Do not cut corners! I did! I only replaced the water pump because I did all new pulleys. Three weeks later the thermostat went, two weeks after that expansion tank. Replace all 3 and atleast the upper radiator hose. None of them are hard at all. Get the fan off and your looking at 30 mins of work for each if you work slow.
