I just finished a radiator swap from my oem to a champion radiator 3 row
I also filled with fleetcharge sca pre filled coolant
I put a new motorcraft thermostat and gasket in as well as scraped all the forma gasket off the housing and cleaned out the slot for the little ball to move feely.
I also put on a new napa 4070 coolant filter on
I tested it all yesterday and it worked perfectly but after work I checked my coolant freeze point with a fractometer or whatever that fancy tool is called. I was at -10 below and I like running my stuff to at least -45 below since I live in montana.
I pulled coolant out and got it to about -40 below and called it good for the day. I headed home and it worked perfectly.
(I took it out and ran up a 5% grade yesterday that 2 miles long and the needle moved a needle width from where it had been running and that is the low end of the sweep of the gauge.)
I went out to get stuff out of my truck after about 45 min of sitting I noticed a small puddle of something that had dried recently from under my truck. It looked like coolant because in 45 min it just left a wet spot and I feel like any oil would have left more of a residue. I then checked and saw no leaks. I decided to take it on a drive and see how it was. I got about a mile from my house and then noticed the needle had moved to just under the n in normal and basically stayed there for the next 30-45 min of my driving to see if anything would change. A buddy of mine thinks there may be an air bubble under the coolant temp gauge sender but idk. and I have to drive 4 hours home tomorrow with it. Any help is much apreicated.
