Hi,

I'm overhauling the cooling system on my dad's CLK430 at 167K miles.

To remove the fan/clutch from the water pump, which way should I be spinning the 36 mm nut with the thin/flat wrench? If I'm standing in front of the car, should it be counterclockwise (to my left) or clockwise (to my right)?

Thanks for any guidance!

It's a right hand thread and you do have the tools correct!

Thanks. So if I'm standing in front of the car, I would turn the 36 mm nut counterclockwise to loosen.

I ordered this set from Amazon - hopefully it's of reasonable quality:

The tool kit is correct---regarding RH and LH threads learn something and google, there are millions of you tube HS describing the threads

Thanks Plutoe. A shop I spoke with last week said the 36" nut was reverse threaded (which to me means one would turn it clockwise to loosen it) but a couple of videos I had watched showed the nut coming off by spinning it to the left (counterclockwise), the conventional way (right-hand thread). That's why I wanted to confirm.

The tool set has arrived and i will attempt taking the fan/clutch off later today. I might douse it with PB Blaster first and let it sit for an hour, in case that's the original nut and it's frozen on there.
