Heat transfer is the most important coolant property. Extended life coolants with OATs offer improved heat transfer over conventional coolants.
Today’s modern engines demand effective heat transfer, freeze and boiling protection and corrosion protection for the cooling system. Our wide variety of coolant products satisfy these requirements and help reduce overall maintenance costs.
Did you know that more than 20% of engine failures are associated with cooling system failures? Coolants are designed to protect engines from overheating and protect the cooling system from damage caused by corrosion, scaling and sediment build-up.
However, the use of poor-quality coolants can cause heat transfer problems and corrosion, which may result in expensive breakdowns and parts failures. High-quality coolants prevent this damage, keeping your vehicle on the road and out of the workshop.
