My car has fallen victim to the sudden coolant loss phenomenon that i've read so much about. In this case, the upper water pump seal is to blame. I've read posts suggesting that i go ahead and replace the entire pump and timing belt. I'd like to go ahead and do that but i'm wondering if an inexperienced person such as myself can handle that kind of task without getting into something i can't handle. My only mechanical experiences have been replacing the Air mass meter, and removing/cleaning the Throttle body. (aside from the usual oil change). Just wondering if this is something i should attempt, or should i just go ahead and start filling out a check to the local repairman? Thanks!
