I have a set of SFS hoses and heard the you need to bleed the system if you replace these?
How do you bleed the system?

Thanks

Fill the system up slowly through the header tank until it won't take any more. Leave the cap off and start the engine. The water level (don't forget the antifreeze...) will drop as the water pump circulates it - keep topping it up. When it stops dropping replace the cap. It won't take long to fill and if you leave it too long there will be a rush of water out of the tank as the thermostat begins to open so a minute or so will likely be enough. Check the level in the expansion tank next to the battery. Run the engine for a while and allow to cool. Remove the header tank cap and check the level again, topping up if necessary (it should be full to the top). Coffee time
