To the general forum population: what's the best tool to use to get the fan bolt loose on an OM603, without having to remove the radiator? Sawed off Allen key, mini Allen socket, ?? I went to HF but they didn't seem to have anything that would work. It's an 8 mm, correct?

8mm hex key + 8mm deep socket + breaker bar + a bit of tape
Then switch to that hex key + box end spanner set up to do several revolutions.
just as depicted in that one thread to break the fan bolt loose. Getting it all the way out was the trick. No matter what tool you choose to use at some point before it is all the way out it will hit into the radiator.
I turned it out the last inch or so with my fingertips and got it started in like that too. Dont forget to clamp the fan pulley with some vise grips while you break the bolt loose. Helps to have a helper hold those vise grips in place while the other twerks.. i mean torques.
