944 Water pump, to change or not to change ?
Hi all, I have a 1987 944 N/A with only 67K original miles, water pump changed 5 years and 8,000 miles ago. No bearing noise
is evident and I am jus going to do the timing and balance shaft belts, rollers and tensioners. Would you recommend changing
the water pump, or it should be fine with only 8K miles ? I know many of you have much experience with this subject and thanks in advance
for your recommendations.

Should be fine. Might want to look at the bolts and studs carefully though. If you see any sign of corrosion. Than change it now before full electrolysis kicks in next time.

I change mine every other TB change, which I change every 5 years.
My WP was going fine after 10 years when I changed it last year. It's in my basement, want it? J/K!

Just another data point. I bought my car when it was about 12 years old with 32k miles. The factory original water pump went out and started leaking almost as soon as I bought the car. I changed it with a LASO rebuild, and that one lasted 10 years and 40k miles, and was still going strong with I pulled that motor out of the car. On the new motor, I installed another LASO rebuild 12 years ago and it's doing fine 34k miles later. I'm doing the belts now myself, and am opting to change the pump. I figure if the brand new one failed at about this age/mileage, then there's a decent chance this rebuild will go out before the next belt change. I also worry about the little block studs corroding to the point of no return if I leave them in there too long. (And am hoping it hasn't been too long as is, since I see some corrosion on one of the studs!)

Well I got that pump off and am glad I did. The main bearing has noticeable play compared to the new one, and the rubber seal in the throat of the thermostat area is shot. Some percentage of the flow was just spinning around in that bypass area. At any rate, glad I pulled it out now that I've checked it.
