Thank you for this Rob, I've spent two afternoons trying to remove the steel coolant pipe and thermostat housing so that I can check and replace/reseat the seals as I have discovered a leak here at one side of the thermostat or the other.
Your guide has re-assured me that I'm following the correct procedure, as I've failed to remove the steel coolant pipes and thermostat so far. I guess I need more gorilla wrestling practice.
The time that you've put into the community over the years is always really appreciated.
