [2].
