Coolant out the bottom weep hole

[D captain]

Hi everyone
My 2009 gen 2 with 67.000 kms just started puking coolant out the bottom weep hole. So from what I have seen online I guess it’s water pump replacement time. Since the water pump and oil pump are Connected together do I have to buy whole combo or is there a way to just replace the water pump itself? Curious is there any resource online in replacement of the pump ? Looks like exhaust and oil pan has to come off.

Not sure about the Gen 2, my Gen 1 started to weep and it just needed the Pump seal and a new impeller, the pump itself was fine.
