You would test your viscous fan clutch with a rolled up newspaper. If it stops the fan blade, your viscous fan clutch is weak or bad.
The old water pump has the proper cast impellers; hoping that the one you installed has the same. Some new ones have impellers which are not cast - they look more like slanted metal fins and are not as durable. I do wonder however about the scoring; do not remember seeing that when I replaced my water pump about ten years ago (as it turned out the original water pump was 35 years old and was still perfect - the squealing that I thought came from a bad water pump was just a bad belt).
Interesting thread.

The pump I installed was exactly the same! I bet the P.O. and myself bought them from the same fella based on some of the part kits that came with the car. Rhymes with shmercedes shmource. If I’m understanding correctly, the advice above about the fan clutch was that when the engine is hot, the fan clutch is “engaged” and the fan should not free-wheel. So, I got the engine hot and then turned it off to see whether the fan continued freewheeling (clutch non functioning) or stopped spinning shortly after engine shutoff due to properly engaged clutch.
EDIT: Of course…if the radiator isn’t getting that hot due to low flow, then maybe the fan clutch won’t fully engage. Just a thought!
