Draining Procedure
Caution: With a pressurized cooling system, the coolant temperature in the radiator
can be considerably higher than the boiling point of the solution at atmospheric
pressure. Removal of the surge tank cap, while the cooling system is hot and
under high pressure, causes the solution to boil instantaneously with explosive
force. This will cause the solution to spew out over the engine, the fenders,
and the person removing the cap. Serious bodily injury may result.
- Park the vehicle on a level surface.
- Remove the coolant pressure cap.
- Raise and support the vehicle. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Place a drain pan under the lower radiator hose.
- Remove the lower radiator hose from the radiator.
- Drain the cooling system.
- Inspect the coolant.
- Follow the appropriate procedure based on the condition of the coolant.
• | Normal in appearance--follow the filling procedure. |
• | Discolored--follow the flush procedure. Refer to Manufactures instructions. |
Filling Procedure
- Connect the lower radiator hose.
- Lower the vehicle.
Important: Use a 50/50 mixture of DEX-COOL antifreeze and deionized water.
- Slowly fill the cooling system through the upper radiator hose with a 50/50
coolant mixture until the coolant comes out the coolant air bleed hose.
- Fill the radiator with coolant through the surge tank opening to the full
line.
- Install the coolant pressure cap.
- Start the engine.
- Run the engine at 2,000-2,500 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.
- Top off the coolant as necessary.
- Inspect the concentration of the engine coolant.
- Rinse away any excess coolant from the engine and the engine compartment.
- Inspect the cooling system for leaks.
