How do you know when it’s time to flush coolant? Technicians may have different views on the subject, but Dorman Training Center instructor Pete Meier explains how using a test strip at every service is a surefire way to get an accurate picture of the coolant’s health.
The following four vehicles (which certainly are varied) all came to me for repair and I did not identify the root of their problems immediately. And that’s because I was staying stuck in my ways and not adapting to changing vehicles. Let’s examine.
That’s four very disparate vehicles, no? But all of the problems listed had the same root cause: the battery was not up to snuff.
So now, when I have a diag to approach, I check the battery first. Some of you probably do this as well. Those who do not? Maybe give it a whirl. The following video explains it pretty succinctly:
Solid advice here. Those momentary voltage dips can cause all sorts of havoc, and the worst part is that havoc often looks very different than the problems we expect to see from a bad battery, like the traditional dim lights or sluggish starting.
Succeed where I have failed. Test the battery. Save some time.

Technicians discuss battery testing, one says open circuit voltage of less than 10.5 volts indicates a bad battery, while the other says that a reading of 12.5 volts indicates an 80% state of charge. Who is correct?
Is carb cleaner actually more dangerous than brake cleaner?
By breaking down the structures used to create DTCs, you can learn how to “decode” beyond the simple descriptions presented by a scanner.
It’s like torquing a bolt, but with an extra twist.
On a hybrid vehicle’s air conditioning system that utilizes a high voltage electrical compressor, can only the oil specified by the vehicle manufacturer be used in the compressor or is PAG oil acceptable for use in an electric vehicle’s compressor?
