In the Dakota, the PCM kicks the fan on at 210º coolant temp. The temp sender is on the outlet of the engine. Monitoring the PCMs temp signal showed that the engine ran no more than 10º hotter when simply removing the clutch fan. Fixing the non-problem brought it right down to where it was before hand.
For normal driving, the clutch fan is not needed. It's there for towing, extreme ambient temp and low speed service. All of these circumstances are ones that I would recommend putting it back on. Not sure of space available with the WK fan shroud, but it took all of 2 minutes to put it back on my Dakota.
Bottom line, if you don't want to do it, don't. Don't crucify this guy because he did.
Tint, Superchips, SRT intake tube, Gibson catback, catch can. One hardcore DD/kid hauler...yeah.
