First of all fine the source of the leak before buying parts, not after. Check the plastic elbows that the heater hoses connect to. They are notorious for failing. Replace them with metal ones. Actually, even if they're not leaking, while you're fixing the actual leak change the plastic elbows as well. They are only a few dollars and its only a matter of time till they fail.
