Today I dropped off my CSF radiator. If its going to cost me too much to repair it then I'll probably just end up buying another. Not really sure why but they said they made need to remove the entire tank if the crack is from the core to the tank. And upwards of 175$. That's just ridiculous. I said call me before you do anything to it. Has anyone had any luck JB welding aluminum radiators? If the cracks on the horizontal part where it mates with the side tank couldn't I just pull back some fins and JB weld inside of it and use a tooth pick to spread it around? It's gotta be pin hole sized because it wouldn't leak without the coolant at operating temps. And it would just hiss as it barely came out. Sent from my Pixel using Tapatalk
I have used JB on a gas tank, it worked great. I don't think I would trust it on the radiator. It may hold fine under pressure but the aluminum radiators will expand and contract at a different rate then the JB. This could cause it to fail.
