Overheating question

[Brassman]

If you still have worries you could always do an oil analysis and see if you got metals in your oil. I would think a '71 series could handle a moderate overheat condition much better than a '92 series.

Before you do that, verify the accuracy of your temp gage. If the gage was reading 10 to 15 degrees too hot, then there isn't a problem, except for the gage.

Compare your dash gage with the one in your engine compartment.The one in back tends to be more accurate!!

I think every bus-nut should have a laser temp gun in their bus ($25 at Harbor Freight).  And I also think anyone that has a Detroit 2-stoke (etc.) should get get that laser temp gun and compare the temp at your engine sending unit to the dash temp gauge.  And I also think that when your engine reaches 200F you should pull over and analyze the situation.  I can also add that every bus that tends to overheat should have a radiator water SPRAYING system (not misters).  Follow the above and save your engine!
