Question about Secondary Fan
#1
![Question](https://www.rx7club.com/images/icons/icon5.gif)
I have a question: generally when is the secondary fan suppose to kick in?
i have noticed that mine will only do it some times.
second question.
can i wire the fan to always be on when the car is on? i don't want any cooling issues. is that plausible? i have noticed my temp go up ever so slighly but im not hearing my fan come on when the at a light or even when the car is fully warmed up and i turn the engine off but the leave the key in the "on" position like it use to.![scratch](https://www.rx7club.com/images/smilies/scratchhead.gif)
thank you

Better description needed...unsure what a "secondary fan" is.
Running the fan straight off the ignition (i.e., "always on") is ridiculous and intentionally disables one major advantage the efan has over the stock thermoclutch.
My fan low speed triggers on at 195°...it hasn't come on since November.
Until ambient reaches @60° the car just doesn't require a fan.
I can't really tell when it does come on anyway. If it weren't for the temp gauge falling, I'd never know.

There should be a sensor with a pin pointing up near the thermostat housing. That's your fan switch. If it's working fine (FSM has test procedure of putting it in a pot of water with a thermometer), let it do its job and it will turn on the fan only if needed. I believe it should turn on the fan if you ground the wire to the sensor with ignition on, if the rest of the circuit is fine (relay, wiring, etc.).
No need to wire it constantly on as mentioned. And your terminology is correct. Not all cars had the secondary electric fan.
Is your temp. showing around half way at most?

when the Mazda thermostat opens, it also closes this port, aftermarket ones don't, and this lets the cooling water just circle around the engine instead of going through the radiator like we want it too

no. the reason we can't run aftermarket thermostats is that most engines have a thermostat bypass hose, to let the water pump pump water when the thermostat is closed, and the rotary has a port under the thermostat to do this.
