    Can any one tell me is it normal and i’m guessing NO that my klx450 weeps out the weep hole under my water pump only when it’s getting a thrashing.

    I have just put a new waterpump seal in and replaced fluid with engine ice.

    No mate if its coming out the weep hole, the weep hole is there to tell you the water pump seal is leaking. If it wasn’t for the weep hole the coolant would get passed the water pump drive oil seal and get into the engine oil.

    Sorry sounds as the the water pump seal job wasn’t done correctly or there is another problem in the water pump area but normally its the seal

    What was the shaft like if it has a few ks on it there could be a grove cut in to it from the seals and the new ones wont get to seal on it tightly so under load/pressure it will weep some coolant out

    check your coolant for foaming by shakeing some in a clear bottle

    Nothing as far as leaking from the seal goes, thats just a whole other thing :P Just fix the leak before you worry about that :laugh:

    Bulls right as far as the wear in the water pump shaft goes or in maybe not fitted square in the housing etc.

    Foaming coolant will cause severe cavation in and around the impella and cause a stall in the flow of coolant and this makes the impella hammer around and load the seal bearings of the water pump :S

    Yeah it could, But really Bull shouldnt we cover the simple things first, someone just had the water pump apart, I mean have you heard of many late model KLX 450’s with the above problem I dont think he should worry about that yet, I mean there are so many different things to get out of the way before he gets to the above isnt there including the pump thats leaking that someone had apart

    Sure but he also changed coolant so maybe try just water and its cheeper to use till the problem is found but like i said in my pm to Corey8 i am happy to look at it for him if he is close to Port and check seals and shafts ect

    Hey Corey,the spring side of the seal should be on the water side of the pump.
