Over heating 6V92

[Gregory OConnor]

Jay, maybe the bus was in drive with the e brake on?? I cant get
anything to warm up to 190 while idling. At days end as I park my
truck, I run the fan override to cool temps and turbo down. If I
forget to turn the override back to automatic, when I restart the
truck in the morning, the temp climbs up quick as the fan load is on
the engine at low RPM. The fan cools the radiator and only needs to
be on when the thermostats are open. Too often folks reengineer the
cooling by putting in low temp tstats which open prior to needed
optimal running temp.

Dirty Air filter can heat an engine up at idle. Low oil press will
cause heat (thus need for high idle). Pissy injectors don't burn and
cause a load at idle. Bad gauges re always a possibility.

I often wanted to record temps via a raytec laser gun at different
parts of the block and cooling system on the bus when it is run one
hour-- after idle-- after hill climb and high temp. This would help
pinpoint problem areas when an issue arises. It works good when
checking brakes hubs and other comparable moving parts. ( I'll check
the temps this weekend after I takes the Christmas lights down)

I found a green stain on my sight glass in the puke tank (pt40 '94)
and simply removed it to clean the glass. The green stain caused
false full reading.
