Loss of Power after New Fan Clutch
Hello Everyone, I have a 2007 Dodge Ram 1500 5.7 and it blew the water pump and fan clutch at the campsite. Got it towed to a auto repair store in San Diego and they replaced the fan clutch, water...

Roy, Neighbors truck is 5L. I don't think one can assume everything in back of the fan is the same though. Different engines have VERY different thermal efficiencies and thus, different cooling needs. Shape of rad probably dictates fan type and configuration too. Calculating cooling requirements is over my pay grade!
Devo, that is a complicated question. Under the conditions you state, it probably takes no power at all - fan can be disconnected. But When conditions are at their worst, like climbing mountain w/AC and heavy trailer, it takes a lot of power My truck uses up to 23 HP just to turn the fan.
My advice to the OP is to live with it for a while. Better to have ample cooling than more speed. Also, don't jump into doing some kind of modifications when what you have works.
As a side note and I don't know if this is true for 1500's, but when it comes to clutch fans for Ram/Cummins, only the OEM will do. Aftermarket clutches are notorious for having performance problems.
If the problem is really bothering you, ask if they put an OEM clutch on. They are stupid expensive but work great because Ram continues to revise them for both better cooling and AC performance. Last year I replaced mine and it works better than when it was new (but again, it's a diesel).
