What kind of coolant is orange coolant?

One of the new types is “organic acid technology,” or OAT. It’s orange. General Motors pioneered this chemistry starting with 1996 models in the U.S. and using the name Dex-Cool. Ford changed a few models to OAT, then backed away from it.

Do diesel engines need special coolant?

Engine coolant maintenance is just as important as an oil change. In fact, the coolant condition in a diesel engine may even be more important than in a gasoline engine. Today’s antifreeze-coolant not only protects from freezing in the winter months, but also helps protect diesel engines from common cavitation issues.

Is it bad if my coolant is orange?

Watch for signs of oil or rust. The color of healthy engine coolant is green (for ethylene glycol) or orange (for Dexcool). A rusty color indicates that the rust inhibitor in the coolant has broken down and it can no longer control rust and scale buildup.

What color is diesel engine coolant?

OAT coolants are designed for use in heavy and light-duty diesel engines, as well as natural gas and gasoline engines. Color: orange or red, but can also come in yellow, blue, red and dark green depending on the manufacturer.

Are all orange coolant the same?

What color is Dex-Cool®?” It’s true, coolant liquid comes in different colors, most commonly green (orange for Dex-Cool®). Each color is a unique formula that should not be mixed. Reminder, you can often find the recommended type of coolant in your vehicle’s owner’s manual.

Does the color of coolant matter?

The truth is, color is not a reliable predictor for what type of coolant you have. For example, OAT coolants are usually orange, yellow, red or purple. Then the older IAT coolant is green. Coolants that manufacturers sell can confuse matters even more, like Honda’s blue coolant.

Is antifreeze different for diesels?

The difference between the antifreeze used in a diesel engine and that used in a conventional gas engine is that diesel antifreeze contains a special additive that protects against erosion on cylinder walls.

What kind of coolant do you use with a diesel?

For diesel trucks using green antifreeze, the recommendation of coolant service is usually around two years or 30,000 miles. For diesel engines running extended-life coolant, service is around five years or 100,000 miles. To be on the safe side, periodically check the antifreeze every six months.

When should you change orange coolant?

Coolant manufacturers updated the formula to combat corrosion in new materials and changed the color to orange. While OAT antifreeze is designed to last much longer than IAT antifreeze, it’s still a good idea to have your orange coolant checked about every 50,000 miles.

What’s the difference between Green and orange coolant?

The color of healthy engine coolant is green (for ethylene glycol) or orange (for Dexcool). A rusty color indicates that the rust inhibitor in the coolant has broken down and it can no longer…

What’s the best color for a diesel coolant?

The color of ELC is usually bright red or pink. Typical ELC can go for up to a five-year interval before changing is recommended. ELCs (Nitrited Extended Life Coolant) Organic Acid technology for aluminum and iron protection

What kind of coolant does a Ford engine need?

Protect your engine with Motorcraft VC-3-B Orange Concentrated Antifreeze/Coolant. Recommended by Ford Motor Company, this coolant has been designed for use in vehicles requiring antifreeze/coolant meeting Ford Specification WSS-M97B44-D. This concentrated orange coolant provides year-round antifreeze, anti-boil and corrosion protection.

What is the color of XLC diesel coolant?

The color of XLC is typically orange in the heavy-duty market, but may be offered in other colors. Beware of how coolant has changed over the past 10 years. Remember, antifreeze when manufactured is a clear liquid. Different dyes are added to the antifreeze to indicate what type of coolant it represents.
