QuestionI understand there is a way to refill the cooling system after it has been drained which is designed to minimize trapping air in the system. Can you describe it?
Answer
Answer: Starting with a system that has been drained via the radiator:
Close radiator drain, hand tighten only
Install cylinder block drain plugs if removed earlier (located behind each exhaust manifold)
Attach one end of 1/4 inch ID clear hose that is 4 feet long to the bleed valve on the thermostat housing. Route the hose away from the accessory drive belt, drive pulley, and electric fan. Place the other end into a clean container. The hose will prevent coolant from contacting the accessory drive belt when bleeding the system during refill operations.
Open the bleed valve
Slowly fill coolant fill coolant pressure bottle until a steady stream of coolant flows from hose attached to the bleed valve.
Gently squeeze upper radiator hose until all air is removed from system.
Close bleed valve and continue filling to the top of the coolant deaeration pressure bottle.
Install cap on coolant pressure bottle
Remove hose from bleed valve
