Factory GM Serpentine Setup Help

[Snowbound]

Gents,

I mounted a serpentine set up with AC delete to my '65. I'm a little lost as to what upper hose to use. The factory 65 hose interferes with the alternator.

I'm running the stock HD radiator with 1.75" inlet/outlet.

I'm hoping to not have to use a flexy hose! Any help?

I am running the GM serpentine setup as well. It is a great system! Very well engineered and light-years ahead of the old V-belt systems. I really like it. I too had interference issues with the upper rad. hose. What I did was go down to the parts store and dig through the various hoses they have hanging on the racks. I found one that was the right diameter and had bends that seemed like would fit. Bought it, lined it up, cut it, and bolted it right in.

Don't suppose you have the number off it? Nobody has much stock of anything here.

I'm all ears on this one. I'm using a serpentine system from a 1990 half-ton truck. I was planning on bending up a tube like the V-8 trucks had and using the small 4" hose sections on each end.

Thought about going to your local muffler shop and having them bend you a piece of alumanized exhaust material?

This is what I did. It is a BB but pretty much the same. I had to get a thermostat housing from a van which pointed straight up and I also needed it to be threaded so I could put a return line for the heater on it.

What I did on mine is I went to the local parts store and went through all the (gates) flex hoses and found the correct length (upper and lower hoses)...sorry cant find the part #s... I ordered a chevy 45 degree rotating water neck thermostat housing swivel style on ebay (Whites Performance) with shipping under $15.00..here sum pics...

we took a coat hanger and bent it to the correct shape, noted the diameters, then went to the parts store and went to the back wall and found the hose we needed. Took about 30 minutes...

please post part# if you have them---

The stat housing from the 91-93 Roadmaster/Caprice might help. It points backwards to clear the hose around the accessories.

Are you using the old alternator on the newer mounting brackets? Depending on which wiring harness - OEM or newer (upgrade) you are using here is a helpful link. I went with newer alt and a new aftermarket harness from AAW. Hope this helps... http://www.americanautowire.com/PDFL...20IN%204.0.pdf
