I’m running a Honda 420 and I had the Honda dealer put in a block heater and they did a shitty job of putting the hoses on. Basically I have a slow leak, and I only realized today and my reservoir was damn near empty. I tightened the camps on the hoses and hoping that did the trick. However I had to add some water to the reservoir tank to hopefully mix with what little of the coolant fluid was left. Does it circulate or just sit there? I’m paranoid that the water coolant mixture will freeze (-21c). Driving into town to buy coolant right now

Any thoughts?
