It depends where it's leaking.

If it's just a crack in one of the tanks or neck of the radiator, you can drain it, sand down the area of the crack, and then apply some of the high-strength JB Weld that you can find at an auto parts or home improvement store. Do not use the quick-set - it doesn't hold as well.

Your post is rather vague and the information not specific enough to answer your question.

Where exactly is it leaking? Is it leaking at the reservoir? Is a seam leaking? Is a connector leaking? Is there a leak in one of the cooling tubes/fins?

How much is it leaking? Is it leaking a drop an hour or a gallon an hour?

Depending upon the details you provide your answer will vary widely from :

- simple fix - pour in some silver solder powder
- clean and apply Weld like JB described
- replace an o-ring
- remove the radiator, weld the spot
- remove the radiator, replace the gaskets
- remove and replace the radiator

In order to help you, you need to provide more details.

Try the JB weld approach if you can get to where it's leaking. Drain the level a bit, make sure the area is dry, and then scuff up the plastic a little bit before applying the JB.

You may have to remove the top cover and/or fan shroud to actually reach parts of it.
