So I called Kenworth and asked the parts guy how I could tell which one I need and he says "you gotta measure it!!"
So, I said well...I'd kinda like to know which one before I start tearing anything down....just in case they're backordered for months.
He says "yeah I suppose that makes sense...but you'll have to call back when other guys are in. They might know how to figure it out"
Figured I'd come on here and see if there's a way to know WITHOUT tearing apart the engine?
Thanks

Is this your first ISX rebuild? There are A LOT of things that you will need to know that aren't in the manual so I would advise you do your homework if you want the rebuild to last.

Answering your question: there is absolutely no way to know which liners you have until you pull them. Second, there is are ZERO aftermarket kits you should buy. You might as well not rebuild it unless you're going OEM only AND you are installing a brand new head (no reman, no rebuild). Third, you need to have someone cut counterbores properly and shim them to 15 thousandths. There's a lot more but Im trying not to write a book here. Good luck with your build!

No I had an out of frame done on this engine. It lasted just over half million miles so far...all at heavy weight (150k pounds). But it just started pushing antifreeze the other day so I'm preparing for the worst case scenario.
It might just be the head and gasket...not sure yet. I did hook up a hose to the cap on the overflow side of coolant tank and eventually started bubbling.
Oil pressure was good but oil temps and coolant temps were a little higher than usual a few days before it started. The fan was coming on more often because the coolant would climb up pretty quick. No white smoke or anything.
It's in the shop now to get looked at. He was just checking the simple things like compressor first before the head comes off.
