20 hours later, the rounded bolt still clings on

In order to get to the water pump on the 280CE, the fan assembly had to be removed, which is held on by four rather inaccessible bolts.

Two of he bolts came out ok, but two were stuck firmly and became even more rounded in trying to remove them.   Mercedes must have used high quality bolts, as 20 hours and 5 drill bits later, the bolts are still in.

This is the frustrating side of classic ownership, an otherwise simple task becoming bigger than ben-hur due to a single recalcitrant bolt.
