Bypass hose splitting

Pics of hose. The other 2 slit in the same place.

Thanks for the tip, MOTOPSYCHO, I will swing by O'Reilly's this afternoon.


Could there be a restriction, as suggested by "66PLYVALIANT"?

Car does not run hot, and all seems to be normal until it splits, leaks ALL of the coolant, and then starts to get hot. Easy enough to replace, but a significant inconvenience!
