1996 Plymouth Voyager Engine noises after replacing radiato

After a 250 mile drive, noticed steam emitting from the engine, with no indication of overheating by the engine temp gauge. When the hood was opened, brother noticed a pin hole break in the large radiator hose where one of the spark plug wires runs close to the clamp and hose. Antifreeze had sprayed over the engine. He replaced the hose and clamp, but now there's a steady speed correlated ticking noise. We applied belt dressing and drove 250 miles home, but the noise is louder than ever. The belt looks okay, so does it need tightening? Or is there a water pump problem? Should we go to a auto place like PepBoys or to the dealer for help?
