Engine is overheating. within 15 minutes of operation. on 1997 Lexus ES300

My Lexus is overheating within 15 minutes of running the engine. I think the water pump is not working and needs to be replaced. The car has over 250,000 miles on it. Is the water pump easy to replace? Where can I get a set of instructions to do this job myself?
