No, you should not mix Dexcool with water. Dexcool is an extended-life antifreeze and coolant that is designed to be used as is, without dilution. Mixing it with water can dilute its protective properties and potentially lead to corrosion and other issues in the cooling system. Always refer to the manufacturer's guidelines for proper use and maintenance.
A 50/50 mix of distilled water and Dexcool antifreeze.
The factory recommends a 50/50 mix of clean water and Dexcool or similar (the "orange") stuff. This mix will protect the Northstar for up to 5 years. If you ever have used the "green" stuff (e.g. Non Dexcool) then you can go back to the Dexcool, but you'll have to change every two years or so.
DEXCOOL OR LONG LIFE,IF ITS NOT PREMIXED BE SUR TO MIX IT,60% COOLANT 40% WATER.
It uses "Dexcool" Antifreeze. This is the "red" stuff not the green. It is a different formula and cools better. NEVER mix the two together. If you have to flush your system, pour two gallons of "distilled" water after you finish flushing the radiator. This is to remove all the mineral laden water from your block. When you fill the radiator use a 50/50 mix of Dexcool and Distilled water. This will minimize the formation of mineral deposits.
GM has it for you. I believe they make it in Mexico, where your caddillac was made. hummer,etc. Gm has been in Mexico since 1935. So im sure they have plenty of dexcool handy.
The answer is no. any regular or universal antifreeze will gum up and ruin your entire cooling system when it is mixed with dexcool. If you want to use any green coolant you will need to drain and flush your your system first.
Dexcool, which is an extended-life coolant, should not be mixed with plain water. It is designed to be used with a specific 50/50 mixture of Dexcool and distilled water to ensure optimal performance and prevent corrosion. Mixing it with tap water or other coolants can lead to chemical reactions that may cause engine damage. Always follow the manufacturer's recommendations for coolant mixtures.
You could in an emergency, but do not mix Dexcool with any other types of coolant.
Generally, you should have about a 50/50 (%) mixed of antifreeze and distilled water. GM recommends using Dexcool antifreeze. I would recommend that you use whatever antifreeze that is in there now and stick with the 50/50 mix. Take Care, Greg Also take care that if your van came with Dexcool (red in color) DO NOT add normal anti-freeze (green) to it. The Dexcool is lifetime antifreeze, and it will GEL if you add normall to it and bye bye engine. If it's red top up with Dexcool, or flush and refill with normal. Regards Brash911
Dexcool mixed with 50% distilled water.
Because the manufacturer used a red dye instead of a yellow or green dye. Its called Dexcool and it is that cooler so can tell them apart dont mix them, and use dexcool as called for by GM. The coolant is red rather than green because it is not regular antifreeze. This is a special GM coolant known as DEXCOOL. Dexcool is a phosphate and silicate free coolant, coherently making it a more stable and longer lasting product.
All from 1995 to date require dexcool. There are several class action law suits against General Motors in reference to dexcool.
