How full do you fill the radiator coolant for a 95 Pontiac grand prix?

For a 1995 Pontiac Grand Prix, you should fill the radiator coolant to the full mark indicated on the coolant reservoir, typically around the "Full" line. Ensure that the engine is cool before opening the radiator cap, and add the coolant mixture of antifreeze and water in a 50/50 ratio. It's important not to overfill, as the coolant expands when heated. Always check the owner's manual for specific recommendations.
