Coolant drain bolt

[Lonestar4x4]

I have a couple questions for the experts. I picked up a new 2011 250 six days and was going thru the PV adjustment (wasn't off by much at all). After putting everything back together I went to put the coolant drain bolt back in and while tightening to 9 Nm the fiber washer broke. My questions are; should I get another gasket type washer or should I get a copper washer? And is 9 Nm too much for the coolant drain bolt on the water pump housing? That seems like it may be too much and I'm paranoid I'm gonna strip the housing threads.

Thanks for any input!

9nm doesn't seem obnoxious. i use neoprene washers for coolant drain bolts usually a bag of 50 is only $5 or so...

I just snug it down with a nylon washer, which I found a lot of the correct size in work. Anything like this would be fine.

The fiber washers are crud. I had the same thing happen the first time I took it out. Doing it back up with hardly any force it fell apart. I went to the local hardware and grabbed a few small brass/copper washers. Cheap as chips and work good as gold.

Thanks guys! After doing a bit of work on this bike I now understand what everyone is talking about when they say "assortment of fasteners"... I'm gonna make a list this weekend of bolts to replace and nut rivets and nut inserts to buy.
