What happens if you use the wrong color 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.

Can I use any color of coolant?

Green or orange should work

in the cooling system of just about any vehicle on the market, so you don’t need to worry about whether or not you have a brand that was specifically made for your car. The problem with green and orange antifreeze is that they do not work together.

. There may be a floating sensor in your coolant tank that triggers the warning light when the level drops. … Low coolant levels are usually caused by leaks, either in the reservoir or somewhere in the lines.

Can I use green coolant instead of orange?

Can I Mix Different Engine Coolant Types? The short answer –

no

. When orange and green antifreeze mix, there’s likely to be a chemical reaction that causes it to thicken into a gel-like substance. Since your engine needs fluid rather than gel, it’s unable to effectively cycle it through the system.

What are the signs of low coolant?

Warning signs of low or no coolant/antifreeze:

Rising temperature gauge

: A rising temperature gauge may be due to an increase in your engine’s temperature. Automatic engine cut-off: Most modern cars are equipped with an automatic engine cut-off feature. When coolant is low, your engine will start to heat up.

How do you know when your coolant is full?

Do coolant additives really work?

But over the years we’ve become accustomed to using cooling system wetting agents, as they’ve been proven to work almost every time. Unlike ring sealers in a can and other mysterious leak sealing products that never seem to work,

cooling system additives generally do work.

Can I mix pink and green coolant?

You can mix two different colors of the same kind of coolant without any problem whatsoever

. But if you mix a significant amount of one type in with the other type, you’re weakening your corrosion inhibitors (it happened to my brother, and look at the condition he’s in now).

Can I mix different brands of coolant?

If you mix two different coolants together, it

will create a think substance
