The Nissan Path

Lately I’ve noticed that my mechanical fan clutch appears to be stuck , meaning every time I pull away from a stop sign or red lights the viscous fan roars. Originally it only did it on initial cold start ups. But now it seems to always be engaged. My MPG has also been reduced to around 14mpg but other factors could be playing into that.

MPG seems to fine when driving with little to no stop to traffic. Around 22MPG.

Give it a spin when cold and then again warm. There should be a large difference in resistance, it should be much stiffer when warm. If it isn't, or if it's stuck solid, then it's time for a new clutch.

Ok thanks.

My redneck test for this was to grab a small towel and see if i could stop the fan from spinning when warm... I supposed turning the engine off after warming it up is a little safer.

In some countries they cut hands off for stealing. Here only our vehicles do it.

It was a plastic fan so… probably not that dangerous.

Paper can cut you. Once as child, following a Florida hurricane, I found a blade of sawgrass stuck clean through the side of a telephone pole outside my grandpa's house. Almost anything moving can make a mess, it all depends on angle and speed.
