Exclamation Help with new radiator!!!

I recently bought a radiator from pro tuning lab and it did not come with the brass connector that connects my lower transmission hose to the radiator with the quick connect. On my old radiator that came with the jeep (94 xj) this part seems as if it is welded to the inside piece. Is there a name for this part and where can I find it, or is there a substitute that would work fine? Preferably don’t want to wait for an item to ship out, so I’d rather do something with the local auto parts stores. Thanks in advance!

What does the outlet look like on the new rad? Just a threaded hole? If so, just get the appropriate fitting from the store of your choice, cut the disconnect off the hose, and use a barbed fitting/clamp.

I tried that yesterday. Since I didn’t have a name for the part, they couldn’t look it up. But yes, it is threaded female on the radiator and matches the top trans line hole exactly.

Just use brass fittings in the proper thread pitch.

It is welded to something inside the radiator...the cooler for the trans fluid. The only reason for the threads you see is to hold it in place in the radiator tank.

It is put in the tank and the nut for those threads tightened before the tank is put on the radiator.

Hey thanks guys, here’s a couple more picture of whats going on.




So the brass fitting is for the top trans line, and it fits both bottom and top. I guess I’m just going to pull another one of these off a Jeep in the junkyard. Any easier way, since my nearest junkyard isn’t very close?

Almost the same issue I had with the aluminum one I tried years ago......but with mine it came with a spigot that was suppose to replace what you are trying to do now, but it didn't clear the body at all.

Had my old one tested to see how bad it leaked, and turns out it didn't....but the drain petcock was loosening up over time.

Sent the aluminum one back, got my money back, and filled the petcock with RTV and put it back in....leak free for the last 4 or 5 yrs.......course it does make draining the rad a bit messier.

Welcome to the computer age where they hire clarinet players right out of high school who think that an engine is a "Turny Thingy" to sell auto parts...

Me "I would like a cam seal/plug for a 300 Ford six"

Counter guy "My computer says the 300 ford never had one that size... ever"

Me "Here's the old one, Do you have a box full of freeze plugs? can you just match it up?"

Counter guy "The computer won't let me because of inventory control and it's not the proper application".

Oh...Man...

I recently picked up new radiator from summit. The fitings were encased in the styrafoam packing. If i hadnt broken the packing apart i'd never seen it

Come to think of it, mine was sort of like that too...the fittings were in the styrofoam ends, but not in a way that it was obvious.

I was pretty pissed, but the summit brand radiator works well and is much nicer ( and costlier) than spectra one.

never could understand why you would want the transmission fluid through the radiator anyway. I run through two coolers but not through the radiator. Keeps the temps below 185 during normal driving. Wheeling hard raises trans fluid temps to 200-220 degrees during the Arizona summers. Don't see how running hot trans fluid through 210 degree water does any good at all. My experience with the AW-4 shows it to heat up quickly if pushed hard. Anyway don't mean to change the topic.

Simple. To cool the transmission fluid.

It doesn't run through 210 degree water. The 210 degree water is in your engine block, not in the radiator. If the water in that side of your radiator is 210 degrees, your cooling system has a serious problem. The water in the cool side of the radiator is much cooler than your hot transmission fluid.

Bring your Jeep up to full operating temperature, take a IR temp reading of the cool side of the radiator. That will do a great job of illustrating why you would want to run the transmission fluid through it.

Try 3/8" inverted flare fitting. Find a shop that makes hydraulic hoses and give them a call or a parts guy that knows his job. You want a push lock fitting that will have barbs to hold on the hose.
