Radiator Air Lower Deflector Replacement
|
4. |
Lower the vehicle.
|
5. |
Slowly fill the radiator with a 50/50 coolant mixture until the coolant level reaches the base of the radiator surge tank. Refer to Approximate Fluid Capacities . |
6. |
Allow 30 seconds for the coolant level to stabilize and continue to fill the coolant filler neck until the level stabilizes for at least 2 minutes.
|
7. |
Start the engine and allow to the engine to idle in PARK or NEUTRAL with the parking brake engaged.
|
8. |
Slowly fill the coolant mixture until the level stabilizes at the base of the radiator surge tank.

|
11. |
Turn OFF the engine.
|
12. |
Allow the engine to cool, remove coolant fill cap and repeat steps 4-10 until the coolant level has completely stabilized within the radiator surge tank.
|
13. |
Inspect the concentration of the coolant mixture using
GE-26568
Coolant and Battery Fluid Tester.
|
14. |
Inspect and if necessary, fill the coolant reservoir bottle as necessary.
|
15. |
Rinse away any excess coolant from the engine and the engine compartment.
|
