One more thing: Am I understanding this (below) correctly?
With a cold engine not running the fan clutch is suppose to slip so that I can reach in and turn the fan without turning the pulley or anything else. When the engine approaches 800 RPM then the fan clutch engages the fan to the pulley so that the fan stops slipping and spins at the same RPM as the engine.
The clutch will prevent the fan from exceeding 3100 RPM regardless of temperature. If the air temperature on the fan clutch is cool (like driving in -30 F) then the fan clutch will disengage letting the fan slip free of the shaft when the engine speed is over 800 RPM, but when I pull up to a stop sign and the engine RPM slows to about 800 RPM then the fan clutch will reengage and start spinning the fan fast until the engine RPM is increased again.
yes rule 1 is regardless of temp
this is suzuki docs
rule too is the tricky one, it slips above 800, cold, but will be below 800 rpm but slips, it will.
until hot, then is locked until max RPM is hit and then slips again, above 4000, limits to 3100, so the plastic fan does not fly to bits (explode, etc)
