Radiator cooler caps

[pink aar]

Can anyone tell me were I can find the correct caps that go on the radiator cooler lines ( at the bottom of the radiator) . The nipples on the radiator for the transmission cooler lines. Thanks again

I'm not sure exactly what you're needing. Caps?

Are you looking for the fittings that screw into the radiator's bottom tank?  Are you looking for the female fittings that are on the ends of the cooler lines?  Or are you looking for an actual "cap" to plug off the cooler line fittings on the rad?

Are you looking to cap off the radiator cooler line in/out ports because you're running a manual trans?

[pink aar]

Correct. I have a 4 speed. I want to cap off the transmission line cooler on the radiator.

[Burdar]

It's not necessary to cap them off.  You can just leave them open.

[Burdar]

If you really want to cap them off for some reason, the fittings are 1/8 NPT.  You could buy some 1/8 NPT to 6AN fittings for the radiator and then use some 6AN caps.

I believe you can buy just the cap at a good hardware store.

Were they capped from the factory???

I don't think manual trans radiators had the cooler tank in the radiator.(no threaded holes in the lower tank for any fittings)

I used to have a manual trans Dakota.  The rad had threaded holes but not fittings in it.  I ran it for years that way...no plugs.  The cooler tank is separated from the radiator so there is no need for a plug.  If coolant starts leaking out one of the trans cooler holes, your radiator has problems.

FWIW, the Original 26" Rad on my 4 spd AAR has the AT Cooling Holes in the bottom and they are capped with threaded plugs.

That's what I've been typically finding.

   They're not capped...they're plugged.

[Jim AAR]

My bad, guess I should have said "SEALED with threaded plugs" instead of "CAPPED with threaded plugs".

I would think that 95% of the people that are on this forum would have understood what I meant either way though, considering I used the word "plugs.

Searched 1/8 NPT Plug revealed many options including https://www.summitracing.com/parts/ear-at993301erl

That's what they look like.
