    Hi guys

    I have drained down my system, done some pipework, and installed a new radiator. When filling and flushing the system for a 2nd time, I noticed sludge in the new radiator. I am thinking of adding sentinel x400, fill up and leave it for a few weeks and then flush it. My question is does the x400 act as an inhibitor? or must I add the x100 too ?

    Can give you the answer you are looking for, but you will be better to go on Sentinel Website and read the instruction for X400 and X100

    If it were me I wouldn't bother putting x100 in if only for 4 weeks.

    No, X400 is a cleaner and must be throughly flushed out after use

    The decent cleaners usually have a dash of inhibitor in so they dont corrode your rads whilst cleaning them.
    But then again most of them are brownish liquids - so you'd never know if they were rusting your rads either. Sneaky huh?
