WARNING: This page is about a different car, the 2009 GMC Sierra and 2009 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.
    CAUTION: The procedure below must be followed. Improper coolant level could result in a low or high coolant level condition, causing engine damage.
  1. Install the generator control module coolant pump hose. Refer to Generator Control Module Coolant Pump Hose Replacement (Pump to Pump)  or Generator Control Module Coolant Pump Hose Replacement (Pump to Radiator) .
  2. Using the J 38185  , reposition the generator control module coolant pump hose clamp.
  3. Install the generator control module coolant inlet hose. Refer to Generator Control Module Coolant Inlet Hose Replacement .
  4. Using the J 38185  , reposition the generator control module coolant inlet hose clamp.
  5. Lower the vehicle.
    6. NOTE: Use pre-mixed Dexcool only. Pre-mix DEXCOOL contains the proper 50/50 mixture of DEXCOOL and de-ionized water necessary to prevent corrosion damage to the generator control module internal heat sink. Never use tap water in the hybrid cooling system.
  6. Slowly fill the cooling system with the pre-mixed DEXCOOL. Refer to Approximate Fluid Capacities .
  7. Turn the ignition ON.
  8. As the cooling pumps run, air will purge into the surge tank and the coolant level will drop. Top off the coolant as necessary until the coolant is maintained at the Cold Full line.
  9. Inspect the concentration of the generator control module coolant using the J 26568  .
  10. Install the coolant pressure cap.
