ISX OIL COOLERS

[Tanker93]

Haha I wasn't gonna get into a screaming match over this even though everybody seems alright. All were really trying to do is turn these engines back into gen 2's. Good power, decent fuel and great reliability. Exactly what you need when pulling anywhere from 100-171 ton over long rough and sometimes steep terrain miles and miles from repair shops let alone your own workshop.
In our early days of these engines we once got a bill from cummins for $12,000 for a turbo change they had to go out and do on the side of the road for us. It was instances like this that made it obvious something had to change. I've been aware of this forum and the whole vgt vs fixed turbo for a good year or two now but like I said, it's too hard to find the right person to do the tune.
The guy that currently puts the tunes in actually connects his laptop to the truck while (via internet connection) another guy in the eastern states changes the file. Have been trying to get the name and number of this mysterious computer guy just so I can discuss what he's exactly doing and to find out exactly what he knows. The first guy I had come and do a tune (2013) admitted to me while he was doing it that he wouldn't know one end of a spanner from the other! alarm bells should've gone off then but being that we were desperate for an easy fix to our problems we still went through with it. Luckily that engine didnt blow but inevitably the turbo went eventually..
So now that most of the trucks have been converted and seem to be fine, I still can't sleep right at night wondering if there's something not right and they're all just timebombs waiting to blow. And I'm not gonna sit around and ignore the issue until things start going wrong.

When I can get a print out of what's in them, I'll be sure to message a couple of you for your opinions and even post results somewhere in this forum for all to learn from.
Thanks for your replys fellas!

Ps - changed a oil thermostat in one of them today. When I went to get the new one it read 215 deg far on it (old one was a 235 deg far)
