Engine Operating Temperature

From JeepForum.com Community Jeep Wiki

Page created for engine temp and discussion

"Many mistakingly think that all there is to decreasing temperature of the engine is to decrease the temperature rating of the thermostat. If the cooling system cannot keep up with the heat the engine is generating, a cooler thermostat will help precious little. The second misconception that if some engine cooling is good, more must be better. Again, most engines run optimally at the recommended factory temperatures. Significant departures from these recommendations are most often counterproductive. The temperature is critical to the efficiency of the burn of the fuel and the tolerances of the motor itself. 180-195 degrees F is common on conventional engines. Modern motors see higher temperatures (205-210F) , mostly due to fuel and emissions efficacy." Thats a quote from this web page, http://www.novak-adapt.com/knowledge/cooling.htm Hope this helps.
