Hi everyone, it seems that my heater hoses are leaking right above the passenger side frame rail on my trailblazer ext. So I figure it's time to replace them. When I went to look up the part numbers on the diagrams, it seems that since they are no longer available the part numbers are not labeled anymore. I went to rock auto and they have a whole bunch of heater hoses listed with their applicable part numbers. Looking at the attached diagram the hoses that are leaking are #9 and 19. I was gonna replace 21 while I had everything apart as well. I have tried researching these part numbers before asking on here, so if anyone can please let me know the part numbers I would really appreciate this. Thanks
