Gary, very helpful tip on how to hold the thermostats in place with out garbaging up the hoses with clamps....I like it! LouB.If you want to keep the stock look with just 1 hose clamp you can obtain a piece of thin brass shim stock and cut some narrow strips. Place the strips equi-distant around the top of the t-stat and solder in place. Then fold down the ends of the strips to fit around the outlet. When you install the clamp it will hold the t-stats in place as the rubber will readily conform to the shape. I usually use 3 or 4 tabs depending on the configuration of the top of the t-stat.
