Fill the radiator through the coolant resivour, which is on the passenger side engine compartment.
You have to fill the overflow tank as the radiator does not have a fill cap. Run the engine as you fill the overflow tank but just up to the marks on the tank.
Coolant goes in the radiator or you can also fill the radiator resevoir.
You use the coolent reservoir bottle to fill the radiator. It should fill the rad before it fills the bottle.
Many VW Beetles from '98 to '05 don't have a traditional old-school radiator cap. The radiator fluid usually is poured into the radiator fluid recovery bottle. There should be a fill line on the bottle.
Let the engine cool and press down and twist the radiator cap to the left to remove it. Fill the radiator to the top and reinstall the cap. Check the coolant level in the overflow reservior and fill it to the fill line.
