[HVAC]

I've been running a Maze 1, Hayden Trans Cooler, and 180gph pump for 4 years now, 24/7 365.

I usually replace the water once a year. Never had any evaporation or leaks so I've never had to refill it.

Maintenance free is my game.

I'd like to cut open the block and examine the corrosion inside, but if it still cools well, I see no need.
