the silver and nickle thing... much debate over this and IF it was a major issue 1) a LOT of vets would have trouble waaaaaay too often and 2) EK would not support warranty even if you use silver kill coil. Using a kill coil DOES NOT void warranty. They just suggest not to use it (mainly because they are doing the CYA thing after their last fiasco with shoddy plating.
You either have caused damaged by using the wrong coolant (never use automotive coolants as mentioned above) or there was shoddy plating on there in the first place (which if it was an EK block does not surprise me even to this day when they say they do it different. They were far too eager to blame users than accept they messed up)
From a thread yesterday, and EKWB rep (bit of a .... well... you'll see) stated they will still honor warranty. However, using the wrong coolant was not addressed, and THAT may void it in the end
