Overheating issue

[dyoung14]

Seems like my new truck runs way to hot, easy i mean EASY driving it runs around the N-O on the gauge but if i start driving it a little hard like 70 mph or so it will hug the M-A if i run it up to 80+ mph not even for very long it will head past the L on the gauge,

Coolant looks clean, fan feels tight and it seems like i hear it, i bought a thermostat today its a 205 degree, havent changed it yet guess i will tomorrow, the truck is a 1995 F350 ext cab 2wd DRW 5 speed, has 290,000 on the old stroker, not sure if the motor is origanal probly is, i ordered o rings last night from diesel orings.com, i was going to drive to beans and buy some, but they wanted 120 dollars for them so instead i ordered the same exact part for half the price this thing is using a ton of oil so that has to be fixed asap, i think the turbo is going to need rebuild it seems like the compressor housing is staying wet even if i wipe it clean,

so any ideas on the cooling issue?

I think you shouldn't trust those factory gauges.
They aren't worth a crap. Get a real gauge and see what it's doing.
