Patrick H You can not "over fill" a radiator. To the OP, it's near impossible to tell you where your exact leak is in the pics. Chances are it's the radiator (usually a seam on a composite radiator).

IMO, yes, leaking from the top seam. That is where mine was leaking. As I said before, you can pull it and have a rad shop put new gaskets on the tanks, but since you have to go to all that trouble anyway, just buy a new one. A high-end aluminum with welded tanks can cost ~ $400, but I did find a reasonably-priced aluminum one off of eBay that is holding up nicely, ran me around ~ $200.

stonewall_jeep I had one in my 2000, would leak antifreeze from the top and drip all the way down. Found out it was because I overfilled it with antifreeze

jjone54 01 sport 4.0, radiator does not look original but is the plastic top, has 104k does not look like from top at all, ill check drain petcock tomorrow, the coolant is sitting on bottom frame of radiator and drip straight down on the draglink

JFjeld Dripping near the petcock/drain? Are you sure it's not coming from the top and just collecting at the bottom? What year Jeep? Is it the original radiator with the plastic tanks? At least on the TJ, these are notorious for leaking at the seams; I've been through two.

You should be able to take it to a shop and have it pressure tested, but better to have an idea specifically from where it is leaking. If it is leaking at the seams, your best bet is to go with an aluminum radiator if you can afford it; the tanks are typically TIG welded to the core.

Radiator leak

My radiator started a leak today its right at bottom facing engine, could it be bad radiator or something fixable without replacement?
