Hello,

If i have a drain/refill system. Would it be good that after the leak test i drain it and refill the whole system (for cleaning purpose) ?

Thanks.

I don't see the point of draining and refilling again if nothing changed in the loop.
If you want to clean it, disassemble the loop, flush your radiator and blocks and then rebuild.
