Caution: Do not remove radiator cap if engine is hot. 1. Check cooling system for leaks, loose connections or worn parts. 2. Remove radiator cap, open radiator and engine block drains, then flush system completely with clean water. For best results use Star brite Radiator Flush to clean system. 3. Close radiator and engine block drains when all water is drained out of system. 4. Fill radiator with desired ratio of antifreeze and water, making sure that the level is slightly lower than the filler neck. 5. Set heater on high and run the engine to normal temperature; the thermostat should now open, releasing any trapped air. If necessary, add more solution to fill radiator. 6. Finally, replace radiator cap and check for any leaks.
