Any Prius Mechanic near Atlanta for Engine Coolant Change?

I was under the impression that the CHRS pump could cycle when car is off - hence the need to disconnect? Maybe I'm getting this mixed up with some other pump.

 

100% on the OCD diagnosis.

 

My Prius was actually totaled a few years back. I ended up buying it back from my insurance and repairing it. A dump truck rode over the front drivers corner of my car - amazingly the damage was almost 100% superficial. One of my concerns at the time was that the CHRS Tank was partially crumpled/dented....however, no leakage was evident. I immediately bought a used replacement tank with pump but ultimately decided to take a chance and and roll with the original tank.

Well, its been 3+ years and no issues. I've still got the replacement tank sitting in a box. My dilemma has been whether I should replace the tank/pump and do the full engine coolant purge. I figure after at least 2 years procrastinating it's time to finally do something - either have an experienced mechanic do the complete change or, after reading your method, just go ahead and leave the original tank in the car and just drain/refill the radiator.

I hadn't heard of that Redline Water wetter - I'll look into that too.

 

This is the thread that references the pump activating when car is off - but reading it again I think maybe it just cycles immediately at power down. Edthefox can likely clarify.
