Water Pump Leaking Replacement Repair

CLAWHAMM3R · Nov 23, 2011

Hopefully the subject tags will make this easier for others to find in the future.

Anyway, my water pump is leaking, a lot. I got under the bike and ran it and it's coming out of the seam where the pump goes into the block. I assume that's the main seal?

Here's a pic to illustrate where it plugs into the block:

I searched on this issue and didn't find much on what it takes to replace or repair this. Anyone got any info on this? Obviously I have the FSM, just looking for any tips or tricks. I've done water pumps on cars before so I'm sure it's mostly the same.

Basically, if I buy a pump from someone's part out, do I need to go to the dealer and get o-ring X or seal Y or is this just plug and play and as long as the other pump doesn't suck, leaks be gone.

Anyone?

For an awesome story of how much my life sucks lol, read this: So I'm driving to work smelling something burning. I'm stopped at a light and smoke is coming out from under the hood, so I pull over and take a looksee and there's oil all over the place. Car is running fine, no lights or anything, so I limp her home to take my bike to work.

Get half way to work on the bike and look down at a light and the bike is pissing coolant all over the ground. So I get my roommate to drop off some coolant for me so I can fill it up and race home (vs. the leak) after work and as I'm walking out it's starting to rain! FML?

2 weeks ago I got a ticket, last week my phone died and then my cat broke his leg. W T F.

Yeah I know, cool story bro.

With that, you should check oil, as that seal that goes into the block is right there at the oil pan, and you could be getting coolant into you're oil. If that is not the case, and if you have the extra time and some spare change, replace the seals, and don't worry about a new pump. As long as it didn't run dry, you should be fine, pump wise. They operate the same way as a car, but they have way more for cooling, from the bracket by the throttle bodies to the oil cooler, to the coolant lines that run through you're oil pan, it has got them all!

Thanks for the info. I'll check my oil when I get home from work today and see if it's milky. The pump never ran dry and I never got close to overheating despite losing a large amount of coolant. So you think should just pop it out and put a new #11 on it and call it a day?

I like simple and cheap! Especially cause everything else has left me broke lol.

I would also get part #7 5 4 3 2 and rebuild the whole thing to be safe.

Yeah, check the oil, and make damn sure. Mine popped a seal a while back. Don't replace the housing and everything, they can be rebuilt, besides, would you want second hand crap on you're bike when it comes down to getting home without chernobyl happening under the seat?

Turns out it's coming out of the weep hole. On the hunt for a new pump. Don't feel like rebuilding.
