The seal between the impeller shaft and the housingwears out.
Time for replacement,
Bad seal or bearing
A leaking water pump means the pump needs replacing or the gasket is leaking. Either way the pump must be removed. Now if the hoses going to the pump are leaking, they either need tightening or replacing. So it depends on exactly where the leak is.
can you fix a leaking car water pump Yes you can fix it..If the water pump gasket is leaking then remove the pump and replace the gasket,if the pump itself is leaking from either a crack in the housing or from around the pumps shaft then remove and replace the pump with a new one... Fixing the pump itself is not something that is easly done by the average person....if the leak is from a crack in the water pumps housing then each end of the crack must be drilled to stop it from progressing any farther,then the entire crack must be welded,soildered,brazed ect depending on what type of metal the pump is made from... If the pump is leaking from around the shaft then the impeller and shaft must be removed and the bushings,bearings and seals replaced..this requires the use of a bearing press...
yes, leaking coolant is what happens before the pump totally dies, then you have overheating and possible engine damage soon after the leaking.
to change the water pump loosen all the pulley bolts, then take the belt off. after you get the pulley comletely off, there will be 5 more bolts. take them off and the water pump will come off. you might have to tap alittle.
More than likely a head gasket.
Water pump shaft loose? Water pump leaking? Water circulating in coolant system?
