Another coolant question.

[coltsfanjmcguire]

I'm about 11k miles in on my current oil cooler (changed by a ford dealer) and I'm watching my deltas get to 12 resently so I'm preparing my self for another one this summer. I'm using premium gold (don't everyone rip me apart at once). Has anyone had issues with oil cooler after putting in ELC? I know you have to get all the gold out but is that really the end all fix for the oil cooler?

No it isn't. The end all fix for the oem oil cooler problem is a Bulletproof Diesel remote oil cooler that eliminates the oem cooler. Replacing the oil cooler, running a coolant filter, and using Rotella Ultra ELC is a good less expensive alternative but it is not 100% bullet proof.

He's 100% correct ELC doesn't fix anything but longer change intervals and running a little cooler, less to worry about from cavitation etc.

The problem is the crap casting sand, gelling from neglected gold coolant etc. running around inside the engine clogging the tiny vanes in the cooler itself.

OP you should really try a reverse chem flush and definitly a coolant filter.
