Just passed 200k miles. The coupling for the water pump (a sleeve bushing) "wore down" inside at the cam spline end, which is also a bit worn. So next time you change the pump, check the coupling for wear.
Got it fixed at a good shop in Port Aransas. Coupling was a bit hard to find and also pricey.
But now I have a mystery for the experts. Start engine, use climate control trick to track coolant temp, it gets to about 110 and starts to oscillate between 108 maybe and 120, back and forth thru the numbers for about a minute, locks on 135 and SES lite comes on. Now figure that one out. No fair scanning.
