Good catch MB Doc!

MW, he obviously knows by experience (and by the threads posted here) that this 'reverse' flow seems to be a a regular event.

One easy thing you can do is to ensure that your af/water ratio is 50/50%. If you live in a real hot climate, then 40/60 would be better. Of course, use only distilled water.

You'd be surprised to see that most af/water ratios are 70/30. That's enough to cause a elevated engine temperature. A simple af tester described in Menu#17 will ensure that your af/water is correct and your engine is properly cooled.
