Thanks everyone, wasn't easy to get to, have replaced it. I need to also replace the Lower part of the plenum due to the inlet corroded aswell having trouble finding the part.

Hello im currently servicing my r33 due to knowing previous owner using no coolant and using purely water. Noticed all piping and thermostat housing all corroded. Anyone have info or a tutorial on removing the housing. Have removed radiator and hoses, all cooling pipes. Unclipped sensors. Would I need to remove plenum cover to access the part or would it be easy to access it via the three bolts underneath housing. my first time so yeah.... all comments appreciated thankyou

Do you still have the power steering pump? And also would you have the thermostat housing disconnected?
