So, looks like a water pump is in my nearish future. I found a tiny bit of dry coolant just under the pulley this weekend doing an oil change. Very small amount, completely dry. Odd. Anyway, going to keep an eye on it, but most likely will be changing it sometime in the near future. The question I have is regarding coolant drainage. I just flushed and replaced my coolant about 2k ago, and would rather not do it again. The 986 service manual mentions using coolant hose clamp/s to minimize the loss of coolant. The question is which lines? Just the line going into the water pump, or both coolant and thermostat? Or, just deal with it and eat 5 gallons of coolant? Another thought is, if drained into a clean bucket, is it reasonable to reuse as the coolant is reletively new?
