champagnegold 0 Report post Posted July 16, 2004 I just replaced my tired old radiator with a new high efficiency 3+ core radiator from NPD. Now after driving it seeps coolant out near the top of the radiator and collects in the top row channel. Doesn't look like it's coming from the overflow outlet (I've got a hose and clamp attached and routed to an overflow catch can.) Could it be the radiator cap? I put on a new 15-18 psi cap. Any thoughts? Thanks Share this post Link to post Share on other sites
