Definitely the radiator.
How many miles is on the vehicle?

If the expansion tank is original, then I would highly suggest you replace it too. You don't want an old exp. tank to fail on you, it will be more costly than a failed clutch.

In fact, I would highly recommend you save up the funds to do a complete cooling system refresh.
