Oil leaking from water pump tell, tell hose.

[gunslinger_006]

I had a small weep from the coolant drain bolt on the water pump after a recent 1000mi trip. Turned out i just needed to retorque the bolt and its good now. The copper washer wasnt perfecty seated i guess. I bought a few spares and will replace it next flush (i reused this one last time because parts were backordered).

In my case the dealer ended up replacing the entire pump, after the attempt on replacing just the seals.
My recommendation is forget about replacing the seals only, replace the whole pump. I have not had any leaks since.

Is there a trick to avoid doing a coolant flush ?

Depending on age and mileage, it's probably due for a flush anyway.

I just changed the coolant and I was hoping to avoid it. Not a huge deal either way, I just wanted to know if there is a way around it.

In the KTM world there is a way to get around just about every procedure in the book to save a minute or a buck.

I don't know in what way your trying to take a short cut but a coolant flush is just that a coolant flush.
You can doit or not, BUT
Glycol gets corrosive with use and age, especially on aluminum.

To “Avoid” changing the coolant, there is no procedure. With a refractometer, you can measure the "antifreeze" capacity of the coolant, but you will not be able to know in what condition the other additives (anticorrosives/lubricants) are, and if you were to take a sample and take it to a laboratory that would analyze it and conclude that the liquid it is turning acid, because the “other” additives are reduced…..where would you get only this additives?….so the best thing to “extend” the coolant changes, is to use those of the organic type, whose degradation is slower and allows you to double/triple the time of useful life, compared to an inorganic
