Where on a 440 can I install a temp sender. The plug in the front by the water pump will not come out. I tried with an impact and it still wont budge. I am planning on putting a Spal fan on here and need a sending unit to do it. I want to keep the factory hooked up as a backup. I guess I could take the hoses off for the heater and stick in in there as I don't drive this in cold weather. Anywhere else.
