Hi motobiz, get yourself a copy of Rave, it's all explained in there. In the meantime try this:

Refill
1. Flush system with water under low pressure. Do not use water under high pressure as it could damage the radiator.
2. Fit new sealing washer to drain plug. Fit and tighten drain plug in coolant pump feed pipe.
3. Fit access cover to underbelly panel.
4. Prepare coolant to required concentration.
5. Remove bleed screw from top hose.
6. Unclip the bleed hose from the battery box.
7. Unclip the expansion tank from its mounting bracket, remove the expansion tank cap and raise the expansion tank vertically 10 cm (4 in) Retain the tank in this position.
8. Slowly fill the system through the coolant expansion tank until a steady flow of coolant is emitted from the bleed hole.
9. Fit the bleed screw, then, with the expansion tank still raised, continue filling the system until coolant level reaches the cold level mark on the expansion tank.
10. Fit expansion tank filler cap, fit the expansion tank to its mounting bracket and clip the bleed hose to the battery box.
drain plug sealing washer.
11. Start and run engine until normal operating temperature is reached, and check for leaks.
12. Switch off engine and allow to cool.
13. Check for leaks and top-up coolant to the cold level mark on expansion tank.​
