Does Dex-cool need to be diluted?
In extremely cold environments, the ratio for standard ethylene glycol can go as high as 70% antifreeze, 30% water. With DEX-COOL®, the maximum ratio of antifreeze to water is 60/40. All coolants must be diluted with water at the proper ratios and should not be used full-strength.
Can you use straight Dexcool?
Dex-cool is fine. As said, it’s pretty pointless to use anymore than a 50/50 mix. Personally, I used to run something like a 25/75 mix of dexcool and water.
Can you use regular antifreeze instead of Dex-cool?
So if you don’t want to use dex-cool, the system needs to be drained and thoroughly flushed. Then it should be ok to use regular anti freeze. VW however warns against using anything other than their coolant, saying it can erode gaskets etc. So ultimately stick with what your recommended fluids.
Can you add water to orange coolant?
They are traditionally green or orange. Antifreeze is a pure substance that does need to be mixed with equal parts water to make an acceptable engine coolant.
Can I mix Prestone with Dex-cool?

Can you mix universal coolant with DexCool?

When did GM stop using Dex-cool?
Dex-Cool, which is made by Texaco, is being used exclusively by General Motors in some buildout 1995 models and all 1996 cars and trucks except Saturn and Geo.

What happens if I put too much water in my coolant?
Coolant expands as it heats and contracts when it cools. The extra space prevents damage to your engine and hoses. In worst case scenarios, overfilling your antifreeze tank can lead to electrical damage if overflow comes into contact with engine wiring.
What happens if coolant to water ratio is too high?
Having too much water will not cool the engine as well as a 50-50 mix, and having too much antifreeze could cause your water pump to fail. Since antifreeze is much thicker than water, your water pump has to work twice as hard to pump pure antifreeze than it does a 50-50 mix.
Can you mix dexdex-cool with regular coolant?
Dex-Cool is a specially formulated GM coolant which will not mix with traditional coolants, and was used in various GM applications up through the 2004 model year. Mixture of alternate chemicals will void the GM endorsement, will degrade coolant integrity, and possibly damage the coolant system…
What is DEX COOL made of?
PRODUCT DETAILS. GM OE Dex-Cool Antifreeze Extended Life Coolant Concentrate is an orange, silicate and phosphate free, premium-grade coolant/antifreeze that is formulated with a chemical composition that minimizes breakdown of metal components in contact with the fluid.
