LS3 radiator hose clamps and heater hose bypass?
 

Just wondering what you are using for upper and lower radiator hose clamps....something nicer than a regular worm-drive clamp! Also, I won't be running a heater. does anyone make a curved by-pass hose that is a different size on each end for the LS3?

Hose clamps
 

X2 That's all I use and have never had an issue with leakins

....I meant "?" not "!"....oops. How do you choose the clamp size? Let's say that the installed hose has an outside diameter of 2". Do you choose a clamp that is 2-1.75 or 2.25-2?

The smallest one you can get to slide over the hose with it installed.

I used the factory style clamps that came on my LS they look better than worm clams

If I remember correctly, someone said that if you pull out the hose bungs in the waterpump, the holes that are left are the tap drill sizes for 1/2 NPT and 3/4 NPT. Then they installed allen head plugs in the holes. It looked really clean. You will have to search to find out for sure.

I thought that if the outlets were simply capped off there would be an air pocket trapped behind them?

I did this for NPT to AN adapters for my heater hoses, could just as easily put a pipe plug in there. No drilling needed, just patience with a pipe thread tap.

3/8" and 1/2" NPT. The holes are the right size, just run a tap through.

I believe they make them for Afco as mentioned earlier

I was just watching You Tube tonight, Hot Rod Garage and they said never block the heater out lets it was big trouble, you should loop it if your not going to use it. I don't know I've never had an LS but figured I'd mention it. Anybody know for sure either way?

What is the logic behind that statement?


Presently every aftermarket AC system has a solenoid valve that closes of the water to the heater core when heater is turned off.

I think some believe that if the heater hose outlets are blocked off it won't allow all the air to be purged out of the cooling system when filling for thte first time. Thanks for the hose part numbers!
