Topic: Effective, 'invisible' securing of thermostats

  Posting a solution not found on forums to address the problem of canting of stats in the top radiator hoses that is 'invisible' and has proven to be effective in multiple flatheads. This was given to me by a true artisan of flathead engine rebuilding that has multiple 990+ scoring Fords. His solution stunned me with its sheer simplicity but perhaps many of you already employ the same technique. Simply purchase/obtain a foot of Gates 24024 1 1/2" radiator hose (or equivalent) and cut 2 sections off of adequate length to fit ON TOP OF the stats and INSIDE the existing top radiator hoses to just reach the inner front and rear side bends of the top hoses just above the stats. This is a very stiff hose that is somewhat difficult to insert into the top radiator hoses but with a slight coating of coolant and a bit of ooomphh and creative coaxing will slide in square. Insert these sections into the top radiator hoses about 3/4" past flush with the bottom of the radiator hoses, taking care to orient the front and rear sides of the sections if necessary - my sections are 'square' which has worked very well and held position through multiple stat changes. Then install the top radiator hoses over the stats and onto the head flanges with perpendicular gusto and work the hoses down to the bottom seat of the flange (will require a bit of effort as the Gates sections will effectively be pushed further up inside as the top hoses are pushed down over the Gates' hose sections, stats & head flanges). Install your preferred hose clamps in the original locations and no additional hose clamp above the stat is needed - the solution is invisible for judging, etc.. For what it's worth - proven immeasurably helpful for me. Hope this is of benefit to others.
