hmmm ok, why is it in there to begin with? just to drive the fan?

Some folk remove the viscous clutch and fan assembly and run an electric fan instead. I was tempted to do this but wanted a really well-sorted solution with a fully variable speed fan (not just a simple one or two speed arrangement) and the costs get silly really quickly when you go down this path. In the end I got a new OEM viscous clutch for around NZ$200 and so went with this. I guess in your case, there's a LOT more to replace...

ahhh ok, thanks for the info, makes sense now. Maybe the fan self destructed from high RPM, though that seems strange. I gues a new radiator and shroud make this repair a bit costlier.... hope nothing else got shredded in the process!

When the viscous clutch goes bad and locks up as wpoll points out, and the fan will run at full speed and make a jet engine sound at higher RPMs. Did you hear any strange rotational noises at higher RPMs coming from the engine bay?
I really should replace mine, I'm sure it's original.

well, when cold there was a bit of a wooshy noise from the engine for about a minute max before it went away, I figured it was a fan on high during startup but didn't know about the viscous clutch or it's explosive properties
The mechanic is ordering parts right now... lets see if I can eat a hot meal this month hahaha |

Haha, no, you are safe there. They just end up failing and you will get a code for the SAP.

Many times clutch fan performance will degrade over time, not just fail all at once. When it loses significant cooling capability the electric pusher fan will run more. It is intended to be supplement cooling, like when the AC is on, not as a primary cooling source.
A decent electric fan can be set to start up based on radiator temp. They have a dial to change the setting where you choose. I have it set to come on just before the front electric pusher fan engages. Have been running the electric fan in place of the clutch fan for several years, very reliable. Cost is reasonable. I did have to replace the controller once but it was not expensive at all. Replacing the clutch fan with an electric fan extends the life of the fan in front of the radiator and reduces heat sink as you can wire it to run after the key is removed, until the radiator reaches your setting where it turns off. Frees up a little HP/TQ but stating how much will start an argument. I have been using electric fans for decades on modded cars. Simple install, simple tools any DIYer will have. Doesn't cause any error codes. Not pitching electric fans, just informational. Clutch fans have been around over 50 years. They work fine and last a long time.
