When mixed together they form a gel-like substance that stops coolant flow and consequently the engine overheats.

The green and orange coolants do not mix. Mixing universal with Dexcool antifreeze will almost guarantee the mixture will gel and sludge in your cooling system. 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).Ĭan you add universal antifreeze to Dexcool?

When mixed together they form a gel-like substance that stops coolant flow, and consequently, the engine overheats. What happens if you mix Dexcool with regular antifreeze? 8 Do you still use Dexcool in your Saturn?.6 Is Peak antifreeze the same as Dexcool?.

If you use the wrong coolant it does not have the lubrication within the system and will cause premature wear, electrolysis resulting in breakdown of metals within the motor and also if you mix green and orange coolant it will gel and lead to catastrophic failure. This coolant comes pre mixed so you dont have to add any distilled water to your cooling system when using AC Delco Dex-Cool 10-5027/12378390. Non-Silicate formula retains excellent heat transfer characteristics for improved water pump life. Also provides superior high temp protection for aluminum components. The AC Delco Dex-Cool provides effective anti corrosion support by protecting brass, cast iron, steel, solder, and copper components. The AC Delco Dex-Cool was the original fluid that comes in your 6.6L Duramax Diesel, it has been specially formulated for long service intervals, we recommend to service the coolant system every 5 years or 100,000 miles.
