where can you get those T things?

 

So in everyones opinion, is is just as good to use the t-fitting as installing a newer radiator? I have to buy a new rad soon and found a good price on one for my 90 but it is the oder style.

 

this up grade is for installing a new radiator with a radiator cap on it the reason i did mine this way it was cheaper than buying the 89 radiator and the t fitting in the top hose call and see which is cheaper in your area

 

Its a major PITA to find these "T's" in the Milwaukee area.

I called Advance, Auto Zone, Checker/O'Reily and none had them.

Finally got ahold of one from my local Napa. According to them they keep it in stock here for all the "race car" guys. I'm not sure if all of them stock the T's, but mine told me they could order other sizes as well, so I'm guessing any NAPA should be able to order them.

The 1 1/2" diameter one goes for something like $35, but I think our upper hoses are 1 1/4" instead.

 

Ok so I am still trying to figure this out, I have an 88 with the closed system. I am getting ready to purchase a new radiator, so if I buy a radiator FOR an 88, install this T fitting, add an overflow tank and routed the line from the T to the overflow tank, is that all I have to do? Could I then pitch the expansion bottle?

 

you also connect the two lines from the old tank together

 

Awesome, that sounds pretty dang easy.. Thanks for the info

 

Ok one more question. If you do this t-fitting setup, what do you use for a return line from the overflow tank back to the cooling system?

 

if your buying a new radiator get a 91 and up and just buy the over flo bottle run the heater hose straight to the heater core and be done with it

 

Is there a good write-up of that process? And how is that better then the T fitting idea? thanks!

 

I don't meen to hijack, but if I have an '88 will a '92 radiator work for the upgrade?

 

I was sittin in Carls Junior drive thru today when i could see my temp rising. Then i saw the reflection of my jeep in the window and saw a puddle forming under it. Yeah, the whold damn cap blew off the pressure bottle. That's when i decided i'm done with it. so my next mod will be switching to this system. If i have any questions that i can't find here, I'll hit this up!

Thanks for the help, btw with the write up!

 

after 15 years with the same xj i could not buy a nother pressure bottle or cap either this solves the issue.

 

Yep I'm doin this. Do you have any pic of how youve got all the hoses?

 

i eliminated the heater control valve plumed straight to core if you core leake just loop the hoses to each other no issue by passing valve
