Radiator Leak

[Caleb S]

The top of my radiator has a small area (size of a 50 cent piece) that is green and hard when the radiator is cold. When hot the green material gets soft and there is coolant leaking out. I'v owned the car for over 10 yrs and never noticed the "green" spot or never paid attention since it wasn't leaking. Maybe someone repaired it before?

Can I clean the area up and use some type of JB Weld or what is recommended? It's not a huge leak but I have had to add coolant recently and don't want to get stranded.

Thanks in advance!

If its leaking than replace it. Anything else is just a band-aid.

For every bad spot that you can see there are probably many others that are not quite noticable yet. Best bet is get it replaced, or replace it yourself. They are not all that hard in most instances. Then again I drive trucks and not small cars so it may be a chore. Take care and N Joy the Hunt././Jimbo

I would not do anything with it, until you replace it. It will need to be replaced like said above. If you try anything, most likely a larger leak will occur and possibly cause the vehicle to be un-drivable.

What type of truck or car is it?

Good luck.
