Coolant tank noise

[DWBOX2000]

I have a noise from the right rear side when moving over bumps. When the car warms up, noise seems to vanish. Is it possible the coolant reserve tank is loose. I can't think of anything that would expand? Maybe I will retorque. Anyone know the torque settings. Can't be much. Car is 2000 S.

Check to make sure that the coolant tank isn't cracked - very known issue because of its poor design. Link below to the replacement procedure if needed.
