Steeveedee,
Let me ask you something. Are you using a cell phone to view this site? If so, it might be difficult to see all of the posts. I don't think cell phones are cut out for much internet viewing.
Oh? Do not drill into the engine itself? Thanks!
Good idea about drilling into the thermostat, I would not have thought about that.
Dad has suggested I replace that before going much further also (original owner).
Oh no, I wouldn't poor antifreeze onto the garage floor, I don't spill things on purpose.
