WARNING: This page is about a different car, the 2004 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
To avoid being burned, do not remove the radiator cap or surge tank cap while the engine is hot. The cooling system will release scalding fluid and steam under pressure if radiator cap or surge tank cap is removed while the engine and radiator are still hot.
- Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
- Place a drain pan under the drain cock.
- Open the radiator drain cock.
- Drain the cooling system.
- Lower the vehicle.
- Remove the coolant pressure cap.
- 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 Flushing .
IMPORTANT:
Draining the cooling system with the pressure cap installed will syphon the coolant from the overflow tank.
