i still have stock ca thermostat and i want to make sure the engine warms up before fist fan comes on. what should i set 2nd fan to come on. i live in VA so summers do get hot.

the problem is i think i had them set too low so when i turned car off the fans stayed on longer than 2 minutes. they stay on for 6-8 minutes. the needle never goes past halfway on gauge either. i have new ecu temp sensor and gauge sensor too, just to cancel them out as problem.

idk i believe the fans stay on till core temp gets down to the turn on temp.

190 F is a good ballpark, then have them shut her off when it hits 170 or 180. Might keep them on a while though. Hell I have no idea. I just have a knob I turn to set the temp on mine. It gives me no precision at all.

its a tricky little bugger. so set first fan to come on @ 190 and maybe 2nd fan to come on @ 200?

I have a 180* thermostat and I set my fans to come on at 190*. They do run for a bit after the car is off, but I have a Yellow Top so I don't care.
