Coolant coming from weep hole

Coolant is coming from the weep hole when it is first started. I looked in the manual and it says to replace the water pump seal and tranny seal. Is this correct and if so how do I do this and should I also replace the impeller with the newer 06 model with hole in it and the shaft. I just got this bike so any help would be greatly appreciated. Thanks.

Do you have detailed instructions on how to do some or all of this?

Coolant is leaking from weep hole. I replaced both oil seals, gaskets (case and water pump) impeller shaft and bearings. Only thing I didnt replace was the impeller itself.

Coolant leaking from hole under water pump houseing


Coolant leaking from the "weep" hole indicates that the seals are out on the water pump. That's actually what the hole is for, to monitor the condition of the water pump seals. Pretty simple fix with the factory repair manual. Replace the impeller shaft and bearings along with the seals while your in there. Good luck!

When Ideling coolant drips underneath the water pump


Most Yamaha water pumps have a "weep hole" on the bottom of the water pump housiing.
Basically your water pump shaft has a coolant seal and an oil seal where it is driven...the weep hole drains away any leakage between the cooalnt and oil seals so cross contamination does not occur.
You probably should look at rebullding the pump. Don't try plugging off the weephole to stop the loss...it will contaminate the oil system.

2004 YZ 250 is leaking fluid out of the hole just behind water pump underneath the crankcase. The gasket looks fine and its not leaking from the gasket its actually coming out of the hole. I started...


The hole is a weep hole, designed to drain coolant from water pump seal leakage or oil from bearing seal leakage from contaminating either system. So one of the seals is leaking, and you should rebuild the pump.
Looking at the parts diagram it appears the impeller is threaded onto the shaft on the YZ250....hope that helps, heres the parts diagram

Anti freeze driping out of seep hole from the bottom of case


hello
there are two different seals on the water pump. the oil seal and the mechanical seal. the oil seal helps seal out the oil from the trans case. the mechanical seal helps seal the coolant from going into the trans case, and vise versa.
the weep hole is there to help diagnose if either seal is faulting. so if coolant is leaking from the weep hole. the mechanical seal is faulting or if the oil seal is leaking oil will drip from the weep hole.
hope this is of some help. thank you.
