Question About Cooling
 

I Was Running My 86 Na For About 30 - 45 Minutes In Place The Other Day And I Noticed It Was Running Hot I'm Concerned What Would Cause This I Have A New Thermistat , Electric Fan Fresh Coolant At Proper Levels
What Could Be The Problem

the electric fan, the thermostat, etc

It could be a couple of things... for example how much CFM is the fan good for and is it wired correctly??? Or is it a new Mazda OEM thermostat (aftermarket thermostats fit, but don't work nearly as well as a Mazda OEM one- aftermarket thermostats almost always have cooling issues).

So yes, it could be your electric fan, could be your thermostat, could be a bunch of things

I don't know never had that unless the thermostat was bad.
try driving your car around .does it still run hot..
Is coolant comming out into your overflow tank?

my question is: what temp does your fan turn on at, if at all?
