    Can't win. I was slowly loosing coolant for a while but now it has gotten worse. It appears to be leaking out the bottom of the radiator. I am assuming this means somewhere internally it is cracked/corroded and leaking out the bottom?

    The rad actually looks super clean and no damage to the metal/fins around it.
    Your thoughts appreciated as I have never dealt with a leaky rad before.
    Should I just replace it?

    Yes, best option is to just replace it. They are not that expensive and quite easy to do. I believe there are a couple write ups on the process as well. I'll see if I can find the links for you.

    I suppose that's what ill have to do. It's weird because it looks to be so clean. But I guess it is internally.

    Can you tell it is factory or just guessing? I've got the original still in a 06 Tacoma. :)

    Another random video. Just to show its not leaking from the cap or reservoir bottle. Hoses and hose clamps kind of need replacing but I don't think its the source of the leak. The weird thing is I hadn't started it for a couple of days and it really was pouring out pretty good. Now when I start it up again for this video it's back to a relatively slow leak

    Should I bother with the water pump? Anything else?

    denso rad and Aisin water pump are best?

    I normally just do the radiator with a new cap and upper/lower hoses and don't forget the coolant.

    While you're in there and all the coolant is out, a thermostat and a water pump wouldn't be such a bad idea.
