VIDEO: Electronic Thermostats
Andrew Markel explains how electronic thermostats can increase efficiency and decrease emissions through controlled heating.
Diagnosing Electronically Controlled Thermostats
On these systems, there are two ways the engine management module knows there is a problem.
Servicing Electronically Controlled Thermostats
When the heater circuit fails, most of the time it will create an open circuit.

The Engine Thermostat: Understanding Electronically Assisted Thermostats
The engine thermostat has been an important component in automotive internal combustion engines for almost a century. The engine thermostat helps to speed warmup and reduce cylinder ring wear. Today, the engine thermostat plays an important role in increasing engine combustion efficiency and reducing emissions. To accomplish that task, engine thermostat functions are controlled by the engine’s electronic control unit (ECU), ensuring precise regulation of temperature based on the engine’s loads.
Automotive Thermostats Through the Years
They still have wax, but today’s thermostats use electronics to deliver precise temperature control.
Cooling System Leak Testing
What replaces the conventional water pump and thermostat is electronic thermostats and electric water pumps.Â
Diagnosing Intelligent Cooling Systems
You might be seeing a trend on late-model water pumps, such that an undersized mechanical pump being augmented by an electric pump with an electronic thermostat.
Solving Intermittent Overheating
New cooling systems anticipate and influence changes in coolant temperature.Â
Intelligent Cooling Systems
A conventional thermostat and water pump are similar to a carburetor and mechanical fuel pump in one regard – they can only respond to change, not be proactive in their engine management.
