2001 7.3 f350 coolant gauge stays cold

[dustin6189]

just bought an 01 f350 and the coolant gauge stays about 1/3rd of the way up. even after driving for an hour it wont go any higher. Ive replaced the fan clutch it was toast, t-stat, new coolant temp sensor bwd wt763, and radiator cap and flushed the system and nothing changed.

Used my sct tuner for my 6.0 to run a data log and she started out -40 the worked her way up to the 200. not overheating, no loss of power, no loss of coolant, and no steam. Ive pulled my 6.0 and rebuilt it but this ole 7.3s gauge is starting to bug the hell out of me

need coolant temp sensor #F65Z-10884-AA. But, your "reading" is about par for these trucks. Mines' stay 1/8 above the first mark.

So it's normal for these old trucks to read a little lower? I'm in the navy and a few years back we had 7.3s that did the same thing I just figured it was from the operators beating the living day lights out of them.

Unless the PO of my truck ,was in the Navy, its a normal value reading that i can tell..buddys' truck sits at same marking too...
