Description

Genuine NAPA · Part no. N91520L

Safety: Warning. Harmful if swallowed. May cause damage to organs through prolonged or repeated exposure. Read the label before use.

NAPA Ultra LL P-Oat (N91520L) is a phosphated OAT coolant concentrate for modern vehicles from Asian makers that call for that chemistry. The 20 litre drum is mixed with water before use; at 50% dilution it freezes at -37.7°C, and NAPA rates it for 5 years of protection.

Good to know

• Which cars need phosphated OAT? Mostly modern cars from Asian makers, but the handbook is the authority: use this only where it names a phosphated OAT coolant.
• What water should I use? Deionised or distilled water, mixed in equal parts with the concentrate, gives the -37.7°C figure NAPA quotes; hard tap water can leave scale in the radiator and passages.
• Is it a top-up coolant? It is meant for a drain and refill to the maker's specification. For a quick top-up of a mixed or unknown system, a ready-mixed universal coolant is the simpler choice.
• How do I check the strength afterwards? A coolant tester or refractometer shows the freezing protection of the mix in the car, which confirms the dilution came out right.

Which one?

Exopro Ultra LL P-OAT (U915D20L) is the same phosphated OAT type; where the maker asks for a silicated-phosphated coolant, choose NAPA Ultra LL Sp-Oat 64 (N91620L).
