Radiator hose - The 1947 - Present Chevrolet & GMC Truck Message Board Network

JCaldwell · 09-22-2009, 09:24 AM

I have the 72 with 2in body 454 and aluminum radiator and cant find a decent lower radiator hose for nothing everything either kinks (even with a spring in it) or just dont fit right..a 74 chevy hose bends are perfect but one side is 1.5 the other 1.75 I need 1.75 on both ends..any help?

No insult intended, but have you been trimming the hose to fit? They need to be cut down a little bit.

Have you tried the blue hoses? I cant remember but I think that they are goodyear??? I had a similar problem with my jeep and its lower hose, so I got the blue hose and have had it 2 years so far with no problems. I want to say goodyear gator hoses, but I dont think that is right.

edit* The hose is called high miler.
While I was looking for that I found this also.

Sounds like that might help also.

Yes I tried trimming them.. I have a flex hose now that worked great until I started it and it got hot then kinked and bent the spring in it

If you have a friendly parts store I always go in the back and find what I need. Bring the 74 hose and a tape measure to find one similar with the right ends. Or shove the 1.5 over the 1.75, I've done that in the past.

I ended up buying two different hoses cutting them roughly in the middle(it just happened that way) and using a piece chrome molly tubing inside to make the splice.
I used a Gates shrink to fit hose clamp which formed a nice clean seamless intersection.

Good idea...I would not have thought of that.

I had the same problem I bought the 75 bigblock lower hose the bends are perfect and I just lubed the hell out of it till I managed to get the other end on. On the other hand this thought came to mind "take the radiator in and get the lower part where the hose goes changed out and rewelded to the right size nothing a good welder couldn't or wouldn't do...

Where did you buy it if you don't mind me asking and did you have to trim anything off of it, are the bends perfect like the 74-75BB hoses? What application did you get it for Vehicle Yr/Motor....I would like to get my hands on a good fitting hose just in case...
Thanks Pablo.

Hey Petey I got it at the local Autozone I had to trim bout 3inches off the radiator end..no the bends arent the same as the 74 hose its actually a 70 K20 350sb hose but both ends are 1.75 and its really stiff it works perfect Ive been running the motor working the bugs out and havent had any trouble out of it.. The gates hose I had which was almost the same hose was actually sucking shut when I revd the motor up...Hope it works for you the only thing Petey my 72 has a 2in body lift so that helped me might hurt you..but defently get a Kelly Springfield no matter what you get..the guy at autozone said it was a goodyear brand
