After replacing rad hoses, I heard noises on the test drive like a flock of sqwarking birds under the hood. I thought water pump is dying now, but no fluid loss. I noticed movement at the pulley when I revved up the engine. After shutting down, I tested for movement by wobbling the fan about. Seems to be too much play there-the whole shaft moves about. Is this a normal thing? During my test drive after replacing rad hoses, the temp soared, but after a rest, the temp for the return home was ok. So, what is the tip? Is it fan clutch, water pump, both maybe? Strange that no more fluid loss is happening.
