If you do mix different-coloured coolants they generally do not mix well and some can form a gel-like substance. This will halt coolant flow, causing blockages that can lead the engine to overheat, as well as damage to the radiator, water jackets and heater core. Also, the water pump can overheat and fail.
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.
Beside this, What does the color of antifreeze mean?
“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. “Older coolants that used Inorganic Additive Technology (IAT) were usually blue or green in colour.
Likewise, Can I use a different color antifreeze?
The problem with green and orange antifreeze is that they do not work together. They were designed to function in different ways. Orange antifreeze is a long-life antifreeze. It has a different chemical makeup than green, and they cannot be used interchangeably unless you have flushed your cooling system ahead of time.

What happens if you use the wrong antifreeze?
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. … Using the wrong engine coolant can gradually lead to corrosion and damage to the water pump, radiator, radiator hoses and cylinder gasket.
