If this happens, the coolant will not be able to do its intended job. If you mix two different coolants together, it will create a think substance that resembles that of a jelly. PEAK® Antifreeze + Coolant is a conventional (green), ethylene glycol based antifreeze for use in older automotive and light duty diesel applications. Whatever you do, don’t mix green/blue with orange. You can, but if it was me, I’d rather fill the system with distilled water until I got the proper coolant for the car. We recommend the traditional yellow/green coolant because it has always worked for us. While the manufacturers of these coolants recommend only using them in an aluminum radiator, as opposed to the copper/brass radiators, we still don’t recommend them in our all-aluminum radiators. Using the wrong engine coolant can gradually lead to corrosion and damage to the water pump, radiator, radiator hoses and cylinder gasket. Mixing different engine coolants or using the wrong coolant can impair the performance of the special additive packages this can result in increased corrosion to the radiator. What happens if you put the wrong color coolant in your car? HOAT uses both silicates and organic acid to protect your engine and combat corrosion. The HOAT formulation is a combination of the OAT formulation and the IAT formulation. To make sure you’re choosing the right HOAT coolant, look at the brand name, rather than the liquid’s color. A rusty color indicates that the rust inhibitor in the coolant has broken down and it can no longer control rust and scale buildup.

The color of healthy engine coolant is green (for ethylene glycol) or orange (for Dexcool). For example, OAT coolants are usually orange, yellow, red or purple. Does it matter what color the coolant is?īut what about different colored coolants? The truth is, color is not a reliable predictor for what type of coolant you have. “Older coolants that used Inorganic Additive Technology (IAT) were usually blue or green in colour. “In days gone by, the colour of coolant was determined by the type of chemicals used to prevent corrosion - meaning you could tell a lot about the type of coolant used by its colour. Alliance Green CoolantĪlliance Green Coolant is a Conventional low silicate Automotive formula that requires the addition of Supplemental Coolant Additives to be used in Heavy Duty Diesel applications.2 What do the different colors of coolant mean? Alliance Fully Formulated SCA Pre-Charged CoolantĪlliance Fully Formulated SCA Pre-Charged Heavy Duty Diesel Engine Coolant is pre-charged with supplemental coolant additives in a Pink Conventional low silicate, non-phosphate formula that helps prevent inhibitor dropout, scale deposits, and gel problems frequently associated with diesel engine cooling systems for 2 years/25,000 miles.

Alliance OAT Extended Life Coolant keeps the cooling system running cooler and components lasting longer while providing complete protection against corrosion, erosion and cavitation for 1,000,000 miles/20,000 hours of cooling system protection. Alliance OAT Extended Life CoolantĪlliance OAT Extended Life Coolant is a NITRITE-FREE, patented, non-silicate, non-phosphate formula that eliminates inhibitor dropout and scale problems. Our coolants provide reliable protection in even the most extreme heat and freezing cold conditions. Alliance Extended Life coolants are different – specifically formulated to not just meet, but to exceed the performance requirements of your
