I'm replacing a whiney coolant pump on the 646 211.
So I'll do a flush and coolant replacement.
I'm going to drop the coolant and flush with tap water, then drop that.
I've picked up the ECP triple QC concentrate and will use that at approx 50 / 50 ratio for the new fill.
We are in a soft water area and in the past I've just used tap water for this. While some purists will tell me my engine will disintegrate before my eyes what are the real world thoughts?
