[TR] TR4A - Fan temperature threshold question

[Terry Geiger]

I like to use an adjustable unit.  The Derale 16749 uses a screw in sensor
and the Derale 16759 has a sensor that pushes into the radiator fins.

Subject: [TR] TR4A - Fan temperature threshold question

All,

What temperature is too hot for the TR4A engine?
I am looking to install a thermostatic switch for the electric fan in the
near future, but don't have any appreciation on the on/off temperatures to
look for.

I found an in-line switch from Derale that turns on at 180, and off at 165,
but don't know if those thresholds would be appropriate.

Thanks in advance.



Cheers,
