But from what I have gathered it doesn tmake any sort of difference AS LONG AS you STAY with that coolant when you might have to add a little ( for whatever reason???)

MY CAC has been repaired and should be re-instaled today (friday)

AND...the CC tech must have been wrong...'cause there wasnt any oil cooler attached to my CAC at all..???

Sully,
First off, that's what I was going to suggest was, go and get an estimate from a radiator repair shop to see what was entailed to fix yours, if it could be repaired that is, and, what the cost was. You see, in all my years as a fireman, we had several CACs repaired on our trucks. They get such harsh treatment in that environment. Many of them cracked alongside the collector boxes on both sides and, even some tubing in the field (center).

But the point is, they're all aluminum so, a good radiator shop can handle it. Now, again, in a zillion years of being around fire trucks, I've NEVER SEEN ANY OIL COOLER or, anything else that's heat related attached to them. I mean, WHY would anyone (manufacturer) do that, to increase the external and internal temp of that air cooler when it's soul purpose is to COOL THE AIR THAT'S BEING FLOWED THROUGH IT?????

And, as a side note, our '04 Itasca Horizon 36GD with the C-7 330HP CAT also uses the RED coolant.
