COOLING SYSTEM BLEEDING
Close drain valve at bottom of radiator. Reconnect coolant inlet hose to engine oil cooler. Add coolant to radiator until clear coolant (no air bubbles) comes out of air bleed screws. Tighten air bleed screws. Wait 2 minutes. Add coolant to radiator as necessary. Install and tighten radiator cap. Fill coolant recovery reservoir. Run engine. Allow engine to cool. Check and fill coolant recovery reservoir as necessary.
