Radiator Fan

Post by BC-Astro »

Hi Guys,

My radiator fan is blowing continuously - even with a cold engine ...
I assume this is not normal because it is too cold outside!

Anny suggestions to fix this `problemo`are very welcome =D>

Thank You,

Hello neighbour.

The radiator fan clutch has a fluid coupling. When you start up the motor in the morning, the fan will blow constantly for a few minutes until the fluid warms up and migrates through all the passages. This is normal. However, it is possible for it to seize after time. If it continues to blow throughout the day, then you need to replace the clutch.

Got any photos of your ride?

There is enough resistance in the fluid that the fan will always spin, even if the engine is cold. It shouldn't be blowing like a wind tunnel fan though unless the engine is good and hot.
