Delco Water pump and metal gasket are on the way and should arrive tomorrow. Should I also replace the fan clutch while I have everything taken apart? It's on the original fan clutch (and water pump) with 11 years and 126,000 miles. Fan is always on at startup, but when you rev it up to 2500 it always disengages. It does seem to engage a lot in stop and go traffic, especially when the humidity is higher outside.
