What's the chevy express coolant type?

The kind of coolant You should use for Your 2020 Chevrolet Express is DEX-COOL, according to the manual. This kind of coolant is designed to stay in the vehicle for up to 5 years or 150,000 miles - whichever comes first. The price range for the antifreeze will be from about $15 to $30, depending on which brand You prefer going with. To check coolant levels, make sure the car is on a level surface beforehand. Do not open the coolant cap if the liquid is boiling. If the coolant is visible, but falls below the mark on the tank, add A50/50 mixture of drinkable water with DEX-COOL into the tank - but be positive its cool, or You could seriously injure Yourself or someone near You.
