Drop in molded heater hoses for FD - Part Numbers Included
« on: June 07, 2012, 01:49:02 PM »
Posed the question a couple of weeks back and it didn't seem like anyone has gone through the trouble to find molded heater hoses that fit the LS1 in a FD chassis better than a straight hose that bends way up on the fender liner. Well, after several trips to my local auto stores I have the solution.



Gates 18078
Gates 28471


and for our Canadian brothers here is a set of alternative part numbers found by quinns in reply #47:

Dayco 87611
Dayco 80405


I haven't verified the above part numbers, but I expect quinns has tried them.

The picture above doesn't actually show both of the correct hoses. I later found that 18078 was a better fit since it is a 5/8" hose that scales up to 3/4" right at the water pump nozzle. Gates 28471 is 5/8" all the way though. I've found that 5/8" is a good tight fit on the heater core barbs (may require boiling the hoses + windex) and my LS1 water pump uses a 3/4" and a 5/8" barb, thus the need for one hose to transition to 3/4"

They aren't truly "drop in" like my title says as they will require a little shortening, but it's pretty dang close and when you're finished, the routing will look factory.

Thanks Lane! Good stuff.

Did you guys have to look through a lot of hoses to find these?

Yes, I remember you saying you'd used molded hoses but you were being a little butthole two weeks ago when you posted in my original thread and wouldn't give out the PNs ;)


Thanks Lane! Good stuff.

It wasn't too bad. The 5/8" hose that flaired to 3/4" was the worst since none of the stores local to me had exactly what I was looking for, but they had hoses that put me in the ballpark PN wise and I honed my search in using google.

I wasn't going to post pictures before I was completely done installing them, but someone asked so here's an intermediate shot.



When I took this picture I was using a full 3/4" hose for the bigger barb on the waterpump and then manually steped down the 5/8" further down the line. The part number I posted in the 1st post lists the hose that does the flair on its own.

Also. I was asked about heat concerns since the hoses pass close to the headers. My pic shows fiberglass sleaving I bought at mcmaster carr, but I've since decided against it since I think it's going to be a dirt magnet. I'm in the process of replacing the braided sleeving in my engine bay with DEI Fire Sleeving that has a iron oxide silicone rubber shell and should 'clean up' a little easier. If you want to do something similar, you'll need ~ 6ft of 1" ID fire sleeve:

damn man you think you got them clamps tight enough?  I would just use the factory spring clamps they dont cut into the nice hoses you just bought.

Haha! That picture makes it look worse than it is. I'm kind of gun shy when it comes to coolant leaks. I had a leak at the heater core connection that I misdiagnosed as a leaky core. One dash removal and installation later I'm warry of leaky coolant connections :D

I've always heard not to use them on fuel lines, but I never really dug to found out why. Good to know.
I didn't get any OEM clamps with the engine, but I'm pretty sure I can find some constant-tension clamps from mcmaster.

Thanks for the tip
