. Close radiator drain plug and refill with 50/50 mixture of G-05 antifreeze and distilled water, up to the very top of the radiator.

. Open air bleed screw, where the top radiator hose connects to the engine block, until coolant starts to come out. Then, retighten air bleed screw.

. Replace radiator cap, empty overflow reservoir, refill reservoir to the "Full" line with coolant, and replace reservoir hose and cap.

. Start engine and allow the car to reach normal operating temperature. Check for any leaks.

. Allow car to completely cool down and add additional coolant, if necessary, to fill the overflow reservoir to the "Full" line.
