MY CAR HAS BEEN OVERHEATING THE LAST COUPLE OF DAYS BECAUSE IT HAS BEEN HOT OUTSIDE. WILL GREEN ANTIFREEZE INSTEAD OF DEXCOOL MAKE IT OVERHEAT?

1998 Cadillac Deville • 15,000 miles

Will green antifreeze instead of dexcool mess up my engine or make it overheat. I just bought this cadillac deville and it has green antifr4eeze in it and since it has gotten hot outside last couple of days it has been overheating.

We call the red Dex-Cool "Dex Mud" because that's what it can turn into. The green will be fine but it can't be mixed with the red. The system should have been flushed when the change was made.

First check that the radiator fan is turning on. Check the fins on the radiator to be sure they aren't corroded away.
