Today, I replaced the thermostat. I was going to also replace the water pump but after a hands-on inspection, I found nothing wrong with it. The pump's manufacture date was 5-05. Amazing, after 10 years and 108000+ miles, the pump was still in excellent shape. No grinding noise what-so-ever when I spun it. I had read stories on here about pumps going bad well before 100000 miles, must be my luck, I guess. Anyways, coolant temperature is dead center on my dash, happy as hell.
