Engine Temperature

The ECT tells the computer what the engine temperature is so that optimum driveability is realized while the engine is warming up and when the engine has reached operating temperature.

In "B.C." days (Before Computers), cold engine performance was under the control of an automatic choke whose adjustment was critical. Even when properly adjusted, the engine had to warm up before the car would perform properly. Often the engine had to be run at high rpm at idle just to keep it running when very cold. Then the engine would stumble and hesitate until it got warm.

Once the engine reached operating temperature, all we worried about was overheating. Who would have thought then that computers would someday control engine performance through all stages of engine temperature, maintaining good fuel economy, low emissions and smooth performance?

During cold engine run, the PCM would retard spark timing and run the engine's fuel mixture a little richer to help compensate for cold driveability conditions so characteristic of a typical gasoline engine.

A Wolverine Engine Oil Heater will heat up and thin out your oil for quick starts in cold weather reducing wear and tear on the engine thus eliminating worrisome engine temperature problems.
