05 F-450 overheats on climbs

[DVCF450]

Hi guys
Happy (almost) New year! I have replaced the T-stat,de gas bottle(and cap), new BPD water pump and BPD radiator. Numerous flushes, with DI water and Zerex EC-1. Six monthes ago installed a BPD EGR cooler. When I climb up the mountain, a 2-4k ft. pull, my oil temps go into the red. 15 to 30 mins. on side of road usually cool it down enough for ne to make it home. I don't tow a trailer, but with full tanks I am grossing around 16.5k lbs. Am I looking at a new oil cooler/heat exchanger again? 156k miles on the odo.
Thanks for your replies and wisdom!

Are you running any kind of monitor or are you just going off of the factory gauges? It sounds like the oil cooler is most definitely clogged. One of the most important things you can have on these trucks is a monitor such as the edge insight cs or cts, scangauge or the dash boss for your iphone (beat you to it Rich). I would definitely stop driving the truck until getting this properly diagnosed or you're risking a very expensive repair.

Thanks Fantom, am going by factory gauge. Edge CTS is on the way, but not here yet. I don't drive with the elevated temps, just pull over safely till it cools down.

Sounds like your in need of an oil cooler and since your already aware of the great products produced by BPD I'd say buy one of their oil cooler kits and never worry about this again.

Thanks Tuscany. Always great to see your truck and read your replies. BPD is indeed a terrific company, and remoting the oil cooler is something I have been drooling over for some time. This year is the first, since i bought this truck in NOV04, that I have been doing my own work in the driveway. Had to take it to the dealer for some diagnostic repairs, but routine stuff I am becoming more comfortable with. Many thanks to this forum for helping me get over my fear of the 'mysterious' diesel!
I can't say I relish removing the Turbo and intake manifold again, but if thats what it takes to get my daily driver back, so be it.
Best wishes to you and yours for a good new year!

No problem Jon that's what we are here for. I have the BPD oil cooler as well as their bypass oil filter kit, 6 phase FICM and water pump. All amazing products and top notch quality and customer service. It's a pretty penny up front but makes the term reliability a reality for the 6.0l.
