CSF 3-Row Radiators- NOT Discontinued!

Also make sure you have the right style of cap.

Some caps don't have a sealing gasket in the upper part of the cap and won't seal properly...

Both the caps i tried had both gaskets.

If the cap is leaking out the top, (after 2 caps) the seal just about has to be bad.
Did you get it from me? If so, drop me a PM or e-mail and we'll get it straightened out.

If not, I'd contact whoever you got it from and get a replacement.

It was slightly bent at the top of the rad. I straightened it out and all seems good now.

These rads are traditional copper/brass construction so the metal is softer.

Sometimes in shipping the top can get bent slightly. It can usually be straightened easily in cases like that- as long as it's not creased or badly bent.
Then, you'd need a replacement.
