Review on Dorman 621-300 Radiator Fan 🔥 Assembly: Controller-Free and Sleek Black Design by Terry Myers

Looks well built and breathable. In operation, it consumes just over 8 amps. The noise in the cabin is imperceptible, but of course you can hear it from the outside. The mounts are good and solid and the blades feel well balanced. I installed it on an older Tahoe that was struggling with our recent triple digit weather. Blows plenty of air to keep the engine within set temperature and cool the air conditioning even when it's been idling in triple digit temperatures for a long time. I hooked it up through a relay so it turns on when the AC compressor is running and so far it's working great. Use a 15A fuse to provide higher starting current.
