The fan took out a few other parts with it. The belt sensor and the ac belt were destroyed too.

I am in a quandary over oem vs genuine. I know the difference, but what I dont know is if there is a difference in quality or is it just branding for Porsche. Are the genuine parts tested or quality verified in any way? In particular I am bothered by getting an oem vs genuine fan. I dont want it to fail again, but perhaps I am safe given that the one I do have lasted ~19 years but only 70000kms before failing.

As well I am unsure about doing the tsb. From what I could tell the belts were not squealing or jumping off the pulley.

Thanks for your support.

Regardless of which fan you end up getting, try not to let this incident throw you off your new 993 experience. They're great cars.

Hey Karl,

Before you order the extra parts let me just check what I have lying around. I know I have a belt sensor that is has less that 2000km on it. I may also have a new A/C belt as well. (i took my a/c off many years ago).

Here are some pics of the broken bits.

Looks like it took a chunk out of your table when it let go as well

Bummer about the collateral damage. Chances are you can get Porsche branded for close to OEM cost... Just checked, Sonnen website is back and their price is good $411, Sunset is probably close too.

That is a NICE piece of wood you're using for a table.

That's quite the collection of shrapnel!! Have Andreas make you a clock out of the old one!

Before you buy any parts from another parts supplier, get a price quote from Sunset Porsche.

Trust me and request the price quote.

By all means, do as Vandit suggests, Sunset is often the best price going. However, be sure to specify price WITH SHIPPING, using the shipping method you want; cheapest is UPS Standard but then on top of that UPS charges brokerage fees ($54.35 for value between $350 - $500) plus $4.25 COD fee, see:

Then do the same for Sonnen and FedEx. Last May fedex charged me $10 to import $357 in parts from Sonnen. You'll find that in Canada, you can't always shop in the USA by item price alone, a fact those living south of the 49th parallel naturally wouldn't know about.

Alternately, you can act as your own customs broker to clear your shipment, but you'll spend a couple of hours of your life (that you won't get back) at CBSA in northeast Calgary to sort that out.

Whatever you decide to do, the folks at Sunset, Pelican, and Sonnen all have always been excellent in my experience.

You guys have been great. Thanks for your support.

I just did a more thorough damage inspection and noticed that the crank pulley got deformed enough that it will likely destroy the belt after a few hundred miles.

Is it possible to remove the crank pulley without removing the engine carrier?

Karl

bcameron59

Yes, it's a tad tight but certainly do-able, in fact necessary if the pulley shims need adjustment to properly tension the belts.

But probably easier if you remove the whole fan assembly to replace the fan, and do the pulley replacement at the same time.

knorrena

Brian,

I am not sure I am following you. I am talking about the pulley mounted to the crankshaft. It now has a dent in it. Do you mean that getting at the crankshaft pulley is easier with the fan removed?

Karl

Sorry, had a brainfart and read that wrong.

The nut on the crank pulley is usually hella tight, will need a big wrench in there but you're right there's not much working room. Not sure a torque wrench will fit, might need a box wrench. It will be hard to undo, will probably need an extension.

bcameron59

Just had a look, box wrench won't get in deep enough. But it was possible to get a shallow socket (19mm IIRC) onto the bolt head. I don't own a breaker bar, but am pretty sure one could be fitted into the drive end of the socket.

Torque spec for this bolt is 170Nm, and it seemed like it was even tighter when I had to undo mine. Car will need to be in gear and brakes on to undo it. I wouldn't go any smaller than 1/2" drive socket and breaker bar for this.

bcameron59

Oh, just one more thing... (I'm chanelling Columbo today :-)

To ensure full disclosure, note than some recommend against using the brake / transmission method to break the crank bolt loose, and advise using a special Porsche tool instead - see this thread:

Now, Stephen strikes me as the kind of guy who just might have this exact tool so you might be in luck. Though it would be a miracle if he could actually find it in his garage, the place is way too tidy.
