We moved onto building some structure
to remotely mount our Stacked Plate fluid
cooler. Our plan is to mount the cooler in one
of the many open spots under the truck’s bed.
That should help keep it cool since there are
few other sources of heat under the bed (other
than the muffler), and this unit has its own fan
and thermostat to switch the fan on when the
ATF reaches a preset temperature.6
Our Extruded Tube Core Performance Radia-
tor s w ith integrated Flex-a - lite dual electric
fans comes with a Flex-a-lite Variable Speed
Controller (VSC), but little Redferd has its own
electric fan control built into the Summit EFI-
500 Throttle Body Fuel Injection. So we round-
ed up three 12-volt relays. Two of the relays will
run the fans on the radiator, while the third will
run the fan on our remotely mounted Stacked
Plate fluid cooler. Wiring up these relays is pret-
ty easy, and we did use the Maxi fuse that was
included with the Flex-a-lite radiator to protect
the three relays on the power supply side.7
We then mounted the relays and Maxi fuse
to Redferd’s inner fender and tied the sup-
ply side into the starter solenoid. The instruc-
tions that came with the EFI showed us how
to wire the two radiator fan relays so the com-
puter can control them via the ground terminal
of the two relays. The third relay is hot running
to the small integrated electric thermostat,
which turns the fan on and off when needed.8
Some folks don’t like self-tapping screws,
but we sure do. They are quick and easy
when mounting lightweight components like
this Flex-a-lite Stacked Plate fluid cooler we
w ill run in series of the low - pressure power
steering hose. On the other side we used a bit of
spare aluminum angle and some^1 ⁄ 4 -inch bolts
to secure the cooler ahead of the radiator.9
We mounted the remote Flex-a-lite Stacked
Plate fluid cooler with integrated fan and
thermostat under the bed just aft of the bed
on the passenger side. We may need to make5
