Re: Anybody converting mechanical fan to electric on their RE?
I put in 3 junkyard fans on a 366 tall deck gasser. Using 2 adjustable electric thermostats for the fans, one set for about 185 degrees controls the 2 smaller fans on one side(a turbo saab fan and a toyota 4 cyl fan). The other thermostat about 190 degrees controls the big taurus fan. I now have good fan coverage of the radiator, and each shroud was custom fitted to seal right up against the radiator.
The initial test was done with only 2 fans, and I did not get enough cooling on a hot day going up hills. So I added the 3rd fan, and have not tested it yet.
If driving up hills is still a challenge, I will install 2 hi-flow coolant thermostats (mr gasket fits a chevy). A 366 tall deck uses 2 coolant thermostats for increased flow, but in theory the hi-flow units should provide even more coolant flow through the radiator. For $18 for 2 thermostats, it is worth a try. Anything you can do to increase flow through the radiator will result in better cooling. Ditto for increased air flow through radiator.
If the 2 hiflow thermostats still do not help enuf, I may install a windshield wiper squirter in front of the radiator and plumb it to my 50 gal water tank, with a switch, for the big hills, and also cut out a little sheet metal on the front grill for better airflow. Maybe even install some side body vents to vent hot air from the engine bay.
My stock fan was a 5 blade, 22.5" dia, high pitch fan with no clutch!!! Radiator is a copper 3 core. My guess is the electronic set up might be good for 10 ft lbs of torque, as the stock set up had a huge, constant drive fan.
