Gents, I searched and couldn't find anything related to this so hopefully not doubling up.

Truck still has the factory hoses on the cooling system and I'm starting to have issues with the lower radiator hose leaking at the radiator, so I figured hoses are 15-years old might as well replace everything.

I generally try to go OEM and see that I can get most of the hoses thru Riffraff.

-Upper/lower radiator hoses
-(2) Vent hoses that go to the Degas bottle
-Hose from the bottom of the degas to the Water Pump with a new wye fitting

I'm not finding some of the hoses however. I've tried looking thru Autonation's parts fiche which seems to be much less user friendly that it used to be. Any suggestions where I could find these hoses? I would still need the following:
-Water pump to Heater Valve
-Heater valve to Heater Core Inlet
-Heater Core Outlet to rear engine tube
-Rear engine tube to Degas bottle wye

I see Rock Auto offers some after market hoses for significant price savings but I've had issues in that past on other vehicles with these not fitting correctly or not lasting. Would prefer to stay OEM unless someone has a different recommendation.

I might change the degas bottle as well. It appears to be original as well but it not currently leaking.

 

I see Jack recommend Ford Parts Giant for at least finding the correct part numbers. They are not a Ford dealer, but armed with the right numbers you can go shopping.

 

I say the same, check on tascaparts.com or fordpartsgiant.com
Ah man, i removed and cleaned all the hoses you listed and all say the Part Number

 

For this, RockAuto is the best search. The heater hoses for the vacuum valve come with the valve as a unit. It shows the Ford part numbers so you can plug them into a Ford site.

ANWB and Tasca both use the Ford.com system.

 

THIS!! There are sites trying to charge you $50 to answer these questions, and they aren't as good as the guys here helping us for free. I try, Lord knows I try, to buy these guys beer, dinners, give away parts, my meager help, whatever. Just no way to repay.

 

Awesome thank you guys! Didn't think to look under the HVAC section for the heater hoses. I was going to replace the heater valve anyways as it's started to seep coolant from the body.

Interesting find on pricing, I spot check the heater hose/valve assembly (5C3Z18472F)
Rock Auto: $77.79
parts.autonationfordwhitebearlake.com: $78.19
Fordparts.com with ANWB as dealer: $102.60

The two ford sites list the same MSRP, just with different discounts.

I would almost just use Rock Auto as their website is so user friendly and they appear to be selling genuine motorcraft stuff.

 

The other thing about RockAuto is you can google for a 5% discount coupon code, but also check the shipping costs of each source.

Lakeland Ford is also a good source.

 

This is what I have (primarily just in case others stumble across this thread):

03-07 Heater hose: WATER HEATER HOSE supply line (inlet) to Heater core from water pump tube: w/ High Ambient Temp & Speed Package. With heater valve: 5C3Z-18472-F (KH439)

03-07 : WATER HEATER HOSE return line (outlet) from Heater core to tee in hose under the degas bottle: 3C3Z-18472-BB (KH611)

DEGAS TANK HOSE (Bottom hose) (05-07): 5C3Z-8075-CB (KM4858)
