Is this radiator hose correct? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Am replacing the old/generic hoses with new (hopefully) stock ones.

Working on a '69 GMC, inline 6 (230/250).

Can anyone confirm this lower hose is correct?

RockAuto lists a Gates 20489 as a lower hose that will work on a 69 GMC C15 with a 250 but does not show it for a 230 but it appears to be close to the same size so it might work on a 230.

Thanks. I find that a lot of places will list the 250 but not list the 230 at all. Odd.

I'll give this one a shot this weekend and see how it fits, unless anyone else chimes in.

You'd think the physical (outside) of the 2 engines would be the same, at least that's what I've found in my research. Meaning what works on one, should work on the other, for the most part.

The diameters are the same. The hose shown for the 230 is a little longer and is a flex hose. They use the same water pump so it seems like the routing of the lower hose would be similar.

I noticed that. Still, you'd think the hose would be the exact same between the 230 and the 250, but I'm far from an expert.

I may end up just having to run flex hose for now until I can figure out if there is supposed to be a difference for the 230.
