HD OAT NF Extended Life Antifreeze/Coolant

Turbo Power HD OAT NF Extended Life Antifreeze/Coolant is based on a proprietary organic acid corrosion inhibitor package powered by RECO-COOLTM technology (OAT).

This ethylene glycol based product is free of amines, borates, nitrites and silicates. Its’ proprietary OAT corrosion inhibitors DO NOT contain any 2-EHA. It protects the latest coolant system materials against corrosion and deterioration and provides excellent high temperature aluminum and wet sleeve liner cavitation protection. This product is designed for intense heavy duty diesel applications where high heat and aluminum protection is required. It is recommended for use in all on-road and off-road vehicles including, but not limited to, Caterpillar, Cummins, Detroit Diesel/MTU, GM Heavy Truck, Freightliner, PACCAR/DAF and Volvo Mack.

*When added as an initial fill and properly maintained in accordance with engine manufacturer’s maintenance recommendation, this product will provide an in-service life of up to 1,600,000 kilometres, 20,000 hours or 8 years, whichever comes first. While deleterious effects are not expected to be significant, mixing with conventional coolants will result in a lower than expected lifetime.

Never use 100% coolant in concentrated form. A 50% dilution (i.e. when mixed with an equal volume of high quality soft, de-ionized or distilled water) is generally recommended for the best balance of protection against freezing, corrosion and summer boil-over. For increased freeze protection in extremely cold areas, a 60% volume concentration can be used. Concentrations of greater than 70% by volume are not recommended.

HD OAT NF Extended Life Antifreeze/Coolant has been formulated to meet and is recommended for use with the following industry and OEM coolant specifications:  ASTM D3306, D4985, D6210, D7583; AS/NZS 2108.1:1997 “Type A”; BS 6580, BS5117; Caterpillar EC-1; CID-A-A-52624; Cummins 3666132 & 14603; Detroit Diesel 7SE 298 & 93K217; Freightliner 48-22880; GM 1825M, 1899M and Heavy Truck; Navistar/ ITE CEMS B-1 Type III-A; JIS K2234; Kenworth R026-170-97; MACK 014GS17004 & 014GS17009; MAN 324; MTU MTL 5048; PACCAR CS0185; Peterbilt 8502.002; TMC RP 338, TMC RP 329B; Volvo
