Hello everyone, just bought myself a 08 Hummer H3 176k and its awesome. When I bought it the dealer said that the only issue is the fan clutch? can be very loud for a few mins during driving. Then it's good. Should I be worried about this.

 

Change fan clutch then!
If fan is pulling air and cooling your radiator, you don't mind the noise and adds to HUMM, all is fine.
If temp gauge sits in middle, you are gold.

Of course, I don't know how long fan clutch will work and break down completely, can it break down catastrophically?


I spy with my little eye, that is an X trim, nice! Similar to mine

 

It is supposed to be loud when you first start and begin to drive. If that lasts more than a few minutes or miles, then it may be time to replace it.

 

"Free wheeling"
A fan clutch is a thermostatic engine cooling fan that can freewheel at low temperatures when cooling is not needed, allowing the engine to warm up faster, relieving unnecessary load on the engine. As temperatures increase, the clutch engages so that the fan is driven by engine power and moves air to cool the engine.

 

tha is for the advice, yes Xtrim is a beauty

 

did not know this, it only does last a few mins when driving. Gracias

 

wanted to say love the forum lots of info on here. My Hummer really is a great ride especially now with winter here.
