Smith & Allan Cooltech 41 HD - Yellow Antifreeze OAT

Description
Cooltech 41 HD is a high-quality antifreeze coolant which is primarily intended for use in heavy duty, commercial, off-highway and agricultural applications, but is suitable for many liquid cooled petrol or diesel engines, offering a long-life and cost effective coolant solution for mixed fleet operations.
This ethylene glycol-based coolant contains an Organic Acid Technology (OAT) inhibitor package and is Nitrate, Amine, Phosphate, borate free. The product provides all year-round frost and corrosion protection and is particularly suited to engines equipped with cooled exhaust gas recirculation (EGR) and eliminates the risk of deposits particularly near the cylinder head, engine block, radiator, water-pump and heat exchanger.
The product safely protects wet cylinder liners and sleeves from cavitation and pitting, avoiding costly downtime and repairs, exceptional thermal oxidative stability can be expected, with either zero or minimal material mass losses to copper, solder, brass, steel, cast iron and aluminium components operating under aggressive thermal conditions. The product may be used neat as supplied for extreme use or diluted for economic use.

Protection Levels
Extreme (Use Neat) -37°C
Normal (CT 41 HD 66% / Water 33%) -19°C
**Use neat for wet cylinder liner & sleeve protection**
