Steering box fitting sizes???

I searched, I tried many different searches and read a lot of threads to no avail. One thread was on here where the guy added one of those tube coolers.

I did find a small amount of info about the style they are (inverted flare?) but not the size. Go figure.

I see pictures on rockauto of the end as well, and of course its the same style that go into the back of the PS pump.

So I guess now my question changes mid post.. Can I just use an inverted flare fitting? or will I need to find a compression fitting to clamp on the hard line wherever I decide to cut it? What is the OD if I decide to go compression? I would look myself, but my car is at home and I would like to order this stuff now. Need to get a damn flaring tool really.

With this, I am trying to add a PS cooler to my system, since I overheat the living crap out of it!! Thanks dallas.

I ordered Fragola fittings off amazon.

Here are the part numbers;
209006
491963

Comes out to just a fart more than 20 bucks. Not bad. Whatever. Its done.

These are the most excellent flare nut wrenches my coworker lends to me on the as needed basis. Extremely nice set. I would not spend more or less for a set honestly. Coworker is a real nice guy for letting me borrow them really..

Wishing I went all out on the PS system now. Really starting to kick myself now. I did spray those fittings on the box and it came loose RIGHT NOW. I didnt even strain. I started spraying about 3 days ago. Idk who said it was difficult to get them off. Hehe!

Here is an elementary beginning to this project.

I got the cooler attached to the condenser, I got the line semi routed to the reservoir and I figured out I was loosening the wrong hose on the PS gear. I did tighten the other up and busted the new one loose easily. Once my damn fittings get here, I'll put the rest of the line off at the gear and take the 5 minutes to plumb the lines in. Should be real easy to do I got the thing all set up and easy to finish from here. Exciting times.

Lord, its a miracle. I got it plumbed in. I got the fittings and everything else all doned up. Just need to raise front end and bleed. Noticed as well that it seems my oil filter adapter is leaking where it meets the block.

I guess Ill need a new gasket or whatever the hell goes up there to make it stop leaking. I will bypass one day, but Im saving that for 2019, if you know what I mean.

So I got the waterpump resealed, got the new TEE in, got the PS cooler installed and ready for action. Now I just need to wrap it up. No pics yet.

So a little update on this...

Its been cold. Its winter time. I cant stand it really.

BUT, I made an interesting observation. And this is for you, 1SLOW. I drive all highway to work. Its like 20-30 degrees as I am headed in usually as well. And never once have I had a problem with losing power steering after driving straight for a long time. And then it occured to me, you dont need a thermostat on a PS system because its hydraulic, you cant freeze the system and 'lose' power steering. Seems obvious enough, and as I was driving I would always think about that but every time I came to an off ramp I had power steering. No matter how cold it was outside.

So I brought up the idea to my coworker and me and him talked about for probably a good 10 minutes and we came to the conclusion that since the system is under so much pressure and stress, you will never have a problem with cold fluid freezing up your power steering. I also raised the fact that people who live up north where it gets into the negatives, never have problems with this kind of stuff. SOmetimes the pump will sit there and whine because the fluid wont flow, but once the system builds just a small amount of heat, it works properly.

So anyway, thats where I stand on the whole thermostat versus nonthermostat argument. You dont need one.

Like any other fluid,P/S becomes thicker as it becomes colder. The present cooler that is so efficient in the summer on road-courses,and auto-x creates this problem in colder temperatures with normal driving. Basically it cools the fluid off faster than the pump,and steering box can add heat. So,over time the fluid becomes colder,and colder. I could have bypassed the cooler when I didn't really need it,but installed thermostat instead. The improvement in cold weather operation was both exceptional,and immediate.

Are you using a stacked plate cooler?? I run 80mph all the way to work. That fluid has to be freezing at that speed. Windchill has to be in negatives at that point and I never have problems. I used a tube and fin cooler.

Windchill has zero effect on inanimate objects. Bottom line is that it was a problem,and now it isn't... Also have a remote aluminum reservoir behind the passenger side headlight that cools the fluid even more compared to the stock reservoir in the stock location.

Perhaps "effect" was a poor choice of words. Wind chill is how the temperature "feels" to us. While it does remove heat from things more quickly,it can't make them any colder than the actual air temperature regardless how fast the air is moving...

Explain why when you drive through water at fast speed it then turns into ice in your wheel wells. I read that same crap too. Windchill only exists for humans. Bullcrap, real world experience tells you that when something is exposed to wind, it feels colder. Doesn't matter the object. How would wind know the difference between an inanimate and animate object? Not trying to start an argument, but I used to think that too until one day I made yet another observation about the water and how when it gets on your vehicle it freezes, given conditions are correct.

Could be evaporative cooling, depending on conditions. Years ago I worked for the forest service in Arizona. We used to strap these water containers on the front of our work vans. They would slowly seep water through the skin.

Could be 110 degrees outside, by the time we got to the job, ice cold water. You need low humidity for this to work really well though. We don't use them in Florida. :)

It "feels" colder because it removes internal heat more quickly. It still can't drop the temperature of any object lower than the actual air temperature. If air temperature is below 32 degrees,then water can/will freeze.
