what temp to set fans, please help
what temp to set fans, please help i know the stock fans come on around 225 and 235, but i want to lower that temp. what is a good temp for them to come on for a mostly stock car. i dont want it set too low so that it never warms up the car. thanks.
I dropped the stock fan settings 20*F on my '02 Z28 when I had it. That was with a stock t-stat. It helped to keep the car under 215*F while sitting around and less while moving.
The only downsides to fans on, are fan lifetime and a
tiny bit of fuel economy. If you have a radiator airflow
surplus then the thermostat is fully in charge and life
is good.
I set mine to something like 176/175 (low) and 180/179
(high) working with a thermostat (Hype-Tech "160")
that has a natural 177F pivot temp (seen by the logs
at highway cruise). So I run low speed fans pretty
much full time, the 'stat has a cool radiator tank for
backup most of the time and if that fails the high speed
comes on shortly after.
Stock I would recommend keeping the stock 'stat and
put the fans more like 195/193 and 200/198 (stock 'stat
pivots about 194). Raise the lower number some if low
speed fans bug you (my exhaust is loud enough that
they don't)/
