Review on IRONTEK Cadillac Chevrolet Oldsmobile Radiator by Travis Flores

Doesn't work as it should. On a cold start it is fully engaged. After about 1/4 mile it cuts off like it should. As soon as the engine has reached its normal operating temperature, it starts again completely and never stops again. The constant roar of the fan is deafening. I'm losing almost all of the engine power to the wheels, and fuel economy has gone from 19mpg to about 8mpg. It should turn off as the RPM increases, but it doesn't. If you're even considering buying this fan clutch, look elsewhere.
