I know there has been a lot of talk on the forums about water pumps and now I have one leaking at 132K miles. Small leak at this time and seems to be apparent only after sitting for a few hours. My question at this point is what brand of pump should I look for? Seems I recall there was a suggestion to go to a Caterpillar dealer or direct to a Cummins source. I would like to get the part in hand before starting the job. The only parts store I have nearby is an O'Rileys. Have not heard good news on later model pumps from them.
