What's your problem that I use a torque wrench? You had the same type of comments because I used a torque wrench on the rear spindle nut instead of just standing on a bar and guessing.
Obviously shops must laugh about using a torque wrench too which is why people have problems with bolts/nuts falling off, and finding things cracked or bolts stripped or over torqued causing the bolt to break on removal.
Years ago I had the dealer change the oil. They over torqued the drain plug causing it to leak. So, I had to have a shop replace the oil pan. The book says you have to remove the oil cooler to change the pan.
So, that shop must not have torqued the shaft on the oil cooler enough. As recently, that piece unscrewed when I went to remove the oil filter. So, I figured it best to torque it to spec since I already have a torque wrench.

I had the oil pan replaced a while back because the dealer over torqued the drain plug causing it to leak. So, the shop must not have torqued the shaft down enough when they put the oil cooler back on after replacing the oil pan. As it unscrewed when I went to remove the oil filter later on.

I appreciate it. I was going to guess 20 ft/lbs.

The center shaft of the cooler freely rotates to press the cooler up to the block but I don't remember the cooler rotating while it was tightened. That's because of those studs locked into the adapter.
I'd check to make sure your adapter is tight.

Are you sure it wasn't the oil adapter above the cooler? IIRC, there are studs that prevent turning of the cooler itself. I'm thinking (though probably wrong) that the adapter itself would have to be turning because of the studs "locked" into the adapter.

The cooler body wasn't turning. It was the center shaft that was turning. The center shaft screws onto the adapter just like an oil filter. When I was unscrewing the oil filter, that center piece unscrewed instead. So, I kept unscrewing it until the cooler dropped down. Luckily the shaft is just held in place with a snap ring. So, I got it off and removed the oil filter without having to remove the cooler and drain the block. That snap ring looks to serve no purpose as there is no groove in the shaft for it. Must have been on there for assembly to keep the shaft in place.
The only thing holding the cooler on the adapter is the torque on the center shaft piece. I probably should have replaced the cooler gasket while it was dropped. I think most just use the gasket off an oil filter.
I've got the center shaft in the cooler screwed down on the adapter. I just needed to finish torquing it.

It's not the adapter on the block. I must have miss-worded my post when calling the cooler an oil cooler adapter.

When I was unscrewing the oil filter, that center piece unscrewed instead. So, I kept unscrewing it until the cooler dropped down. Luckily the shaft is just held in place with a snap ring.

Sounds like you've got a handle on it. Obviously, you just need to torque the adapter a hair more than your filters.
