Car Forum / Jeep / February 2007Plugging A/T lines on replacement TJ radiator???
Hope someone can help me here. I made the mistake of ordering a replacement radiator my `97 TJ from an online parts supplier. Stupid! The repl radiator has brass or copper fittings to attach automatic transmission lines to, but I have a 5-spd. (OEM doesn't have those fittings/openings.) Rather than going thru the aggravation of returning it, can anyone recommend a good way to block off those A/T fittings? Repl didn't come with any plugs, other than rubber boots that fit over each of the fittings. Thanks JohnM The rubber boots work. You can just go get a threaded plug for the holes too. I 'think' they are standard pipe threads. Mike 86/00 CJ7 Laredo, 33x9.5 BFG Muds, 'glass nose to tail in '00 88 Cherokee 235 BFG AT's Canadian Off Road Trips Photos: Non members can still view!

Now what you are contemplating is a restriction more than it is a cooler.

If he wants to find > out let us know... Long as you use the return side pressure wouldn't be an issue, but actually it's going to heat the fluid up more than it cools it down. I'd just put a couple of plugs in there and be done with it. >> Why bother, just leave them alone as they are not open to the >> radiator coolant.

The transmission cooler is sealed from the radiator tank, and nothing will leak out of those fittings. Just hook up the radiator, fill with coolant, and proceed as normal.

By default, most parts suppliers sell you an AT rad. When you install it, just leave the plugs in place in case you have a major problem and need to use your current vehicle for parts on an AT Jeep. The AT rad is fine for manual transmission. You did not make a stupid mistake.

There is no difference except the plugs and a tiny line inside the rad. Leave the plugs and be done with it. If you are sweating keeping them sealed, apply a small amount of glue or gasket sealer to the plug and put it back on. You did not make a mistake.
