How To Choose an Electric Radiator Fan

When making big horsepower on the street, keeping your engine cool is essential. Sitting in heavy traffic with a high horsepower engine, a mechanical fan just won’t cut it. Mechanical fans rely on engine rpm and when sitting at idle, they just don’t spin fast enough to keep your engine cool. Mechanical fans also rob your engine of horsepower and fuel economy since they are driven off the crankshaft. They simply can’t compete with electrical fans when it comes to efficiency. A radiator only works if there is airflow through the radiator core. An electrical fan provides constant airflow even when the engine is idling, when your engine needs it the most and since they are electric, they do not affect engine horsepower or fuel economy.

Whats the best fan for a LS6 since my 05 cts-v runs hot and I kust replace my radiator to a dewitt high performance radiator

[m.pietro]

Good guidance, however he said electric fan does steal horsepower from the engine, however the extra load on the alternator robs a lot of power.

Hey, I hope you can help or advise me. I have a Mitsubishi Montero sport 2.5 diesel(also known as shogun, pajero etc), and it overheat in uphills and slow traffic (my city is hot as hell, close to 40°C degrees often). In highway at high speeds it works perfectly. I already checked the whole cooling system (clean radiator, new thermostat, fan clutch is ok, heavy duty coolant, even new cylinder head), but it still overheat. I thought to add an auxiliar fan. However I don't have enough room to add it at the front, because there's a AC condenser and then an oil radiator (or transmission cooler more to the front idk). Do you think if a double straight blade fan would work installed at the front of the oil radiator? I dont know what to do 😑. Greetings from Chile!

Do I use my old shroud with my new electric fan?
