I bought and installed the Needswings seperation kit over the weekend. I was a bit of a bull because I broke off the top nipple of the overflow tank trying to take off the hose. I also broke the two prongs on the sensor, on the bottom of overflow tank. I took it out for a good run cycle and temps where great (83-85F) but S/C wouldn't engage when I kicked it down on the highway, after it had warmed up for awhile. Either the sensor being broken cause the S/C to take it easy or I need a new pump finally. I was going to get the pump at the time I upgrade to a better E/H. I will try and solder the prongs together and see if that helps but I don't have any warning lights, and people have changed out there overflow tanks so I am assuming the sensor does nothing more than provide a coolant level reading.

Has anyone replaced their overflow tank and sensor? $$$?

I was thinking as I write this that maybe I have just had an air bubble that is causing me problems. I will continue to run with the valves open to see if it alleviates itself. Replies welcome
