Over heating 6V92

[Jerry]

How do you calibrate the RAYTEC heat (IR) detector? How do you correct for
the emissitivity of the item being measured? These items on early such IR
detectors could result in gross errors if not properly done.

Jay, if you turn on winter to cool it down, would you not also have
to run the fans over the various heat registers to have any cooling
effect?? I wonder if winter restricts flow dynamically to the engine
R in an attempt to bring the heat up at Idle as in winter ambient
would be lower?? Maybe that restriction (i.e., valve) is stuck or
the water pump or belt is bad?? Is it possible to eliminate the
chassis loop prior to any diverter valves, Manually?

As the engine is heating up, a Raytec laser would help detect extreme
heat if one piston or bearing is causing more friction then the
other. Use the raytec to check temps of cooling water ( early after
startup as temps on the cockpit gauge start to climb)to see if the
flow in to the Big Radiator is as hot as the flow out of the Engine.
if the temp into the Radiator is cooler your problem is flow ,
chances are the pump or belt or restriction is your problem ( bad
flow can be push problem or restriction problem). When a pump goes it
usually leaks unless some one put in the majic radiator stop leak.
Early on, check the temps in the radiator core. It should all be as
hot or hotter than the exit water. This would reveal a plugged core
( definitly a plug if a upper section is cooler then a lower
section), or just bad push from the pump.

I like your water radiator cool tip. Wonder if there was a way to
use the gray water. Use of the other tank contents would give
literal meaning to a offensive phrase, but may prove help full when
followed too closly by other motorists.
