Keep the crud out of the weep hole
Haskell in Idaho told me about this fix he made for his 09 570 to keep the junk out of the weep hole, and the water pump shaft area. Anyone who has replaced their water pump seal on the 09 on up bikes has probably found a good deal of grit in the area between the water pump seal and the engine oil seal.
The weep hole is at 3 'o clock, so anything that get's in there can't just fall out. And to make matters worse, the weep hole points forward, so when riding through a stream or mud, it naturally ends up on the weep hole and then ends up down inside between the seals.
Haskell recommended that I just get a piece of 1/8th" tubing from the home improvement cent, cut it to length, put a dab of epoxy, I used JB weld steel, on the tube and gently tap it in the weep hole and then attach a short piece of tubing to it and secure with a small piece of safety wire to keep the crud out, yet you can still see if you are losing a seal. You do have to pull the water pump housing off to get to it, but the juice is worth the squeeze!
