I can not remember the last time I replaced a water pump on anything except my GMC. I always throw one can of water pump lube (around $3.00) in to any antifreeze change. I have around 250,000 miles and 20 years on my GMC. Over 150,000 miles and 19 years on Laurie's Jimmy, and a little less than 150,000 on my 13 year old Colorado.
I replaced my GMC pump about 12 years ago because I could. I used a 4" impeller pump from NAPA.
What kills a pump? In my opinion it is lack of lubrication of the seal, or rust / wear in the bearing. A little lube helps those two even when parked.
Replace the pump while you are there and throw two cans of lube in with 6 gallons of 50/50 mixed fresh antifreeze. I always use $.88 per gallon Walmart distilled water for the mix.
