Some time in the past 2-3 months, I started finding small amounts of coolant on the ground after parking the bike. We're talking about maybe a teaspoon, at most, directly below the weep tube coming off the front of the water pump (#11 in this diagram: 2007 Suzuki V-Strom (DL1000) WATER PUMP | PartsOutlaw.com
From what I've been reading, this means the seal (#3 in the water pump diagram linked above) needs replacement.
While I'm in there, I'm thinking I might as well rebuild the thing, replacing relatively cheap wear items like:
4 OIL SEAL, 09283-10005
6 BEARING, WATER PUMP, 09262-10016 (there are two of these, if I understand correctly)
and top it off with a new gasket:
5 O RING, 17435-02F00
and of course inspect the shaft of:
2 IMPELLER, 17491-16G00
for any scoring/advanced wear.
How long can I put this off? Since I need to drain the oil, I might as well coordinate the job with my next oil change, due in about 2000 miles (~32500 miles overall). I have a jug of Zerex Asian 50/50 standing by to top off the coolant reservoir whenever it gets low.
I have fresh tubes & seals for the rest of the cooling system standing by, just haven't done the work because nothing else is leaking (yet!) and everything but the radiator outlet hose (#3 from the radiator diagram Suzuki Motorcycle Parts 2007 DL1000 RADIATOR HOSE Diagram
) is kind of a pain to swap. I have a new #2 hose, pair of #9 O-rings, and #6 inlet connector hoses standing by as well, given those are all rubber items that are going to be degraded after 10 years. So, might as well do the whole job at once.
Do I have that right? Anything else I should replace, on the principle of it being a hassle to get to it again later?
Given the notoriously long lead time for ordering motorcycle parts, I better go ahead and put my order in soon.
