Diagnosing Intelligent Cooling Systems

The majority of cooling systems on the roads react to what is happening inside the combustion chamber. After the engine is stressed, the heat causes the thermostat to open. Increases in temperatures will also cause the cooling fans to come on. The heat carried by the coolant is the trigger for operation of the fans and thermostat.

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

Given the advanced state of internal combustion engine technology, some recent cooling system innovations will actually increase engine torque and fuel economy while reducing exhaust emissions. Let me simplify that idea: new cooling system technology will make engines run better and cleaner. So, let’s get on the same page by reviewing some basics.
