Questions about this item
How do I install the DORMAN 620-653 Dual Fan engine tool, and what is the common mistake?
Position the tool jaws over the fan clutch nut and the water pump pulley bolts; the step often missed is tightening the pulley-holding arms before applying torque to the clutch nut.
What maintenance or replacement will the 620-653 Dual Fan tool need later?
Lubricate the threaded rod and pivot points after each use; replace the tool if the drive square cracks or the adjustment threads strip.
What limit appears first on the 620-653 Dual Fan tool during sustained heavy use?
The adjustable arms can flex under maximum torque, so the practical limit is the point where arm deflection prevents full engagement on the pulley bolts.
