Good article. Accurate and safe.

Here are some additional tips that I was taught about this.

Step seven: I've memorized the phrase "Heavy, unpainted metal engine part 1 to 2 feet from the battery." I find that "non-car" people understand it faster like that.

Step 11: Ideally the car should run for at least 15-30 minutes with a good portion of that time having the engine above idle speed.

thank you. very accurate and safe. With the last comment, you can post this in a car manual.
