1st off thanks to all that assisted in this transition to CAT Coolant.
Purchased scan gauge II to verify puking 11 - 15 deg differential.
Had Ford Tech Buddy replace oil cooler and flush with Ford VC-9 reported a bunch of black flakes that mashed to the touch.
Got it home removed lower radiator hose and installed Fumoto valves drained and got this....
Flushed once with 1/2 gallon of Restore and got this.....
Flushed again and got this...
Flushed twice with Restore + and got a lot of milky fluid first time, a whole lot less second time and final flush with 4 Gal Dist. water until clear.
Removed the Starter to install Pass. Valve PIA upper bolt requires 1/2" socket and mini 2 1/2" long handle ratchet with 6" extension.
3/8" ID Clear hose from Lowes makes draining engine a no mess process.
I captured almost 1/3 Cup of sand and metallic flakes
Installed Sinister external Coolant Filter so it will be interesting to see what it captures now.
Refilled with 3 Gal CAT Coolant & 2 Gal Dist. Water.
Running 193 and 195
Again, thanks to all and whomever feels they don't need this should just look at the pics.
