    Replacement Radiator Question

    Hello,
    My radiator cracked at the tank and I bought a replacement radiator. I got it off of genesisautoparts.com There were two available, 1 and 2 row. I figure why not pay a bit more and get a more efficient radiator. I got via FedEx and took it out and noticed 2 AN fittings on it that are not on my old radiator, the rest match perfectly.
    Here is a picture of what I'm talking:
    Old radiator:
    New radiator:

    I filled up the new radiator with water and it wasn't leaking from the 2 extra fittings, it seems the 2 row in the radiator is separated. So I'm pretty sure those are for extra component cooling, like power steering or engine oil.

    My question is, if I can't return this one for a regular 1 row radiator, can I just keep this one and do I need to weld/plug those fittings securely?

    I take it your car is a 6 speed manual? Those fittings are for auto tranny cooler lines. I'd plug them, so crap doesnt get in there.

    Thanks for the welcome and for such quick replies guys.

    Here is the description of the radiator that I got:
    http://www.genesisautoparts.com/radi...t7l_v8_350.htm

    I got the 2 row radiator. Is the 2nd row for transmission cooling or is it a more efficient radiator?

    If it's a more efficient radiator, I'm thinking of sticking with it.

    Is it really necessary to plug it, I mean what could get in there at that angle, mostly water, right?

    Thanks, guys.

    No, but why half-ass it. All you need is a couple of fittings, and it will keep things from building up in there over time, and could help the radiator last longer.
