| Re: Operating Temperatures Help - Installing New Temp Switches My signature shows 1991 advice for fan troubleshooting.
Buy the 200/185 fan switch. Works great in summer and winter. Doesn't run all the time, wearing out fan motors like the 177/165 fan switch does. It won't run in the summer unless you need it to. Probably won't run at all in the winter time.
195° thermostat? I wouldn't. 180° seems to work rather well for me. And I live in hot muggy Texas. My car really likes running at 180°. I used to drive my car in Canada with the 180 and even the 160. I preferred the 180 in both climates. Only benefit to 195 is a minor increase in fuel economy (about 0.5 mpg)
I prefer to not manually tie both fans to the same turn on point. The peak voltage requirement that that causes can be hard on electrical. Just get a different chip that turns your first fan (driver side) on earlier.
My cooling setup is rather simple, but effective. 180 stat, chip turns 1st fan on earlier (190/185), fan switch (200/185) for the 2nd fan. Keep the radiator clean and make sure the air dam is functional. |
