I just got my Edge CTS in the mail today and couldn't wait to hook it up and see what was going on with my truck. I have a 03 6.0 with 119k miles that I just bought a few months back. I installed a coolant filter and I am running Mobil 1 5/40 diesel oil with a motorcraft oil filter and cap. Recent coolant flush also with G05.
Here is a pic after 10 min of the CTS hooked up.
This pic is after a 5 min highway run at about 70MPH.
The last pic is when I was almost home, I live 10 min from the highway.
The ECT seems ok, maybe a tad on the high side but couldn't that be caused by high EOT? I am thinking my oil cooler is starting to get clogged.
