    I recently had a Western HTS installed on my 07 F150. We have not had much snow but did get out twice to push a couple inches. I did 3 driveways within a half mile of each other than drove about 6 miles to the next one and when I got there there was antifreeze leaking from the thermostat side of the upper radiator hose, not much but steaming like crazy. The temp gauge never moved so I was kind of surprised. I made it home and added a bit of antifreeze then had it flushed and redline added. The next time I plowed same deal when I got to the last driveway about 6 miles from the first 3 this time more as leaking out and it appeared as if it was coming from the back of the engine. I made it home let it cool then went for a drive and after about 6 or 8 miles I stopped to check and it was leaking from the bottom of the upper radiator hose by the t-stat, I tried to move the clamp and it broke in 2 pieces. Has anyone had this issue and since I fixed to clamp should that clear it, Like I said the temp gauge never moved so I don't think it was overheating just too much pressure for the broken clamp. Also when I check at the last driveway the trans cooler was hot to the touch. Any help would be appreciated.

    The stock hose clamps are cheap as hell. I replace them when ever I can. The hose gets moved and they start leaking. Any miles on the truck I replace the thermostat too. Anymore they just fail. No warning! Just move the old clamp away from the area and put a new screw type on. You take to hose off. Make sure you put gasket shellac inside the hose area that makes contact with the sealing area. Use a screw driver to tighten. Socket and ratchet gets them too tight. Breaks the clamp or cuts the hose.

    ^^^^ What he said
    I will often drain a bit of coolant and put some silicone on the inside of the hose and snug it up let it sit a few hours and refill and run.
