  could some one send me a picture of the right thermostat for 41 ford or the correct part number for it thanks


Old Henry    -- 06-29-2015 @ 6:42 PM
  The stock part number is 11A-8575. Pictured and available here: http://cgfordparts.com/ufolder/cgcat.php?searchtype=Search+%23&year_choice=41&searchtextdesc=thermostat&searchnumber=11A-8575&sp=Search+%23

But, a higher flow thermostat that fits in place of the stock one is NAPA part number THM 111 here: http://www.napaonline.com/Catalog/Result.aspx?Ntt%3dthm%2b111%26Ntk%3dKeyword%26Nty%3d1%26N%3d599001%2b101990%2b50068%2b2068022

  Me thinks your going to get leaks where "Ole Henry" has the wires . Find another way to hold them in the neck so they don't tilt and use the large opening ones for increased flow when open. OMO. ken ct.

  I think Old Henry's method for securing the stats (not mentioned in this discussion but found easily when searching the forum) will work fine - he's certainly logged more than enough long-distance miles to prove his design's effectiveness! I have tried it and to ken ct.'s point it took a couple or so attempts to make it work for me without leaking. In the end, fundamentally based on personal preference associated with the then thinking I may potentially be changing stats in winter versus summer, I went in another direction.

To Old Henry's credit his creative 'wired-down' method can be made to work with a only a slight bit of effort. As I recall he originally had to tweak his process very slightly to make it fully effective for him.

  Here's the thermostat hold down method that I use that's been referred to.

  I suspect quite a few have successfully used Old Henry's method to retain the stat in correct position. An alternate method which I understand also works is to insert/glue a short piece of straight piece of rubber hose inside the main hose (1-1/2 inch ?) which also prevents the stat from tilting. Apparently neither method inhibit flow.

  lpthompson - we digressed from your original question here.

You asked for a picture and part number for the 'right' thermostat for a '41. What exactly were you looking for, meaning did you get what you wanted from Old Henry's original reply, were you looking for a picture of an 'original' thermostat (versus the modern replacements with the same part number), were you questioning what the 'original' temperature rating would have been for a '41, etc.?
