Car radiator fan amperage.

A centrifugal valve opens to allow the flow of heavy silicone fluid locking the fan blades to the pulley. But 10 13 amps sounds about right. If you are worried hook it up to a 10 amp fuse turn it on if it blows well you know the answer. Maradyne fans have motors that range from 130 to 225 watts.

Automotive fans are rated at 13 5 volts and the rating is after the motor is at operating rpm. Using a 30 amp fuse. 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. Amperage used to measure how much load an electrical device draws when in operation.

The initial start up of the fan will have an amperage spike of up to 60 percent which lasts only a millisecond. At idle and low engine speeds this fan clutch is fully engaged gradually disengaging as engine speed increases. If you ve got an electric cooling fan on your classic car or hot rod and you want to know how to wire it with a relay you ve come to the right place.
