WATER LEAK AT SHAFT OF WATERPUMP , BIG JOB TO CHANGE PUMP ?

NO the leak is a clear indication that the water pump seal or the rubber bellows has failed and any stop seal will be moved out of the way by the action of the spinning shaft. Replacing the pump is the fix required.

Big job.. Strip to and remove all cam belt covers etc. then remove water pump and replace. Check out and replace belt and tensioners and idlers as required while there. Get a manual..

Unfortunatly its probably the front cover..The waterpump bolts go through it..Pretty big job ..You have to remove the waterpump and loseen the oil pan bolts to get it off.. if its the 3.0 engine

v6 or v8? v6 should take 2.2 hours, v8 should take only 2 hours to replace waterpump, replace coolant. water pump replacement is not an amateur job, please be careful ....

Sounds to me like the shaft seal has failed on your water pump and you need to replace the pump, theres usually a tiny hole either at the bottom of the water pump or at the top of the pump its called the weep hole, when coolant comes out of this hole it means the internal shaft seals of the pump have failed and it requires replacement of the pump, now if the coolant is coming out of where the pump bolts onto the engine block you propbably only need the waterpump to block gasket to fix the leak, check and see exactly where the coolant is coming out from so you can be sure exactly what you need to replace....

Have to look at the new pump,some are a splined shaft that just slides on to the gear ,those are fairly easy,if the new pump has a gear on the end the whole front cover and timing chain has to come off ,big job.

sounds like waterpump failure either the gasket seal or pump shaft seal

sounds like a bad waterpump. keep an eye on waterpump may be leaking. start there good luck.

behind timing cover, i believe it run by the timing belt. do timing belt when replacing waterpump, kind of a big job.

could be a leak or crack in a radiator hose
could be water pump not working good or leaking
could be radiator leaking
could be thermostat half blocked
