    Firstly "I'm" and "aren't".
    That is incorrect expansion tank systems are designed to vent. Expansion tank systems can have a higher vent pressure but this is entirely for the purpose of mitigating evaporation which is a pain in the arse in expansion tank systems.

    so i want to do it like this? (attachment) is the pindick hose from under the cap large enough to move enough fluid back and forth?
    i think this with a recovery cap on teh Rad and overflow to ground on the tank will be the easiest option

    So is there a pro and con between the 2 recovery vs expansion? or they basically do the same?

    This is what i have (see pics) so i can ditch the filler that i currently have if need be as its not on the radiator, im just begin lazy. Probably put a blanking cap as it give me options. i also have my water temp sensor in this filler (on the underside)
    and i can jack into the lower coolant line via the aluminium joiner with a 1/2 JIC weld on..

    Header tanks or "expansion tanks" are higher than the system with bleeds back to it and generally has a air pocket in it which is good for engine or rad designs that require it. You can also have a header tank with a overflow in it as in pic 2 which wont have any air in the pressuised side but will act like a standard overflow system but with added benefit of keepingnair out of thw pressure side . These are factory oom setups but arent very common
