well whats funny about this is you can set aem up to control your fans based on water temp. so that mechanical switch is not needed when aem is setup to control the fans.
i set mine to just be on al the time, but you can pick temps that they are on and off at.
stock ecu though must use this mechanical switch. makes sense, this must be wy people buy lower fan switches.

I personally wouldn't leave the fans on all the time, it's not really necessary.
Well technically, the AEM EMS / stock ecu / whatever all use the stock fan switch. It's just that with the EMS you can change how it operates bypassing the mechanical portion of the system.

I had this problem and solved it simply.
I had the car stone cold.
I took the bleeder valve out and attached a transparent tube.
I then blew into the radiator cap and watched the bubbles come out of the transparent tube - all was well but don't swallow any coolant.
In the UK we dont have a bleed valve on the heater system, just one bleed valve.

I was under the impression that the fan switch requires hot fluid for it work. But I could be wrong. Can someone verify this?
when your aem though, you can change it and control the fans thru aempro. thus eliminating the reason to buy lower temp fan switch since you can just say turn on sooner.

stock ecu and aem wihtout changing the tables both rely on that mechanical switch to get hot enough and activate the fans.

Let me clear it up a bit. Will the mechanical sensor trigger with only hot air or does it have to have liquid for it to read/trigger. If you have air in the system the sensor wont read/trigger or will it?

Yea I understand that part.

the motor overheats and the heater never blows hot cuase the fluid never moves thru the motor. it just sits since theres air in the system.

oh lol. the way i understand it, if theres air in the system, then the fluid doesnt move, and if it doesnt move, radiator never gets hot since the fluid in it just stays cool from air moving thru it. fan switch is mounted in bottom of rad i think, so it never gets hot enough to trigger fans.

That's also why the fans never turn on, if the thermo isn't circulating water, hot water doesn't flow through the radiator and thus doesn't trigger the fan switch to switch the fans on.
