Why I installed a low temp thermostat.

Yep, at 94K miles my original water pump began to weep a bit and since it is a known weak link, it had to go. While we were in there a new motorsport 160F T-stat and a few idler pulleys were replaced. 90% of this job is getting the car in the air, accessing the work area and draining and refilling the coolant. I do tend to use ALL of the car so a fresh 160F T-Stat at 94k was a no-brainer.

Would I have gone to the trouble of changing a working T-Stat if my car was only 4 years old, had 20K miles, and the water pump and coolant looked great? Nope.
