Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Increasing Idle Speed To Improve Battery Charging
In order to drain as little energy as possible from the battery during freezing weather (below 34°F) the idling speed may be increased.
This ensures that the battery charge level is kept high. If the charge level falls below the calculated minimum level for starting, the idling speed is increased to 750 RPM.
The calculation of the minimum level for starting takes account of the temperature and the condition/age of the battery.
