Ok so I have a 84 GL Wagon, standard tranny. I have read to use a 180 degree thermostat but wanted a second opinion. Also, the sensor that controls the electric fan -commonly called the thermo switch or fan switch- may need to be replaced and i was wondering if i could get a lower temp switch so the fan would turn on before the engine gets super hot. This way it can start cooling down before its so hot that it will take forever to cool. Opinions? thoughts?
