To replace the antifreeze in a 1985 Cadillac Seville, start by ensuring the engine is cool and then drain the old antifreeze by removing the drain plug on the radiator or using a siphon. Next, flush the cooling system with water to remove any residue, then close the drain plug. Refill the radiator with a 50/50 mixture of antifreeze and distilled water, ensuring to also fill the overflow reservoir. Finally, run the engine briefly to circulate the new antifreeze and check for leaks.
