Not going to make it this year because right at this moment my pinto project Garage is being built , so I have things all stacked out of place , next year i can make it , and the year after i know i can because i will be retired , the fan pulley I would leave stock , too small is hard on that one belt , along with the bigger fan , I found it this weekend , but have to move a pile of things to get to it , will mail it to you when I start moving into my new garage , and the electric gauge does not tell you much where you at when your under a load , I have a small gauge in mine and runs 198 most of the time , I have a 195 thermostate in mine for gas mileage , sill have the idiot light also , it blinks once in a while when I am towing up a long long hill , temps around 210 , and drops quickly , may just try the 180 degree thermostate when I change the coolent , do it every three years to keep up the cooling system , will also convert to the three belt water pump pulley set up then of the 2.8 bronco II , in case that one belt sanps and toast the engine ,
