New loop with pastel

[sdavlaws]

I will be assembling my first hardline loop with a pastel fluid, just waiting for the last waterblock.

I have ordered a Blitz pro kit to clean to new EK rads out but with it been a new system should i also do the second part with the loop assembled with all the fitting/blocks been new or would just giving them a flush with water be fine to reduce the risk of color changes?

Thanks.

Thanks I was unsure if it was needed for new equipment or just when your changing fluids to get rid of any remnants of the old one.
