Hi everyone,
Posting for some guidance and help today.
I turned off my e36 318is last night and heard a rattle/knocking from under the bonnet. I opened it and repeated. I've noticed my fan is somewhat smashed up, missing a lot of blades and also coming loose to the point you can see the ball bearings its mounted with.Ive included some pictures taken quickly with the iPhone below but I'm not sure if they'll help.
I don't know much about this area so I was wondering a few things:

1. Is there a quick fix to keep me on the road a few days longer?

2. I'm going to need to replace this fan, should I use this opportunity to switch to an electric fan?
If so, what components will I need and does anyone have any help or experience on the matter?

3. I was due a full service on the car including a thermostat change and more than likely a change in alternator and other belts etc. Is a 80C thermo worth doing or should I just stick the OE one, maybe in an aluminum housing?

For the moment its primarily the fan issue, I need to know what to do now and where to go in the next few days as it needs replacing.
Thanks in advance, all advice is greatly appreciated.

Chris
