    How to clean out radiator

    Hey guys, I need to clean out my radiator. It is full of rusty sludge, and it is not in my car at the moment. I got it off of a parts car, and need to put it on mine, but I need it clean first. Again, the radiator is not connected to anything. It is off of my car. Anyone?

    I cleaned mine by hooking up my water hose to the top and running it through for a couple min. It's kinda messy but I don't know of a better way. Although mine was hooked up to my car so maybe you could stop up the pipes going to the engine. Mine was all rusty and now its all clean. Good luck

    CLR works well on the crap that builds in rads, but don't leave it in there too long...stuff is a little hard on aluminum IIRC. Most hardware stores should have it.

    Take it to a radiator shop and tell them to rod it out. They will take the top and bottom tanks off, rod out the cooling tubes, and reassemble. Should not charge you too much and you will know it is clean and won't need to worry about all the crud getting into the engine, heater core etc. Well worth the money if it is that bad!!

    If you don't want to use Ebay, try a local aftermarket radiator supply store. Call a few body shops, they buy them all the time, and if you ask nice, they might even cut you a good deal, like cost +5% if you pay in cash. (Shops get them for aprox 100 list, but really pay like 75 for them.)
    The other option is to replace the core, most radiator shops sell cores, and you reuse the end tanks, but that is not always the best choice cost wise. Do some calling around and see what you can find.
    I just flushed out mine with clean water, and it was good. Use the CLR, and see how that turns out, remember to flush out your radiator with lots of clean water though, the CLR will clean up any deposits you might have, but it will reveal any leaks too.

    $125 shipped new off ebay. I'd rather be safe myself and not take any chances. Think of it as $125 vs possible overheating, failure, You being pissed off, and more down time for the supra. If its not that old I guess just clean it. But if it came from the factory in the car dude just replace it.
