So my radiator sprung a leak, but when I went to buy a replacement they all show additional connectors at the bottom of the radiator tank. Mine does not have two extra outlets. Assuming that's for a trans cooler?

Am I thinking right I can just screw in plug caps on those connectors? Just making sure.

Driving a 6 cyl - 5 speed 1994 YJ SE

Thanks -

Yes that is a trans cooler. You can plug them if you want. It is not really necessary though.

Yeah, it is hard to find radiators that don't have the trans cooler built in. It's a supply chain issue - cheaper to just put it in them all rather than build and stock twice as many variants. I usually just leave the plastic thread protection plugs in place. Using actual plugs would be a nice touch, since rads have been known to leak between the coolant and trans fluid sides, but finding plugs in the correct form is a PITA and not really needed.

I left the plastic plugs in mine but they've fallen out at some point. I've considered plumbing a quick release at either side so I could hook a hose to a 12v pump and a bucket of water for some nice hot camp showers. (y)
