Is universal antifreeze safe?

Which type of coolant should you use to top off or refill your cooling system? Even so, universal coolants are formulated to mix with virtually any coolant. The makers of these product say their antifreeze can be safely used in any year, make or model of vehicle.

Is Dex Cool antifreeze a problem?

In the 1990s, GM introduced an engine coolant called Dexcool. It’s supposed to last 5 years or 150,000 miles, but there have been problems with this coolant. Cooling systems that use Dexcool exhibit more acid buildup and rust in the system when the coolant level gets low and oxygen is allowed to enter the system.

Is it okay to mix red and green antifreeze?

It’s perfectly backwards compatible if you want to do that. But you really don’t want to mix them, it’s not that good of an idea to mix them. If you want to have the correct coolant added for you, consider YourMechanic. They will be able to come to your home or office to perform this service.

Is it OK to mix green and yellow antifreeze?

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).

Is there a 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.

Can I mix old antifreeze with new?

Yes, certainly you can. Use the same color antifreeze that’s in there now. Modern automotive cooling systems should not need flushed or drained, so long as they are filled with only quality modern antifreeze and distilled water.

What happens if you use universal coolant?

When a universal coolant is used to top off a cooling system that already contains an extended life OAT or hybrid coolant, the service life is unaffected. It remains five years or 150,000 miles. The corrosion inhibitors in all types of coolant eventually wear out and must be replenished by changing the coolant.

What happens if I mix green and orange coolant?

Some people believe that they can mix the two. This is a mistake and can lead to expensive repairs. The two coolants should never be mixed together as they do not react well. When mixed together they can form a thick, jelly-like substance that can completely stop all coolant flow which can lead to overheating.

Is Dex cool better than antifreeze?

For a couple decades now, GM has used a type of coolant known as Dex-Cool. Despite not being called antifreeze, it still accomplishes the same task, so you don’t have to worry about replacing Dex-Cool for the winter months or anything like that.
