My recommendation for a cooler is (obviously depending on what your doing with the truck) is get one appropriate for what you will be doing. As i have stated numerous times before, i bought this for our 2004 2500 Hemi/545RFE/4.10's & towing our 10,500 lb Toy Hauler. To help keep it from self destructing when towing our camper (I also put a 1 ton 24 row trans cooler on that truck). I wasn't sure so i went with the biggest they had. I wanted one that was 1.5" thick as well & with the turbulator coil. He said the cooler does not care what fluid is going through it, & also said it would be fine using a trans cooler for engine oil. If you get one, check out summit racing, they were $10 cheaper & free shipping. The one I have is really too big for my application now, but it's what i got, & i will re-use it. It holds about 1.5qts more oil installed. More oil does mean you can go longer between changes I suppose but i don't. I also don't worry too much about the oil changes. I usually use the 15,000 mile Mobil 1 & change it when the weather is nice. It has only 46k on it. Depending on how hard i'm using the truck, oil changes are only about 1x per year, 2 at the most. But now that we are both retired, it will be more often once we start traveling. Every 5-10k miles should be fine.
As far as temp drop, all i can say is that when it was on the 04', we hit a long steep grade in Ky, on our way to Tn. I didn't want it shifting back & forth, so at the bottom of the grade, I literally put it to the carpet & held it there, for the entire hill. Hemi was just a singin'. About 15-20 min later, we hit the top doing about 70-80 with our Toy Hauler. Had to pull over & wait for the Father-in-Law. About 25 min later he pulled in. He had an 04' Chevy 2500 HD w/6.0L/4.10's & HD cooling pkg, pulling a 6300 lb camper. He said as soon as he hit the bottom of the hill, his temp went up quickly. Went right up to the red but not into it. He slowed down to 15-20 mph to finish the hill. My factory temp gauge only went up the width of the needle (coolant temp) & I could put my hand on the engine oil cooler fins with no burning. Same with the trans cooler. My current PW has only gone up about 1/8"- 1/4" tops when towing, with no cooler---even with the 10,500 lbToy Hauler we had. But the G-56 plays a part in that too, i would think. Keeping a gas engine in it's "happy spot" when towing (especially heavy) is key. Lugging a gas engine makes it work harder, as does a constantly shifting transmission. I am also gonna put these on at some point as well:

Not sure what purpose the checkball/spring serve if it is a 100% full flow ?
