Just another view from outside the box

HI all,
Just purchased a 06 Amarillo. Traded up (or down, how ever you want to look at it) from my 97 F250. I did a lot of research and bought it any way. It has 104000 miles on it and I'm in the process of doing the coolant flush.
Anyway, being and X Deere mechanic, I was just thinking ...... the oil in the engine runs hotter than the coolant. So, could it be possiable that the gelling effect of the (unserviced) antifreeze in the cooler occurs from the (Cooking if you will) extreme differance of the coolant VS oil temp. And over time clogs the cooler, advancing from where the oil is the hottest entering the cooler to the discharge side. Ie;resulting in the mystical 100,000 mile window of cooler problems.

oil cooler problems arent just limited to 100k miles, i think lilpooh on here has changed 3 or 4 oil coolers in 5 years or so and the last two was about a year i think hopefully he'll chime in

Not likely. under normal conditions the oil is less than 15 degrees hotter than the coolant whereas in the egr cooler the coolant is trying to pull the heat out off exhaust gasses that can easily exceed 1200*. Heck I have seen 1600* if only briefly. That is where the real temp difference comes from.

How does this apply to EGR cooler deleted trucks?? Since the coolant will not take on the heat of the exhaust one would expect to see lower ECT correct??
