Okay...the next step:

- I will take the car out today and drive up the hill. According to the other thread, once the car gets really hot, I'll pull over, turn off the engine and check to see if the fan stops spinning after less than five rotations. I understand this will tell me if the fan clutch is worn.

- secondly, I may have to flush the cooling system. I trust this is quite simply to open the drain valves and then flush it with a hose and refill?

I'll report back in a couple of hours on the status of the clutch.

Wish me luck in getting back up the hill.

Brad.
