Modern Cooling System Design: It’s Not About Temperature; It’s About Powertrain

Reading engineering papers tends to be a boring exercise, but they do give a technician like myself a new perspective on how a common automotive cooling system could actually be improved. Of course, our immediate thought is how the cooling system can keep the engine cooler. Not so, according to one paper.

How Engine Coolant Temperature Sensors Influence The Modern Powertrain

  Considering that roughly 1,500 or more ­different vehicle models are introduced into our domestic market each year, it’s becoming more difficult to predict how a powertrain control module (PCM) will utilize data from a particular sensor or detect an out-of-range sensor in any single vehicle platform. The engine coolant temperature (ECT) ­sensor provides a
