The KL5005NAV Vacuum Module uses standard shop air to create negative pressure throughout the cooling system, drawing the coolant through the entire system from the bottom-up. This eliminates the possibility of air pockets forming in the EGR cooler.
PROCEDURE:
- With the Tank Valve turned to CLOSED, connect the Vacuum Module to the Cap Adapter.
- Turn the Blue Vent Valve to the CLOSED position and attach clean, dry shop air.
- Open Air Valve on the Vacuum Module and allow the vacuum to draw 20"-25"hg on the cooling system.
- Once the Vacuum Module reaches the green zone, set Tank Valve to FILL position.
- Watch coolant level in Storage Tank. When Tank is nearly empty, turn Tank Valve to the CLOSED position and turn off the Air Valve.
- Open Blue Vent Valve to release vacuum. Disconnect the Vacuum Module and remove the Cap Adapter.
- Add coolant and fill to proper level. Replace surge tank cap.
