Thermostat seems to take longer before it opens and maintains operating temp. It used to open when it hit "12:00" on the gage and now it's more like "1:00." Once it opens, it holds 10-11:00. It's time to replace the antifreeze too. Hoses (and water pump) are original. I assume that replacing the hoses is a no-brainer. Your thoughts on the water pump and anything else?
