Radiator connection question
So my radiator finally bit the dust and am now getting to put it in. I ran into a little snapfoo with the new radiator. I have two copper fittings that I have no idea what they are for and if I can leave them as is. To explain, I am providing a picture of the said items in question.
I bought this radiator at oreilly's today. I called them and they are clueless to what I am talking about. Even showing them, they were still clueless. I have a smaller radiator in front of my radiator and am assuming that is my oil or transmission cooler.

So again, my questions are:
1. Oil/Transmission Cooler??
2. Can I leave them uncapped?

Cool, thanks! Right now I am just trying to get her back on the road. I can probably make it an oil cooler at another date & time. Although is the processes all that hard to make it into an oil cooler? Can I leave them as is with those rubber caps on or do I need to cap them off before I fill the rad with juice??

You can leave the caps on there, should be no pressure and no coolant in them.
The stock oil cooler does a good enough job that running the oil through that cooler would just be a restriction.
All oil from the oil pump goes out through the side of the block into the stock oil cooler, then to the oil filter before it ever goes in the engine oil passages.

What Dave said, do not make this into an oil cooler. It is a transmission cooler for trucks with automatic transmissions, but works good as a fuel heater as well (if you run stuff like WMO and such that should be heated before it reaches the IP). If you have an automatic trans then run this cooler between the trans and the external cooler you have now.
