I hope it's ok to post in this section since my truck is the "old style" body.



I have a 2007 Classic and I'm doing the coolant flush and want to replace all the original coolant hoses. I found the lower and upper radiator hoses at the local parts store but I'm having trouble with the heater core and coolant tank hoses.



I found these numbers on the hoses:


Heater Hose, from firewall to engine block:15763388
Heater Hose, from firewall to junction where it intercepts the hose from the coolant tank to engine block: 15792821
Radiator to connector under throttle body (small dia. hose): 15274729
Radiator to coolant tank: 15170551


If anyone could point me to a site with photos and numbers I'm sure I could figure it out.

Thank You so much,
