Message: [QUOTE="Daddy454, post: 1409054, member: 25709"] [b]Even HOTTER![/b] So I'm dealing with this issue as well,only IMO-worse.Pulling my 6600# bumper pull trailer up Silver Zone Pass,to an elevation of 5940 ft.,not sure the grade- my EOT topped out at 262*.Ive done a bit of reading here on the forum,and this seems HOT,real hot.Ive taken this in to a fairly knowledgeable local indy,and they ran the laptop for codes-none,checked the cooling specs on the coolant-was good per Ford specs.Test ran it with the trailer attached,and said the coolant to oil temp was about 25* difference?I left the shop,and ran it up another short summit nearby,and got it to 255* by the top.Runs around 215-218* just around town. I've read some threads about oil cooler issues on these pigs,as well as the freeze plug in the upper pan issue.Indy called a dealer in SLC,and they said as long as its not at 250 sustained around town,it should be fine.Also said "lift/big tires",could be the culprit.I'm not so sure. I checked the input and output temps with my temp gun when I got home,and the difference was only 7*...215 in,208 out.Any ideas?Totally stock as far as I can tell. [/QUOTE]
