Got hose? Ls swap lower rad hose - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Daaaanz67 · 08-29-2012, 11:56 PM

Hi everyone just completed my ls swap on

my 69c10. I'm using the stock three core radiator. It has the neck that comes off and angles up at a 45degrees just like the four cores I compared it to. The aluminum adapter is by jags that run. This hose fit like a glove. I also think that since these hoses have enough strait sections after the bends that even if your motor was set back towards the fire wall it will still work.I just wanted to give back to the swappers community as they have provided me with great information. I know there are many options on what people have used, this is what I did. I was lucky to have free rein in the napa/riebies rad hose section and this is what I used. In the first picture I used the adapter on the right

if you carefully measure and cut these hoses the left over pieces are enough for a second.

used this protective cover to clean everything up this came on the hoses I purchased.

So is that the one I need to order for the steam pipe in the upper hose?

Daaaanz67 · 01-25-2013, 07:23 PM

Yes if you choose that route. I just tapped the top of water pump and ran the hose to that.

i used a 1" galvanized pipe with a brass nipple, and spliced the upper radiator hose, works great and is hidden nicely under the the cold air intake..

The upper some people are modifying a 02 silverado upper hose with jtr fittings or man handling the hose to fit on the upper radiator outlet. Another option is what 19seventeecustom is doing
