98 Expedition 5.4 and 03 Suburban 1500 5.3
In another thread, I was discussing an intermittent AC issue on my Suburban. Could be a bad fan clutch.
The Suburban - when cold, fan will move by hand easily, will spin with little resistance about 3/4 turn. Get engine at idle up to operating temperature, shut off engine, spins the same, no change in resistance.
I tried to compare to Expedition - Same identical feel and spinning as Suburban at cold and at hot idle after shutdown, only difference is the Expedition has a tighter feel on the spin at 1 portion of the revolution, Suburban is consistent entire revolution.
I would think as the vehicles get up to operating temperatures, the fan clutches should get tighter?
Questions:
1) Any other way to troubleshoot and diagnose failing clutch fans?
2) Could both fans be bad? or maybe both fans are good? They both feel the same at cold and hot temperatures
3) If I need new clutches, any solid recommendations on aftermarket vs OEM?
