Rad Fan Thermo Switch

[Matt twentyV]

I'd go for the hotter range part.  Some writeup
on Scott M's page, he got better mileage with it than
with the colder part.
Both are available from TPC, and the switching temps
I listed are from their website.  Sometimes their
text descriptions are a little off so I would trust
the Bentley numbers.  Don't remember the cost
but can look it up tonite.. been a good 2-3 years
since I replaced mine.
