cooling question?
 

Have you guys heard of the parallel fan trick? You wire the fans to both come on instead of just one.

I have not done it, But They both come on with the AC on the stock car.

My question: Do you think it is worth it to turn on the AC in order to turn on both fans when the car starts to show higher temps?

You get more air but the motor is working even harder?

Seems to work for me in traffic, but not on the road?

So one way and the way I did this: Mod makes them both come on whenever the main (left - driverside) fan comes on in this scenario the A/C control has less effect on the fans. I believe the A/C may still turn on the A/C fan if the other fan is off otherwise engine fan is on = both fans on. This is how mine is wired now. Tip: if you're going to do this you can wire it in the engine bay not under the dash - unless that is you like being upside down ;-) just find the correct color wires and splice per whatever instructions you've dug up (Gary at trackdogracing will provide the diagram if needed).

Another question:
I have an aftermarket radiator and I flushed the system yesterday. It took 1.5 gallons of H20 and one bottle of Water Wetter, topped it off with antifreeze.

My capacity is just over 1.5 gallons. What is the stock miatas capacity?

less then 2 gallons i believe

1.6 is 6 liter(6.3 US Quarts)
