Technical Lower hose ideas

Looking for a 1 3/4" lower hose for the tempest engine swap, 2 tight 90s with a 45 degree downturn. I pieced one together and can hopefully snoop around oriellys tomorrow. You guys have any suggestions for an application?

 

Years ago I purchased 2 flexible heater hoses for a VW bug, they come in handy to use as a template for getting the shape of the upper & lower radiator hoses for a V8 or 6 cylinder,they will hold their shape while you are looking for the correct hose at the parts house. HRP

 

Lots of pictures with dimensions in this catalogue: dayco radiator hose catalogue pdf

If you get stuck...1 3/4 copper 90 degree and 45 degree elbows will get it done

 

You're on the right track..... If you've got it, you just have to search the racks. Hopefully they let you hunt.....

 

It would be easy if the aftermarket radiator didn't have a weird angle on the lower outlet...I could chop it off and weld it on straight but I'm trying to avoid that. I was just hoping one of you guys would have a lightbulb go off say Hey Lumpy that looks like a " insert make and model here" lower hose. Here's a tip for an 1 1/2 " upper hose... 1970-72 Monte Carlo, it's about 8 feet long and has several bends. Theres a section in there for everyone

 

You could take a small section of exhaust tube that fits inside of the hose, some clamps, and use what you already have.

 

Take a small piece of SS exhaust pipe that fits the i.d. and put at least 4 tack welds around the perimeter of each side. 2 hose clamps and you're done.

 

Silicone 90’s and 45’s with stainless steel couplers https://www.siliconeintakes.com/holset-turbocharger/

 

but I'd weld a small bead on the pipe so the hose stays on with the clamps.
done this many times.

 

Those are all viable...And yes I've done it in a pinch before. Hopefully tomorrow I will find a hose I can use. I'm trying to make it as clean as possible.

 

That link I provided has small length stainless tube available with stainless 45’s and 90’s as well

 

I tried with my '41. I used a Gates catalog online and Google for images, I couldn't find one but I did find a way to make it work. It did take some ass time behind the computer though.

Here's the Dayco catalog:

I tried... It would be nice If I could break it down to just 1 3/4" hose ID sizes....

 

It's a total time sucking pain in the ass. So you need 1.75 both ends, how long is the hose?.


Try this one:

 

The most important is the 4" between the 2 90s

 

They really don't get the accurate. You get the end IDs and total length, the curves you have to guess by the pics.....that's where Google images and a parts store come in.

Look at:
20621
22541
23721

 

I looked at those #s the bends are too far apart. I appreciate the help. Tomorrow I will search the parts store.

 

Sometimes it just doesn't work out nicely. I've used a piece of 304 stainless tube to clear a belt (used S.S welding rod as the clamp bead), I used a chunk of 6061 to join hoses on my '41 to get the tight curve I needed. Both didn't look factory, but worked.


Good luck.

 

Disdained as street-roddy by traditional hot rodders, but you're not running a flat-head Deuce. This stuff will fix you up in 15 minutes and get you outside to play in the sunshine.

^^^^^ No No No!

 

So, cobbled together bits and pieces of stainless, copper and silicon tubing with a myriad of hose clamps are okay but smoothly contoured curves of corrugated tubing are not? Didn't understand that in 2005,still don't.

 

I’ll repeat, “No No No!”

 

Phil P beat me to it. https://www.daycoaftermarket.com/wp-content/downloads/HOSE_-_2019_GUIDE.pdf Your scroll finger will get tired before it is over.

 

OK,why? Dayco makes a rubber corrugated hose, so does Continental. So is it the material or the structure? Both have been around for a long time. Cook-flex is all copper, made in the US and has a lifetime guarantee.

 

You can always change the inlet location……

 

I like the flex duct idea, but you gotta be gentle with it until you find a good candidate. I keep a few lengths of 1/2" aluminum tubing around for this. Bend to fit the space, write the end dimensions on the ends, and head to the O'reilly or NAPA. Both places have allowed me do it enough times that they just let me rummage through the back without all the dumb questions. Gotta admit, last time, it seems the inventory of usable diameters is way down. Modern stocked hoses are smaller in diameter. And funkier shapes.

 

I just Googled " One Off Radiator Hose Manufacturers " and there are companies over here that make one off's to your specifications., would not think that they are cheap though. Would have thought there were such places in the USA.

 

You could also use one of those shrink wrap style black "clamps" and it would be unnoticeable.

I used this on mine, painted it black
