replace them...and while your at it, and if your wallet lets you, replace your water pump while all that stuff is out. I had the same problems with mine last year and all three were replaced and it works great now.

mY ex-02 KJ had a cracked radiator and the coolant leaked very slowly, so it wasn't noticable until the radiator was almost bone-dry and the vehicle started overheating. had to get a new radiator only, and that was enough to fix the issue.

Had a minute radiator crack show up on my wife's 2002 KJ. It was high up on the plastic reservoir right behind the rubber air dam on the drivers side. New radiator was $175 at Autozone so I used JB Weld to fix the old one Was able to just drain the radiator and epoxy it without removing it. The repair worked great, but have never seen a radiator reservoir crack like that for no apparent reason such as stress or overheating.

I see about 2-3 cracked plastic tanks on radiators a week,it happens and there is no fix that will last very long besides replacement.

Thanks for the heads up. The hole was tiny but dissimiliar material expansion rates are a powerful force. I will keep an eye on the repair and see how long it holds up.

it happened to mine about 2 yrs ago. I bought a new one and replaced it myself. I think the aftermarket one is better than the stock IMO.
