Review on Derale 16822 Output Single Radiator by Daniel Russell

Fancy electric fan with 2 speeds. I'm convinced that any "less than outstanding" rating was probably installed by someone who doesn't understand 12V electronics and wiring. I used two 30 amp relays, one from the temp sensor and the other from the A/C trigger. Works beautifully and is much quieter than a factory mechanical fan. 2007 Toyota Tundra 5.7 V8
