Looks like your right on track, T.J. Everything sounds right. You do need washers for the adapters at the cooler.

Like Rotortuner said, it would be a hell of a lot easier to go with the pre-fab ss lines (for a FC), if they fit.

Or, if you already have the stock lines, it may be cheaper to buy a small radiator, and turn around and sell yours.

 

Im not trying to make my own, I just want to tell them what I want made...Which is a SS line X inches long, with a -10 female fitting on both ends, and another SS line X inches long with a -10 female fitting on both ends. Then, I can buy the adapters from somewhere, and the 90 degree fittings from somewhere. Then, just put it all together and Im done .

So my parts list should include:

(3) 16mm/-10AN adapters
(1) 18mm/-10AN adapter
(3) 16mm sealing washers
(1) 18mm sealing washer
(2) -10AN 90 degree elbows (female on one side, male on the other)
(2) Custom length lines with female -10AN fittings on each end

Ok, new thought...I could just have 90 degree fittings put on the two ends, that way I wouldnt have to buy 90 degree fittings seperatly..


So now I just need the adapters, the washers, and the hoses made. Im good to go, I understand it now .

~T.J.

 

Ok TJ. As was said, you ask for an "AN dash Ten". The dash indicates dia. in sixteenths of an inch. So -10 is 10/16 or 5/8. ( Hoses are measured in ID and tubing in OD). ABsolutely have the hoses made with the elbow fittings. The metric-AN adapters are male unions, which means you'll have a male end on the engine/cooler. The hoses will be female B-nuts. A 90* adapter that is fem on one end and male on the other is next to impossible to find. I didnt like the Mazdartix lines for one reason, one of them (I forget which) doesnt have an elbow, its just a straight fitting and the bend is done by the hose. In avaition thats a BIG . It puts extra stress on the hose as it's always under a bending load, especially when you gun the engine and it twists in the mounts. I ended up with a 90* in the rear and a 45* in the front,came out very nice. I can snap a pic and send it to you if you want, however on the cooler I have a 2nd gen one so that will be different. Personally, as an aircraft mechanic, making AN hoses is really pretty easy TJ. It just takes good common mechanical ability. I bought the parts from summit and it came out cheaper. The fittings come with instructions right out of the aircraft standards handbook. Follow them and you wont have a problem. WHen you need to cut an ss hose heres a tip. Wrap the hose with tape, draw your cut line, and then cut. Don't cut it like your sawing wood, you want to cut towards the center of the hose always. If you dont, as you saw through the lower half you'll bend the wires out and away from the hose as you cut. Thats what gives people trouble cause when they get done the have half the wires splayed out and away from the hose, and they are tough to bend back. Then when you try to put the collar on the hose, the wires want to stay sticking out. SO position the hose, cut through the hose, then rotate the hose and cut towards the center, continue till you have cut all the way around. A hacksaw works fine, so does a cutoff wheel, but that has a tendancy to smoke the rubber and make it stinky LOL.

 

TJ, think for a minute. How do you know whats in that cooler? It could have metal in it......... Remove the plug and clean the t-stat and flush the inside of the cooler good,real, real ,real good. Oh and good thinking to pressure ck the cooler. DOnt forget to do the same with your hoses, whether premade or not. ANd be careful installing the big plug and the fittings on the cooler. The tanks are soft aluminum and if you overtighten them you'll cause a crack in the boss.


Oh, you can try purple cleaner (like castrol super clean), or NAPA sells a spray bottle of aluminum brightener, that might get your paint off.

 

I understand what you mean about the hose making the curve. Ive seen those hoses, and I think its silly.The only real question I have left is if the 90* fittings that Im gonna have put on have a swivel thingy, lol. I mean, like a garden hose how you can tighten the fitting without turning the whole hose. Basically, can I put the hose facing the direction I want, and then tighten down the fitting? I assume I can...Otherwise it would just be stupid cause you would have to get the exact number of threads to make it face the right way, lol.

Anyway, I plan on going to a shop or two tomorrow (if any are open) and trying to see if they can give me a price to have the hoses made. Im also gonna try and make mounts and mount the cooler tomorrow so I can get an idea of how long of hoses I need. This project is definatly gonna drag on as I have no money to have the hoses made, lol.
Also, Rx7Carl...How do you make your own? Do you have to crimp them or what? Im not to clear on that aspect of it. I was thinking of trying to make my own, but I dont know how they work...

Anyway, thanks for all the help .

 

Will do, thanks .

~T.J.

 

Don't worry about the swivel, it's like the end of a garden hose where is screws into the spigot. Also the nice ones summit sells can even be swiveled after it's tightened! Way cool!

A cheap alternative if you have no $$$$. Cut off the crimped sleeve from the stock hoses, then remove the hoses. IIRC the stock fittings are barbed, so you can but some apporipriate hose, and use a couple of hose clamps to secure it. The you only have to buy some hose and clamps for now.

No, they are not crimped, that makes the ends re-useable. If the hose ever fails, you can disassemble it and put in new hose. The red part (sleeve) screws onto the hose. Then the elbow screws into the sleeve.

 

Question on AN type fittings.

What are they? Are they like a flare nut type connection or are they like a quick disconnect like on shop air tools? How do they work? What is their advantage over other types of connectors?

 

Come again, eh? Pictures?

~T.J.

 

Neither. A pic is worth 1000 words. If you really must know, gimme your email addy and I'll send you pics.

 

u too TJ I'll snap pics and email them.

 

i want pics

 

Along the same lines..

Cheap SS lines.


How to make your own lines

 

Got any pics of the line that comes out of the engine on the driver side? Did 79-82 cars have a line that came straight out or did it make a bend? The reason I ask is because if it just comes straight out I could just cut the T off and use a 82 heater hose sinse it would fit perfectly.

 

God, u guys are gonna make me....... Ok, another tutorial, hows that sound? The AN mystery .... solved at last. Or something like that. I work with it everyday,for the last 20 years or so, so to me and the guys at work it's old hat, but maybe something you guys need to know. Or at least know what your talking about.

 

It is a T fitting, but if you cut the entire T off, you still have enough room to stick the hose back on. I did it that way.

 

Sure, why not.

 

Well, I figured out what you meant, Rx7Carl. I cut the crimp part of the connector off the hoses, and kept the barbed fitting that goes inside it. So now, I plan on getting two lengths of SS line (or even just oil/heat resistant rubber hose), and then putting a couple screw clamps on each end of the barbed fittings. So then, afte I save up some more money, I can get the AN fittings on there.

One more question about the AN fittings...Are you saying that they are just screw together type things? Or do you have to crimp anything? If you could send pictures to tjay31584@hotmail.com , that would be great. Thanks.

~T.J.

PS - I know I dont need that adapter looking thing thats sitting up there, its just what was attached to the line that went to the front cover cause when I took the cooler off at the yard. That came undone rather than the line from the adapter. Oh well

 

Wait...I think I got it...You have the outter "collar" (red) that goes on the hose first, and the you have a barbed fitting (blue)that goes inside the hose just like the stock ones. Then the red screws down tight to the blue piece which crushes it all together? Is that right? If thats right, Im making my own lines .

~T.J.

 

Should be on the forum... Check my profile.

 

You got it. Use some Anti-sieze as well.

 

Are you talking to me? Use the anti sieze between the blue and red pieces?

~T.J.

 

You shouldn't need that adapter piece, unless yours just comes out of the front cover. They seem to like to do that.

 

Yeah, thats what I was saying. Thats how it came apart on the yard car, lol. Im going with -AN fittings so mine has to come out of the front cover anyway so I can put the adapters in .

~T.J.

PS - Once again, I learned something new here. Thanks guys .
