Leak from pipe on the back of the water pump
 

Hello folks,

I have a leak from the small pipe on the back of the water pump, visible from the top standing and looking over the motor. Done a lot of reading and research, and need some reaffirmation that the part I need is in the link below...is it called the heater return pipe or transfer pipe?

Anyone else done this?

Here's the image from RealOEM - so is it part #1 or #4?

The thread you linked to is about replacing #1, as are some of the links to the parts...

#4

Seems like I should be able to just replace the O ring

Updating for future researchers

I replaced the O ring (part #5 as pictured above) and the leak is sealed, there was no need to replace the pipe, saved a lot of time and money. Don't forget to buy a water pump gasket, or replace the water pump all together if you haven't yet when doing this job (mine's fairly new so there was no need)

Great job - glad it turned to be cheap/simple - ideal! :thumbup:
