Additional methods to keep the EOT's down.

Looking for some info on EOT and ways to help the EOT stay low.

I have a 2001 Ford F350 7.3 CC 4x4 auto 263k

The EOT will climb under load and will get to a range that will damage the oil and motor. I'm thinking since I'm pulling up a long climb and the EGT's are high due to how much I have to stay in the pedal, its causing the motor to get hot and raise the EOT.

The ECT gauge on the truck doesn't move until the EOT get really high. It will then start to over heat. At that time I pull over and let the truck cool while running.

If the truck doesn't have a programmer on it and is stock, the EOT will usually not go above 220 while unload load. Of course, I don't get any of the power needed when at stock.

Are there any kits out there that I can have installed for an additional method to cool the oil?

What tunes are you running?

If your EOT is getting hot, your tranny temp likely is as well. The tranny gauge on the dash is just as bad as the ECT gauge. It doesn't look hot until stuff is cooking. 6.0 tranny cooler will help your tranny.

Your oil is cooled by your coolant, and it is possible that your oil cooler is simply clogged nasty. Have some chemicals flushed through your oil and coolant systems, then install a new cooler.

Thanks for the advice.

But I'm still looking for something that will also assist in the cooling of the oil.

Is there a external oil cooler? Any recommendations?

How hot is the EOT actually getting? It has to be super high to actually damage oil...

You must have something wrong, plugged radiator, messed up thermostat, or the clutch on the engine fan... or your oil cooler isn't working properly....

That's what I'm saying. Your stock unit shouldn't have an issue keeping up. Whatever tuning your running could be a player, which is why I asked about it. Aside from that, it would seem that something is actually wrong with your current system. That's why I suggested a chem flush and new cooler. Adding another system onto a broken one won't fix the problem, just mask the symptoms.

Tuning isn't going to affect his oil temp. If it did it would be a small change. Heck the sensor is like a +-10 degrees.

Thank you everyone for your assistance. Turns out quite a few of you were correct. The stock oil cooler should be able to cool the oil. I heard a noise coming from the belt tensioner, so I changed the belt and tensioner. That did the trick. I would like to see the fan kick in at a lower temp, but I can't seem to find anyone that has specs on their fan clutch.
