My SA claimed it was a part number change on the hoses for the 23-24MYs. He was seeing a lot more of those model years come in with coolant leak issues compared to 20-22MYs.

 

Yes. Part numbers are changed. I listed the new and old in an earlier post. The pipes are the same though. Probably means new o ring material on the pipes means all new part numbers.

I wonder if there is a new o-ring part number that my homework didn?t reveal.
