How many gallons antifreeze/coolant does 1996 Sedan DeVille take ?
The capacity of the deville cooling system is 12.3 qts of antifreeze.
It will take approx. 12 quarts of antifreeze to fill it. Two gallons of pre-mix 50/50 should cover it, with it empty. Be sure to put the ORANGE silicate free antifreeze in it and not the GREEN propolene glycol.
That's just over 2 gallons ... & the ORANGE silicate is like $25 a gallon ! ... Hopefully, the GREEN propolene (at $12) won't make too much of a difference.
DO NOT USE THE GREEN PROPYLENE GLYCOL ANTI-FREEZE, IT EATS AWAY AT THE ALUMINUM IN THE ENGINE AND DETERIORATES THE HEAD GASKET.... USE ONLY DEX-COOL 50/50 IN THIS ENGINE AS THE OWNER MANUAL STATES AND YOUR ENGINE WILL LAST YOU AS LONG AS YOU FOLLOW THE MANUAL'S DIRECTIONS ON ALL MAINTENANCE RELATED ISSUES
