Re: alfa-digest V7 #51RE: Overheating coolant

[FERDINANDO DI MATTEO <fredalfa@xxxxxxxxxxxxxx>]

I'm surprised at how many of you have no idea what the purpose of the
coolant thermostat is.  Reasons for overheating are many and guessing
solved nothing.  I shall try to tell you what I've learned about the
thermostat.  It is there to regulate the flow of coolant through the
engine and radiator.  If the coolant flows too fast through the
radiator, it cannot lose enough heat before it gets heated some more
with each pass.  An engine, any engine, depending on a radiator to cool
its coolant will overheat very badly with thermostat removed.

Thermostats can easily be tested and if proven to function properly, an
abnormal condition must be found elsewhere.  Fred Di Matteo  AROC Tech
