On the passenger side on the back side of the rad it is wet from about an inch down from the rad cap. I can't see where it is leaking from but the anti-freeze reservoir level has dropped again. So do you have any ideas where this is coming from. The rad cap is tight and as mentioned is is dry around the rad cap area but damp on the back side of the rad from about an inch down below rad cap to the bottom of the rad on the backside of the rad. Thanks for any replies. Frank

Hi there,

you will have a fatigue crack in a core tube, or the tank seal if a side mounted tank, you will have to have it inspected by a radiator shop to evaluate the repair. the longer you leave it the worse it will get.
