Description

Genuine NAPA · Part no. N91420L

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

NAPA Ultra LL Yellow Antifreeze (N91420L) is an OAT coolant concentrate in a 20 litre drum for petrol and diesel engines in cars, commercial vehicles and some industrial uses. It has to be diluted before it goes in; at 50% dilution it freezes at -38.2°C, and its listed standards run from ASTM D 3306 to FFV HEFT R443 and NATO S 759.

Good to know

• Is yellow the right colour for my car? Colour is not a reliable guide. Check the coolant type and specification in the handbook; this is an OAT coolant, so use it where the handbook names an OAT type.
• How long does it last? NAPA's details are not consistent here, giving both 3-year and 5-year protection, so follow the coolant change interval in your car's own service schedule.
• How do I mix it? Equal parts concentrate and deionised or distilled water give the -38.2°C freeze point NAPA quotes at 50% dilution. Open the cap only with the engine cold.
• Can it go into a system holding another type? When changing a car from one coolant type to another, drain and flush the system first rather than mixing the two.

Which one?

Where the handbook asks for Glysantin G40 or GG40, NAPA Ultra LL Lilac 40 (N91220L) is listed for that; for phosphated OAT, NAPA Ultra LL P-Oat (N91520L).
