Bleeding gilera runner water system

Hi guys can anybody help me i dont have a clue how to bleed the water system on my runner 50.

 

I think the bleed nipple is on the cylinder head, not sure if its on the pump itself as I only bled my old gilly 50 once and I done it the incorrect way by just filling the water tank and running the engine with the water bottle cap off for a few mins, then topped it up.

Although that did work and the bike never overheated, its still not the correct way, do a search!

 

fill the collant, leave the cap off, on the top part of the head (the highest point) theres a nipple, undo it and air will hiss out, wait til you have a continuous flow of water from there ( no air what soever then tighten it), then top the collant bottle back up to where it should be

2 min job

 

Ahhh yea I thought thats the way to do it,

Just like bleeding the radiators at home really lmao

 

cheers for the replies lads!
