Water Pipe O-Ring Replacement(Thermostat Side)

[95AWD6Bolt]

I just finished installing my PTE 50 trim turbo. I had to dent the water pipe to enable the turbo to snugly fit. In doing so, I think that I unseated the O-Ring in the water pipe on the thermostat side as it is now leaking on that side when I put coolant in.
My question is if I have to remove the entire pipe, turbo and manifold to replace the O-Ring? Or can I just remove the part that the pipe is connected to on the thermostat side and save myself a ton of time?

You only have to remove the thermostat housing, slip the new O-ring on, and reinstall the housing.
