Need a special tool to remove oil cooler

(2006 Mercury Mountaineer)
I’m trying to get the old oil cooler off I need a special tool to remove the sleeve that the oil filter screws onto. I don’t know the name of the tool and neither does autozone. Please help it looks like a bolt head can go in there to unscrew it.

Allen drive fasteners (bolts) have six sided (female) heads - which would resemble the head of a bolt.

Google > Allen drive bit socket - now that doesn’t give you the correct size you’ll need - it is just for reference purposes.. You will have to to the rest.

Good luck!

Also note this is only in reference to your statement:

“it looks like a bolt head can go in there to unscrew it“..

That would require hexagonal - ALLEN DRIVE..®️ tool of the correct size.

I'm assuming this is a 4.0L V6 - as you did not mention which engine you have.

According to the shop manual instruction, It merely states to "loosen the threaded insert". There is no special service tools indicated in the Ford shop manual, which would absolutely be listed if the tool was somehow special.

Sitting here at my computer and not under your Mountaineer, I cannot describe which tool you need, but I'm fairly certain it is a wrench of some sort that most auto technicians would have in their "standard" box of tools. I would suggest taking a photo of the "threaded insert" and taking it to a local shop near you to get some direction.
