I've got the parts and the need to do this job. I'm going to Vermont and it's been well below zero there at night. I don't think that the cardboard in front of the radiator is going to cut it for this trip.
Thought I would just test my proceedure out here before I do something foolish. I intend to drain just enough (how will I know?) antifreeze out at the radiator into a clean container to remove and replace the thermostat. Replace the antifreeze fluid. Test drive.
Assumptions: I don't have to drain the whole system. I don't have to drain the antifreeze from the block drain. The antifreeze is fresh from this summers 210kmi maintance.
Anything I've missed. I mean besides the beer break.
