Late to add this as I finished it last week, but with 155K, I smelled a slight coolant odor at a light, then again at another light but nothing after that. Given the mileage and the OE water pump, I figured I would do some prevent/required maintenance.
Looks like there may have been what appears to be the start of a leak into one of the mounting bolt holes.

So I went ahead and replaced the pump, hoses, T-fittings with Dorman aluminum fittings, OE pump with thermostat, as well as OE oil cooler lines, front main seal and new balancer. I did not use the plastic T- fitting in the pic. I also used the Dorman heater hose which also uses an aluminum fitting.
