5. Slowly fill coolant reserve/recovery bottle to at least the FULL HOT mark with the recommended coolant. It may be necessary to add additional coolant to the reserve/recovery bottle after three or four warm-up/cool down cycles to maintain coolant level between the FULL HOT and ADD marks; if any additional trapped air was removed from the system.
