Temp questions??

Hey guys posting some temps think my oil cooler is pretty much screwed but want some quick opinions before i take the plunge

Ambient temp: 45deg f
ECT 184 // EOT 205 @ WOT
ECT 184 // EOT 201 65 mph cruising after WOT run

I know the ECT is a little low but that shouldn't affect the delta correct?

Thanks in advance for the help

Put a thermostat in it and then go on your 65 mph test run without and WOT runs.

It will to an extent. Mine runs around 184-186 with an oil temp of 187-191 pretty much all the time.

So from looking at those temps that you run I guess it is safe to say my oil cooler is definitely pretty much shot as well as a sticking t stat?

i'd try the t-stat first and go from there.. throwing parts at a 6.0L can get expensive.. if your going to replace the oil cooler i'd go with a bullet proof one just so you know your safe.. and what coolant are you running?

As of now, yeah, looking like a cooler but I've seen posts on here where a thermostat letting the coolant run at the right temp brings the delta closer together. Just never know, but the t-stat is easy enough to replace to check that out.
