My water pump went out at 38k miles....most go out around 50k.....so.....I recommend changin it BEFORE 50k. A buddy from austin had his go out when I was down there. There were about 4 of us drivin around on a mountain sorta thing...lol Texas doesn't have mountains...lol.....and his quit on him....in a BAD spot. Changin the water pump out is farely simple....Chris Hightower has some pics of mine when we changed it out. Replace the thermostat too....might as well while you've got it apart. FYI
