Solar coolant circulator, works great!

Installed a solar coolant circulator in my coolant system and am getting coolant to heat the system faster than I ever imagined. I tried plugging the car in and turned on the circulator and actually took off from home immediately on grease. this means I can get longer driver time on grease and less on diesel! I plan to install one on my Jetta as well.

Discovered why coolant wasn't circulating

I finally got coolant circulating and my Hotfox is heating up as it should. I had thought I had air trapped in my coolant line and that was causing the coolant to not circulate well. It was that but more. My kit came with plastic T's that tap into my 3/4 inch heater hoses and T off to my system with a 3/8 inch nipple. I removed both T's and discovered that the plastic had softened and was deformed by the hose clamps. I also checked the 3/4 inch heater hose and found that it was bent slightly restricting flow. To correst tis I built T's with brass using a 3/4 inch brass T and two 3/4 inch nipples and one 3/8 inch nipple. When I installed this in the heater line I found that it was rather large and wanted to bend the hose even more than the plastic T. I went o Auto zone and purchased some stock 3/4 inch heater hose with some preformed bends that allowed me to make the connections and not restrict the flow of coolant. Now I have my system running and no restricted coolant. I hit 100 degrees at 1 mile vs 3 and switch over around 3-4 miles rather than 8 miles. Chris
