Coolant after run pump

My coolant recently started going low. Noticed it in the past month. Today while changing oil I noticed coolant leaking from the belly cover. Looks like the pump located next to the crankcase is leaking.
How involved is it to change this?

Are you referring to the [Heater Support Pump] on the back of the engine? Or the pump on the side with the N489 Valve?

Look at page 22 of the Self Study document.

It is a pump that sits aft of the crankcase oil drain plug, about the same level as the plug, to the right of it. Directly above this pump is the right front axle. To this date I don't know how to upload pictures. Sorry. I looked at ECS and it might be the auxiliary fuel pump.
