Filling Procedure
WARNING: This page is about a different car, the 2017 Cadillac ATS. 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.
- Slowly add a mixture of 50/50 DEX-COOL antifreeze and clean drinkable water to the cooling system through the radiator surge tank filler neck and through the top of the lower overflow reservoir as well. Refer to Approximate Fluid Capacities .
- Slowly fill the cooling system until the coolant level stabilizes at the FULL COLD marks on both the surge tank and overflow reservoir.
- Start the engine and allow to the engine to idle in PARK or NEUTRAL with the parking brake engaged.
- Slowly fill the coolant mixture until the coolant level stabilizes at the FULL COLD mark on the surge tank.
- Install the surge tank cap and close the cap on the coolant overflow bottle.
- Run the engine RPM to 2000-2500 rpm until the engine reaches normal operating temperature.
- Allow the engine to idle for 3 minutes.
- Shut the engine OFF.
- Allow the engine to cool, remove the surge tank cap and open the overflow reservoir cap, and repeat steps 1-8 until the coolant level has completely stabilized at the FULL COLD marks on both the surge tank and overflow reservoir.
- Remove the surge tank cap.
- Inspect the concentration of the engine coolant using the J-26568 Coolant and Battery Fluid Tester.
- Install the surge tank cap.
- Inspect and if necessary, fill the surge tank and overflow reservoir as necessary.
- Rinse away any excess coolant from the engine and the engine compartment
- Inspect the cooling system for leaks.
