I have a little bit of coolant seepage out the top of the radiator on my 300D. It appears to be leaking out around the metal-to-plastic "crimp" looking edge, running around the top edge of the rad, right next to the air intake.

I replaced the radiator last August, so it doesn't seem that it should be leaking quite yet.

Is there a way to "tighten" that connection together a little bit?

If you try it, you could make it worse. Maybe let a radiator shop take a crack at it? Is this a new replacement radiator that might have a warranty still?

If its new make a warranty claim. If they see marks where you tried to compress the joint they will deny any claim.

My thoughts exactly. I don't know how long the warranty lasts, but it can't be shorter than 8 months!

(I suppose it could be shorter than that...although, here's hoping it's not)

Thanks.
