The radiator is ok at best. It does its job. Had mine for a little under a year, and it sprung a leak. Right side, near the tanks. Emailed LMR and talked to the representative, who asked for photos, and i provided them photos. They asked for photos that show the leak (which is impossible if its single frame photo), told them so, and they said ok thats fine, we can change it for this time. After speaking with the rep, i chose to pay for a new unit, received it, destroy the original one, and get a refund. Did so, sent photos, i get a refund for $145, which is what i paid for the original one on a black friday sale. Confused, because i understood that i would get refunded for the $220 i paid for the exchange. Turns out, thats how not it works. If you got it on sale, and warranty it, you pay the difference. I was PO, and the rep was trying his hardest, but the managers didnt care. And their warranty online does not state that you need to pay for the difference. But they "met me half way" and gave me half of the difference. So, good luck. When i build my motor, i am going for the Ron Davis unit. Those are so much better and nicer.
