Pentosin Pentofrost NF Coolant Concentrate, 1.5L

Pentofrost NF Concentrate is an environmentally friendly Antifreeze concentrate for multipurpose applications in watercooled engines. It does not contain any nitrites, amines or phosphorous additives. Pentofrost NF protects all material used in cooling systems and is recommended for non-ferrous metals and year-round use. Meets ASTM D-3306, and is recommended for use in Volvos which used blue G48-spec coolant (all FWD/AWD Volvos up to 2014), and backwards compatible with RWD Volvos calling for conventional green silicate coolant.

Pentofrost NF Concentrate is bright blue, and is silicate based: it should not mixed with H-OAT or OAT coolants such as DEX-COOL, which are typically orange in color. We recommend a complete system flush whenever changing coolants, as even compatible older coolants will lose corrosion inhibition, pH balance, and microbial protection with age. Mix with 1.5 liters of distilled water before use.

This coolant matches the factory fill for all Volvos up until about 2014, with Volvo gradually introducing green G64 spec coolant with the new VEA 4-cylinders. If you've got one of these VEA-powered cars from 2014 onwards, we advise G64-compatible coolant only.

Additional Technical Information

This is a 1.5 liter bottle of coolant concentrate, and must be mixed with 1.5 liters of distilled water prior to use to achieve a 50/50 mix.

If flushing your current cooling system, keep overall system capacity in mind when adding concentrate. For example, if you flush with water until it runs clear, and your car has a 9.5 quart coolant capacity, ensure you add 4.75 quarts (4.5 liters) of concentrate with your final fill before topping off with water.

Product Fitment Notes & Potential Issues

For 4-cylinder VEA cars, green G64-spec coolant is recommended. Volvo began switching to this engine in 2014, though 5- and 6-cylinder engines stayed in some models until 2016.
