I've had the P112B, P2F22 pop up twice in the last 6 weeks, most recently yesterday. Driving home from work yesterday the temp warning light came on followed by CEL. Cleared codes, checked under hood and coolant reservoir is empty. Reviewing NAM, seems that I have a bad thermostat housing and probably thermostat. Car has 110k km....right around the 60k miles mark where the thermostat housing commonly fails.

I believe this is the part I need:
Part# 11-53-8-699-290

Question is: should I replace anything else?

Perhaps Water Pipe, 11-53-7-589-713?
