Key Features and Benefits:

› No moving parts. Uses Shop Air to extract or inject coolant from the vehicle.
› Easy to operate Control Manifold to create vacuum or pressure to the Tank.
› Automatic Shut-Off Valve to prevent injecting air into the cooling system.

Extract Coolant

  1. Remove Vehicle Surge-Tank Cap
  2. Connect shop air (regulated to 90 psi max) to manifold
  3. Close in-hose ball-valve (A)
  4. Place control manifold in vacuum mode (B)
  5. Connect hose to cooling system Q/D Fitting
  6. Open in-hose ball-valve (A) to extract coolant
  7. Close in-hose ball-valve (A) when extraction is complete
  8. Disconnect hose from cooling system Q/D Fitting (E)

Inject Coolant

  1. Remove Vehicle Surge-Tank Cap
  2. Connect shop air (regulated to 90 psi max) to manifold
  3. Close in-hose ball-valve (A)
  4. Place control manifold in pressure mode (C) up to 25 psi
  5. Connect hose to cooling system Q/D Fitting (E)
  6. Open in-hose ball-valve (A) to inject coolant
  7. Tank will shut-off when completely empty to avoid injecting air into the cooling system
  8. Do not over-flow cooling system surge-tank
  9. Close in-hose ball-valve (A) when injection is complete
  10. Disconnect hose from cooling system Q/D Fitting

Eliminate Trapped Air

  1. As part of the Injection step, take these additional steps
  2. Stop injecting coolant when a few inches of coolant reaches the Surge Tank. Close in-hose ball-valve (A)
  3. Disconnect hose from cooling system Q/D Fitting (E)
  4. Attach Retro-Fit Stopper Handle to hose (F to E)
  5. Clamp off any vent hoses/connections to the Vehicle Cooling System
  6. Place control manifold in vacuum mode (C)
  7. Seal Retro-Fit Stopper over Vehicle Surge-Tank opening
  8. Open in-hose ball-valve (A) to apply vacuum
  9. Watch air bubble in the Surge Tank as trapped air is removed from the cooling system
  10. When air bubbles stop, close in-hose ball-valve (A)
  11. Relieve vacuum on Surge-Tank and remove Retro-Fit Stopper
  12. Replace Retro-Fit Stopper Handle with Hand Valve (G to E)
  13. Place control manifold in pressure mode (B) up to 25 psi
  14. Open in-hose ball-valve (A)
  15. Complete filling the Surge Tank using Hand Valve
