You mentioned putting my truck in my sig, but aren't all the 6.9 and 7.3 oil coolers the same?
Yes the oil coolers are the same. It's just nice to know, what truck your talking about for anything in the future, it's kind of like reading a book, you read to the end and it sticks in your mind. That info in the sig then is always included at the end of trouble post. If you don't want your sig to show, just uncheck the box "Show your signature"
