Throughout the past winter, I received numerous phone calls from customers complaining that their engine preheater wasn't warming the oil.
In this video, I'll discuss the probable cause, conduct a test to determine how hot the preheater is actually warming the oil, show an example of an installation error, and address a few more concerns related to oil temperature.
Enjoy!
