    My 458 pressure cap bleeds fluid and needed replacing.

    If your does the same you don’t need to buy from the dealer. You can order the exact part from Alfa Romeo part number 46556738. It costs $10.

    I read a while back that the coolant leaking out is actually normal on the 458 and it is basically the coolant tank equalizing to the appropriate level.

    First, is this true?

    And second, if true would this Alfa Romeo cap cause issues?

    Take a look at your coolant tank also. When my indy was going to change the cap, found the tank deteriorating significantly. Changed both, disaster averted. Good catch by my indy.

    Alfa & Ferrari seem to have the same part number for the cap if am correct so surely has to be the same as the one Ferrari would supply you lol
