SR heater hose

IB :repost:

Ok, so I searched forums seen several sites blah blah, and they tell me
what I need to do to re-route the heater hose on the SR block to hook
up to the ports on the firewall.

I also gather the SR hoses are slightly larger then the KA hoses/ports.

One of my hose is also ripped/cracked (the one that sort of makes a U-
shape when you flip it over).

Varun said he has part # and shit but I told him I’d find it myself. Well
I’m an idiot because I don’t know what to get really.

So yea, someone who’s done this wanna tell me what hoses I need
specifically? Length, shape, I.D./O.D. and/or part # from Canadian Tire?

I saw the parts on HeavyThrottle’s site but can’t tell what dimensions they are.

I just used all the hoses etc from my KA and it was simple

I do have the part #s for the SR hoses which I believe are gates #s so I will post them up shortly…

I will try to get pictures of mine today as well to give an idea of how I used the stock hoses and routed everything

3

Yeap Gates #. Someone mentioned those to me but didn’t give me any #s.

Thanks mate

4

okay… there are 3 hoses ? I think you may only need two ?

#s are… 19666, 19606 and 28467

I have no clue what which one looks like or what not but I got these #s from Varun months ago… They are the same on Zilvia and 240sxforums as well

:bowdown:

This is all I need. I think varun was trying to give me these same #s but
me pretending to be a know-it-all said “I’ll find it myself”. :rofl:

So will CT have these or do I have to go to Napa or something?

6

Try Napa… I’d call first and run the #s past them just incase their not in stock but they may be able to match it in the system to another item which is in stock ?

I usually phone before I go out looking so I dont waste my time.

7

Yeap, I phone ahead too.

Thanks a lot dude, really appreciate it.

From NAPA:

#19666: $27.99
$19606: $15.29
$28467: $17.01

+tax = $69.33 Total :noes:

I checked CT; they didn’t have it.

Any cheaper alternative? I put an order for it (but its returnable).

on both our SR swaps we used hoses from the KA along with some ‘reducer’ pipe fittings found in the plumbing section at Home Depot. not that hard really… just take the two hose sizes with you and find a piece that’ll join them.

the pieces we used are grey plastic.

10

talk to cal, he’s running a neon upper rad hose and its perfect, he has part #, lower KA hose should be okay.

11

Well this is for the heater hose that’s behind the cam cover.
I’m not concerned about the upper-rad hose just yet.

The u-shaped hose (the one that most flip) is busted in mine
and so I can’t use it. That’s the one that cost $28

I know the size of hose and all that junk; it’s just I don’t know how
long and stuff I need it.

I can always return these hoses to Napa (it’s near my work) if I can
find an alternative at a lesser cost.

12

ah-ha. is the engine in car? if not its easiest to remove a metal bracket on the rear of the valve head that holds the hoses in JDM locations.

Once bracket is removed, it easy enough to use the bulk heater hose (from princess/napa/CT) and copper elbows $.99, to avoid kinks, and re-route the lines

13

Motor is still on the floor and I’ve looked at several sites that show you
what needs to be done.

Only thing I don’t know as I said was how much hose (lengths) I need.

I will take some pics tonight of the hose that I get from Napa.

Basically it’s all prepared in the back for the rerouting (brackts removed
as necessary). Just the two large hoses needs to be hooked up.

14

how much hose? I bought a 10’ length from CT, @$6? it was wraped into a circle but was straight bulk hose, and then used a couple 90 degree copper elbows and hose clamps,

bada-bing

15

By anychance have pics of it?

I’m like the biggest n00b with this whole hose business; I should have it
done already but meh :o

I just wasn’t sure of how long I needed to make the pieces to make it all work.

BTW, Do you remember the I/D of the hose from CT?

16

no but just take a 1" sample of the hoses you need, use the sample to find the correct size and be assured that the copper elbows work.

I personnally would reccommed adding a rad flush fitting in there, it’ll help when it comes time to bleed the system. this fitting looks like a T with the top centre having a screw cap that can be connect to a garden hose.

17

Gotcha. Thanks for the info.

Man where do you work. You seem to be responding quick. :rofl:

I just check my email for notifications every few min hence my fast
replies. I’m gonna get fired. :noes:

18

I will try to get you a picture of my setup Gonad

I used all the heater core lines from my KA… there is 1 that is bent all funny “hard to explain” but with a tiny modification she fits on perfect

Lenghts arent to much of a issue… I’d say 10’’ max and 4-6’’ for the other ? One is pretty much just a 90 coming outta the fire wall and the other is routed behind the motor somewhat…

Will post pictures tonight

classified info, need to know basis 8)

The heater hose sizes needed are 3/4 and 5/8.
Those “grey” reducers from home depot aren’t meant for the temps the coolant will reach and they will melt… trust me :oops:
And as for the rad flush fitting… if you need it for a rad flush sure its a good idea… but for bleeding the air out of the system there is already a bleeder screw on the coolant inlet on the block . (10 mm bolt)
