Changing radiator hoses

[turbo_bu]

2004 LB7 with ~100k on it. Truck gets used occasionally as tow rig for camper / car hauler. No real issues, but am starting to wonder about IF I need to change out the radiator hoses when I do the coolant again. FWIW - they look OK, but obviously, they will start leaking from the inside. Wondering if I should go ahead and change them, or have guys had good luck with them lasting to say 150k? 200k?

I started looking at the cost and obviously the lower one is expensive. Tried Rockauto, and now as usual has me more confused as to which part # I really need.

Rock shows for the lower hose:
ACDELCO 26397X {#88920368} - for $46!

also shows
ACDELCO 15792831 GM Original Equipment - for $132 .... hmm that seems more like it, but what the heck is that 1st one listed???

Similar confusion for the upper hose:
ACDELCO 24485L {#88920262} Professional; - $10

ACDELCO 15792832 GM Original Equipment - $72 ... but that hose includes the clamps

One last question is for the other coolant hoses, like the heater core line with the quick connects on it. Are you guys replacing those too?

if they feel fairly stiff, i wouldnt worry too much about them. seen guys go 200k and 15 years on stock ones.

i would look into replacing the little rubber hose behind the fan pully, the hose next to the turbo on the passenger side (not the heat hoses) and possibly the long hose coming out of the turbo to the upper steel rad hose. those get missed all the time and are the firsts to go.

I'd e more worried about the fuel lines in the engine then the radiator hoses at that mileage.

Are you talking about the fuel hoses that connect from the frame to the engine? or are there others fuel lines you are referring too?

mostly the ones that run from the filter to the CP3, then the return lines from the CP3. Basically all the fuel hoses in the valley of the engine. they tend to get heat stressed, rot, dry out, split and collapse. a source for all sorts of problems.

To help you resolve the questions about correct parts numbers for YOUR truck, get your VIN# and go to a GM based parts site, such as GMPARTSSTORE.COM or GMPARTSDIRECT.COM and input your vin#, then start looking for your part. Once you know what GM thinks is the correct part number, you can start your shopping for price, delivery, etc.

The price difference with the ACDelco parts is because ACDelco makes several types of parts. Their "Original Equipment" parts are the OEM parts. This is what you want if you want the original part. Their "Professional" is equivelant to walking in to a parts store and getting their cheapest garbage part. I have incredibly bad luck with ACDelco Professional parts. IMO they are worse than Duralast, and often more money.
