Good to know.
Pedro also pointed out that flushing the coolant needs to be done precisely, if any air is in the system the original and probably brittle coolant tank with split within a year or so.
Might have been coincidence but that's exactly what happened to me. I ended up spending $1,000 on the flush and new tank within 12 months of each other, I probably should have done the watermpump then too.
