OK, first of all, guilty as charged ... just turned 101k and I never changed my coolant. I'm old school from "green" days where you changed your coolant when the engine started to run hot. Long story short my water pump went. I have it torn down right now and yesterday my wife drives the H3 home and I watched it puke red fluid all over the driveway. The trans cooler in the radiator failed. The H3 has 170k BUT a replacement radiator! Guess what ...Dexcool! SO now 2 vehicles down due to Dexcool. I have a 1953 Ford with green stuff from the 60's and it runs perfect. I don't want to hear use "Motorcraft" it was designed for that. BS! I'm an engineer and believe in science. There is MUCH better fluid and parts than those stamped "Motorcraft".
Stepping off my soapbox ...
Does anyone run a coolant other than Motorcraft Orange (not counting those with Green originally)? I saw Makuloco's video on Motorcraft Yellow which is PHOAT and that has me intrigued as the Asian car makers have been using PHOAT for decades with great success! There is also a lot of universal stuff that has guarantees not to corrode aluminum or degrade rubber & silicon.
Sorry to stir the pot as it is a very touchy topic with not a lot of good info online other than marketing propoganda. I'm looking for real-world usage from this forum since I need to flush and refill here soon and I am sure as hell not putting Motorcraft Orange back in!
