Installing Electric Fan - Some Questions
I must replace my radiator, so I'm considering installing an electric fan and eliminating the factory fan & clutch assembly.
Three questions:
1.
Will installing an electric fan create enough efficiency gains (HP, MPG) to warrant it's installation?
2.
Can I use a temp sensor that is already part of the van's electronics? I seem to remember a sensor (or two) already mounted near the front of the intake manifold, possibly in the coolant jacket.
Of course, I realize the new electric fan will need it's own relay & power.
3.
Is a Single Row radiator appropriate or should I pay the extra money for a Double Row? The van has A/C with an automatic, I never tow anything with it and I carry a light load in the cargo area for my work.
Thanks in advance.

There are a few eFan offerings on the web. JC Whitney, Rockauto, Summit racing and the like. Most for the Dodge setups are a universal kits. Ford and GM vans have direct replacements.
A single fan unit could draw up to 400W of power at 12VDC. So, ensure you have a good battery and charging system. You should have this anyways.
Over in the Ram Truck threads, this is a common thing for them to do. It gains some Hp and fuel economy.

I live in Texas and prefer double row (Heavy Duty) radiators for all my vehicles. To me they are worth the extra cost.
Due to the fact yours has AC I would wire in a second input to turn the fan on when you have the AC on as well. This will help the AC system keep you cooler when in city stop and go traffic. By using some diodes you can have two separate inputs to signal the relay (one from the coolant temp sensor, and the other from the AC relay). The diodes would keep the temp sensor from back feeding the AC relay which would cause some problems.
