Sometimes I can't help being the antagonist, in order to bring some intelligent debate? :hello1:
If mechanical fan clutches were as efficient as temperature controls are things would be different. During periods of max cooling requirement a fully locked up mechanical fan is hard to beat. Cruising over 30 mph I do agree that mechanical fans don't completely unlock causing some loss in efficiency.
Now a clutch driven mechanical fan with a telemetry ring for control Hmm????? :happy3:
