You know on the water bottle you have two hoses coming from it, one goes to the top of the engine the other connects to something underneth the bottle. Well my question is the top hose is quite thin and i have got rid of it and put a much thicker silicone hose in its place will it work ok ? say if i just put an extra bit of water in will it be ok ?

Cheers peeps

thats the return pipe, i would say it cant hurt being any thicker

 

Cheers dude
