    Aluminum Radiator Blues

    Hi
    Folks I just had to share this one with you. I was all excited back in march when I purchased my aluminum CSF radiator
    Only 7 months old and I sprung a major leak today. I thought this radiator was going to be so tough and durable.
    Has this happened to any members here? My luck....

    Yeah you're not the first, several others got leaks and last i read csf said it was an issue with their first batch that they corrected later on (although your radiator should be from the newer ones)

    They are known to spring leaks, though on the bright side at least it's an external leak. I would probably go with one of the Davis radiators if I wanted the shiny with extra cooling but they cost a small fortune and don't leak.

    Mine is leaking too but only seems to do it once the radiator comes up to temp. Really frustrating since we put one in our 6.0l swapped truck to and now I don't trust it

    My plastic OEM one doesn't leak . But seriously, that's a bummer especially when you spend big $$$.

    So CSF won't send me a replacement radiator because according to them I didn't buy mine directly from them. I bought mine from an eBay seller who wanted
    me to deal directly with CSF. I explained to him the response I got from the MFG and he better get me a replacement, because my radiator is only 7 months old
    and is still under warranty. I filed a grievance with eBay, PayPal and my Credit card. So while they point fingers at each other I bought Foreign made plastic radiator

    Did you take the CSF to a radiator shop and have them pressure test it to find the leak? Could be a simple fix.

    Could have just bought a Delco radiator and put in a cooler if your worried about the trans and been done with it. If that is one of those Spectra radiators plan on doing the job a third time.

    I just had the tranny beefed up and worked great for 1700 miles when the internal trans cooler failed. Yuck, I'm having a new radiator built like we used to do back in the day for cars we raced. It is even cheaper than a GM but built by locals I have used for many years. Transmission guy is flushing the tran to see what got ruined. Oh well, first expense I have had on my 2008 H3 Alpha that was not elective.
    About to hit 100,000 miles and running good.

    Ouch, sorry to hear about that. Hope it's not too painful of a repair.
