2001 Toyota Tacoma Radiator Radiator
The high-quality all-aluminum two-row Flex-A-Fit radiator with 1-inch tubes has internal fins that are designed to absorb more heat from the engine coolant, then radiate it though the external fins. This design offers excellent cooling and heat dissipation. It is available in three different core sizes to fit a variety of vehicles, including our beat-up Tacoma.

2001 Toyota Tacoma Radiator Electric Fans
I used the truck's existing Flex-a-lite electric fan on the new radiator since it was in perfect working order and covers almost all of the core for better cooling. It mounted neatly on the radiator with only some minor trimming around the upper and lower hose inlet and outlet.

2001 Toyota Tacoma Radiator Radiator Mounts
The factory radiator core support was beat up and damaged so I needed to fabricate some radiator mounts at Off Road Evolution. After I bolted the fan to the radiator, I dropped it in place to mock up some mounts. The Flex-A-Fit side-tank T-channel design makes a tough radiator swap a simple one. It was easy to make notched brackets, then weld them to the Tacoma's existing cage.

2001 Toyota Tacoma Radiator Mounting Brackets
I welded my custom lower radiator mounts directly to the frame. The fins make it easy to adjust the radiator for proper positioning and clearance tolerances. The radiators come with a bracket mounting kit, but due to this vehicle's front-end damage, I didn't want to take the chance of mounting the radiator to a weakened factory core support.

2001 Toyota Tacoma Radiator Variable Speed Fan Control
I also installed Flex-a-lite's new variable-speed-fan control module with a screw-in temperature sensor. This unit is simple to install and comes with complete, easy-to-following wiring instructions and a separate fuse. The unit allows the installation of on and off switches to control the fan during off-highway situations like water crossings.

2001 Toyota Tacoma Radiator Inline Temperature Sensor
This is the inline temperature sensor coupling. It's extremely easy to install and looks far more professional than units that shove a probe down the end of the radiator hose.
