Well I replaced the water pump, thermostat, and bought a used radiator that appears to be in good shape. The knock is completely gone and it actually sounds better than when I bought it! (After I had to return the first water pump since it has a reverse rotation.) However, it is over heating. There are no leaks, I sealed the gaskets, and the radiator is filled. Is it possible that I have bought a bad thermostat. I checked the upper hose and it seems to have pressure and is heating up along with the engine so I don't believe it is stuck shut. Any ideas?
