new automatic radiator on a manual 3.4

hey TW, wondering if you can help me here.

I have the lower fittings on my new radiator for an automatic transmission capped with the thin rubber caps (My truck in Manual) that were already on there when I received it from Denso. do I need some beefier caps on there or will those be fine? really just trying to figure out if there is hot coolant against those caps or if that section just stay empty because I dont have the auto trans setup to it?

 

Those tube lead to an empty cavity inside, you don't need to cap them.

 

awesome thank you for the quick response!
