Car Radiator Fan Amperage

Amperage used to measure how much load an electrical device draws when in operation.

Car radiator fan amperage.

Using a 30 amp fuse. Maradyne fans have motors that range from 130 to 225 watts. But 10 13 amps sounds about right. Motor power determines the amount of cubic feet per minute cfm of air a fan delivers.

Depending on the application it may freewheel above 2 500 to 3 000 rpm. A centrifugal valve opens to allow the flow of heavy silicone fluid locking the fan blades to the pulley. If you plan to upgrade your engine it won t hurt to install a more powerful fan now you can control its airflow with a temperature sending unit. My intrepid fans pulled right at 10 amps while running.

If you are worried hook it up to a 10 amp fuse turn it on if it blows well you know the answer. See all 8 photos. At idle and low engine speeds this fan clutch is fully engaged gradually disengaging as engine speed increases. Automotive fans are rated at 13 5 volts and the rating is after the motor is at operating rpm.

The initial start up of the fan will have an amperage spike of up to 60 percent which lasts only a millisecond.
