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
i flushed it out i think i did it right but i did not flush it all out so its orange and green more orange cause i thought i did it right but if not is that the problem the other problem is that i had the green and there every sense i got the car what should i do im lost at this point cause i dnt have alot of money to spend on someone missing it up even more.
