2003, 5.9 Overheats at 70mph
Ok, so I've noticed that if I stay below 70mph my truck will maintain a constant temperature of 200. If I get up to 70mph it will quickly heat up to 245 or bury itself into the red. When I slow back down to 65 the temp cools right back to 200 within a few minutes.
I have replaced the fan clutch. No luck.
What's next, any tips, anyone ever heard of such a thing? It's got me baffled..

Just got back from a little trip around the block, no bubbles visible at the radiator cap while at 200 degrees.
