New oil cooler, oil temps high.

I just finished putting a cam, headstuds,EGR delete, and oil cooler in an 07. I took it for a ride tonight and the oil temps were at 225 and the coolant temp was around 185. I had this engine tore all the way down and before I put it together I flushed it out with a garden hose. I also flushed the radiator. What gives? I can't imagine the cooler is plugged already, it only has about 20 miles on it. Any ideas?

before you tore everything down did you run vc 9 and all the flushing agents?

there have been alot of ppl getting new oil coolers clogged because they did run the anti iron and anti silicate agent before they installed new parts etc...

The truck was brought to me partially tore apart so I couldn't, that is why I flushed it with the hose. I was hoping to get mosy of the junk out by flushing, maybe it didn't work.

ya the vc-9 is what gets all the gunk out i think it might be clogged again. there is a way to reverse flush the oil cooler there are some threads on here. other more experienced members will chime in soon.

google the reverse oil cooler flush would be best try its easy and only 2 bolts without tearing anything down.

I let the truck sit today without starting it, checked oil and coolant temps while it was cold. Oil temp was 50 and coolant was 30. It was around 30 here all day, kind of thinking maybe a bad sensor.

Your sensor is faulty. Replace the sensor and try again. But even at that if your sensor is off 20 at ambient temps and your oil was 225 that still means your oil would have been really closer to 205 so you may not be out of the woods yet, but definitely change out the sensor.

Sorry to bring this thread back, but did you ever find out your problem? I have a similar issue, and suspect a faulty EOT sensor.
