Draining the Cooling System

DRAINING THE COOLING SYSTEM

1. Remove the cap from the expansion tank.

2. Loosen the clip at the bottom of the radiator inlet hose and remove the hose allowing coolant flow out.

3. With hose uncliped put a hose into the expansion tank and block the remaining gap with your hand to creating an air tight seal - flush system until water runs clear. This should take about 6 minutes.

4. Undo the expansion bottle tie clips and hold it up as high as you can.

5. Reconnect bottom hose and do up the clip.

6. Unscrew bleed screws on the top hose and heater hose so that they are nearly totally out

7. Fill cooling system with 50/50 water antifreeze mix until coolant begins to drip out of one of the bleed screws.

8. Close the leaking bleed screw and continue to add water mix until liquid comes from the second bleed screw..

9. Close second bleed screw.

10. Top up expansion tank to max mark with the bottle in its normal position - if when you bring the expansion bottle down to its original place it is over full, open a bleed screw to let out some of the excess coolant out.

11. Replace coolant tank cap and bleed screws and ensure there are no leaks.

12. Start engine and run until it reaches its operating temperature - If the temperature needle starts to rise very quickly then chances are there in a lot of air in the cooling sytems, this can be solved by opening the bleed screws and watching until no air is coming out of them and just a constant stream of coolant, then you know that you have removed the air and you can tighten them back up. !CAUTION! be careful not to do this when engine is too hot.

13. Stop engine check for leaks - if sound then remove expansion bottle from clips and hold it up as high as it will go

14. Open bleed screws once again to ensure that only coolant comes out and no air. If any air comes out leave them open until only coolant comes through.

15. Close bleed screws, ensure coolant is at correct level.

16. Start engine up, tempearture gauge should rise at normal rate and then keep idling to make sure the fan cuts in at the normal place. If the temparture gauge even goes SLIGHTLY HIGHER than normal and the fan hasn't cut in switch of engine straight away and investigate.
