I replaced my water pump 119k. I did not replace fan clutch or thermostate at that time, short on funds. The TB has 121k on it now. I did replace the Dexcool at 97k. I plan on taking a long trip pulling a travel trailer in the near future. Do you think I shoould replace the fan clutch and thermosate, the TB is running in the normal temp range. When changing the water pump, I checked the clutch, it did not have any play or wobble, but only rotataes a short distance, less than a quater turn is that normal?
