2006 1500 4.7L, manual transmission, about 55k miles. Pretty much everything still original other than the battery.

Twice in the past two weeks I've seen a small puddle directly under the radiator. It's been in the morning after 80-ish degree days/60-ish degree nights. It hasn't been enough to make me need to add to the overflow tank or cause any on-road problems. But I want to make sure it's not an indication of some trouble brewing.

See photos attached. #1 is shot from the driver's side directly under the radiator. You can kind of see the drip spot on the closest bracket. #2 is a close up. #3 is shot from above directly above the leaky spot. I don't see any other obvious sign of the leak, in case it has just collected down on that bracket from somewhere else.

Anyone have any idea what the problem may be? I don't really have any other problems with the truck short of some occasional vacuum pressure problems, though I don't know that that'd be related to this.

 

Most common it the seal between the plastic tanks and the aluminum center. I think a new radiator is in your near future.

 

You were supposed to say "oh yeah, easy way to fix that."

Oh well...outside of routine maintenance, I haven't put much money into it, so I guess it's time.

 

But changing the rad is an easy fix....LOL
