AN Line for lower radiator hose

Dave Steltz · 12-23-2007, 05:09 PM

I will be needing to change over to a braided line for the lower radiator hose this year...What size is "normal"...I think today the lower hose is 1 1/4...so what does that come out to in AN hose....

Easiest way to convert any AN number to inches or vise versa is to remember that the --(dash) number is the number of 1/16 of an inch in the AN size --So 1 1/4 inches is16 1/16 for 1 inch plus 4/16 for the next 1/4 for a total of 20/16 of an inch for 1 1/4 inch---You will need a --20 hose and fittings for your application---Understand???? Hope this helps---Comp 387

I would start by seeing what the largest size AN adapter the radiator will accept. If you are welding that fitting on/in, I would see what the largest size AN adapter the pump will accept. I think Bigger is Better.

You would you weirdo. Always knew that firemen were a different breed.

As far as the conversion goes...for a gas application I would run -12 or -16 (pricey)...for alcohol I would run -10 or -12. It depends on you vehicle. If you are in a digger...go with the smaller...in a door car with a closed nose you may need the extra coolant capacity and choose the bigger line. You have to be careful not to move the water too fast. You could always go bigger than run restictors to help slow the flow.

If you are starting from scratch it would make sense to put the biggest size in the first time. I have never heard any one complain about thier car cooling off too fast between rounds. You can always warm the car easier than you cool it.

If you try to "COP" out and save a few bucks, it may prove costly in the end.

Dave you can probably make things easier to hook up by turning the pump upside down. I struggled to get a lower hose connection on there with the Ron's pump directly in the way. I've seen cars with the pump installed upside down on a BB and now you have a much easier time getting that hose connection made.....My latest car was an alcohol burner and it has -12 fittings in the radiator. My old car had -12s and 1/14" hose and on alcohol it would run forever at 150 no matter how hot it was outside. On gas it was tough to keep cool with that same system. Johnny is starting to sound like the "Shell Answer Man". What is it with Fireman and Cops, they always want to fight.....Merry Christmas......

Rich as you might know I got the set-up off of the JOM's car, and of course nothing fit the way I wanted it to...So I bought a new waterpump (I was still running a stock one with a electric motor)..this one has outlet holes in it on both the right and left, so I can come out the drivers side and head back to the lower pass side with the hose...Since I have to buy fittings and line, I think I am going to run a -16, then into a hose adapter so I dont have to have a fiting welded into the radiator...

the car I just bought has -16 for rad. hose upper & lower.

Someone makes a threaded adapter from pump to regular radiator hose, I had one on one of my cars. A little research may even find a preformed hose that fits just right. that would save a bunch of $$$. Good luck

Merry Christmas
