Ok, I pulled out my '03 wr450 a couple weeks ago to get ready for riding and, after dewinterizing and starting, water started leaking out the weeper hole in the water pump. So, of course I did a search and found all the info I needed to fix the problem. I replaced the two seals and the impeller shaft as recommended, flushed the system, and put in Enginge Ice for coolant. Started her up and after about three minutes of idling (to check the oil level) coolant starts spilling out the weeper hole worse than before. I decided the seal just might need a little running to get oriented and seal up so I took it up and down the street a bunch of times. No luck. So, I went and got another water seal and did it all over again. This time I carefully inspected the impeller shaft for any irregularites or burrs and made sure the bearing and both seals were seated properly. Again the leaking restarted after a few minutes idling. I drove it up and down the street a few times and it quit leaking. Went out for a ride the next day and noticed a few drops were coming out here and there, but nothing too big. The second trip out, the bike again started leaking pretty good for the first few minutes then slowed to just a few drips here and there. After 4-5 hours of riding I went through 3/4 of the fluid in my overflow tank. I would really like to quit buying Engine Ice at $16/half gallon. Any suggestions on how to fix the problem short of just plugging up the weeper hole?
