a hard time believing that the factory didnt supply a system that will operate correctly with full power at 90 degrees. in fact i would think that they would have tested it to operate correctly at at least 100 degrees.

i think it is not logical to think otherwise.

these cars are twenty years old. are you saying that everrthing is perfect in them? it seems a stretch to me.

i still say the cutout feature that you mention is for system malfunctions rather than a designed feature to compensate for a cooling system that won't operate correctly at 90 degrees.

if you were talking about gm not mb i might agree.
