Does another hose feed the oil cooler, or does it feed through the block. I have a 99 Mustang Cobra, but adding a KB supercharger added a lot of hoses for the intercooler. You are right, cannot see crap.
Hopefully you have another hose feeding coolant to the oil cooler.

If you have access to a lift, it might not be too difficult to remove and investigate, fix. Only issue you might have is no oil cooler function.
Does the cooler attach under the oil filter?

Huh, since when were those available again?!
Looking last year and could not find them. Ended up deleting it.
I do not know about the availability, just posting to get a look at what is involved. Was your cooler defective, stopped up or what?
Your experience might be helpful in what to look for.

Probably not had pieces of my piston, rod and block in it. Just saw that post and got pissed off they have them now but 03-04 cobras are different due to the low mounted alternator.

FWIW it's obviously a flow restriction up stream of that hose. Honestly I'd pull the t-stat and see if anything changes. The cooler if like the 03 attaches to another piece behind it that has a passage to the block.

That is part of main coolant circuit and it more than just the cooler. IIRC it's actually to heat the oil faster during cold starts. Honestly car isnt here right now so hard to tell the order of things without looking at a 4V.

The external thermostat housing should feed to the oil cooler from the radiator/overflow (open loop) or bypass hose (closed loop) depending on the thermostat being opened or closed.

You can rebuild your oil cooler with a new set of seal rings.

What happens to the hose when it first is started up?
I.E. closed loop before the thermostat opens up and enables the radiator path?
