Can you use water instead of Dex-cool?
For a very short time you can use clean water, the boiling point is lower than a 50/50 coolant mix so you need to replace it with coolant as soon as possible. There are no corrosion additives so if you do not replace the water the system will be damaged in a short time.
Does antifreeze run cooler than water?
Yes, water cools (transfers heat) better than coolant, but as others have pointed out, this has some potential downsides depending on how you use the car. Subsequently, question is, can water be used instead of coolant? Yes, the water can be used as a coolant only in unavoided situations.
What cools faster water or antifreeze?
A coolant liquid abrorbs higher amount of heat than plain water. It also cools down faster. When it passes through the engine column it absorbs the engine heat (energy) and than radiates to the surroundings in the radiator. Hence a coolant can lower the engine temperature more than water.
Are there any problems with GM’s Dexcool coolant?
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.
How long does GM DEX COOL antifreeze last?
On its website, GM claims Dex-Cool will last 5 years or 150,000 miles but a steady stream of consumers insist the product is defective and has damaged their vehicles. GM is quick to clarify its confidence in the antifreeze by stating that the GM owner’s manual recommended 150,000-mile service interval is…
Can you mix Dexcool with regular antifreeze?
On GM’s own consumer site, the debate regarding its Dexcool antifreeze continues. And in mixing any antifreeze with water for a 50/50 mix, the use of distilled water is highly recommended. I mix it with distilled water and some water wetter from Redline.
Do you have to use DEX COOL on your car?
If your car or truck came from the factory with Dex-Cool, you should continue to use that coolant both as replacement and to top off the radiator, the mechanics say. Last but not least, if your car came from the factory with standard “green” antifreeze, don’t switch to Dex-Cool.

Where is the low coolant message on a Duramax?
During PDI, coolant should be added to fill the upper chamber of the radiator surge tank. (Fig. 6) A coolant level that is low enough to turn on the Low Coolant message will be below the horizontal line across the radiator surge tank. (Fig.
Do you have to flush your Radiator with Dexcool?
This way you don’t introduce any contaminants. But it won’t hurt to use a universal long life coolant either, just drain the radiator and block, then refill, no flush. A little residual dexcool won’t hurt anything near as much as contaminants from flushing would.
Can you use long life coolant without Dexcool?
But it won’t hurt to use a universal long life coolant either, just drain the radiator and block, then refill, no flush. A little residual dexcool won’t hurt anything near as much as contaminants from flushing would. I kept the Dex too but had the shop change it for me.
