2003 F550 4x4

Hello.

I am starting my 6L after it sitting for 26 months. Replaced the stater charged batteries both. I have pulled the fuel tank replaced the fuel with new fuel. I am going to change the oil with new 5w40 conventional diesel oil. Is there anything else I should do before I turn the key ?

Check ALL the fluids, and inspect for mouse nests. That’s a long time for that truck to be sitting.

Squirrels would chew wires on my old 7.3L when it sat for even 6 months.

You need to load test those batteries after charging them.

Yeah I have some very industrious chipmunks here. They like to setup shop in my tractor every so often. They have reeked havoc on fuel lines and trailer wiring.

Yes I load tested the batteries. I have changed out the fuel by dropping the tank cleaning it out reinstall and put in 10 gallons of new diesel. Going to town tomorrow to pick up oil and do an oil change. Put on a new starter. (It was weak when I last drive it). It is a 6 spd manual transmission. Should the colant be OK?

I would recommend making sure you had an EC-1 rated ELC coolant in it.

Either that or make sure you flushed out the old Ford Gold every 40k miles, AND made sure you never got it over 215*F by the ECT sensor.
