The unique part of Flex-a-lite radiators is the mounting brackets. You have almost limitless possibilities as far as elevation and how far back or forward it fits. We slid the bolts into place on both sides then used clamps to hold the radiator in place while we leveled it and set it in its prime position. The hoses were even trimmed and fit into place. The only thing we had to do was run to a nearby auto parts house to get a new thermostat housing where the inlet pointed to the driver side of the vehicle rather than straight forward. The same hose should work fine after a quick nip and tuck.

After we were satisfied with the radiator position, Harrison Ortis removed the radiator while it was still C-clamped to the support bracket and drilled holes for the bolts. All the brackets and bolts come in the box with the radiator- we put them to good use.

Now that the radiator had been bolted to the support, Harrison simply dropped it into place and bolted it back down. Now it's time to wire the electric fan.

All the wires, fuses and crimped ends are supplied with the fan. You should be well-stocked with what comes from the box.

Before wiring the thermometer/sensor, (which is already attached to the electronic control on the fan) it should be carefully slipped into place between the rows.

And lastly: The wiring and bench testing of the radiator. The wiring instructions are simple and easy to follow. The negative gets grounded. The positive gets wired to the battery, and another is wired to the ignition source. Flex-a-lite also offers an optional manual switch, which you can mount in the cab. We didn't opt for this, so we were done with the wiring. If you notice in the photo, there's a dial on top of the fan's electronic box. We boiled a cup of water and used a thermometer to measure the temp of the water. We then stuck the thermal probe into the heated water, then turned the dial left or right until the fan kicked on. Let's say the water temp in our cup read 190 degrees Fahrenheit. We turned the dial until the fan came on and made a mark on the dial. We knew this was 190 degrees F and that the fan would kick on every time the temp reached 190. Our only complaint about the fan setup is that there are no numbers on the dial. You have to set them yourself and measure when the fan kicks on and at what temperature, then make a mark for future reference. All in all, this radiator went rather quickly and we had no problems other than getting a new thermostat housing.

We didn't order our trans cooler from Flex-a-lite; we already had one from Gear Star Performance Transmission, which also supplied us with our transmission. All we had to do was extend the lines with these supplied hoses and mount the trans cooler in front of the radiator.
