Volvo 740 cruise control--how much vacuum does the pump supply?
The Volvo 740 typically uses a vacuum-operated cruise control system that relies on a vacuum pump to function effectively. The vacuum pump generally supplies around 15-20 inches of mercury (inHg) of vacuum pressure, which is sufficient to operate the cruise control actuator. It's important to ensure that the vacuum lines are intact and free of leaks for optimal performance. If you're experiencing issues, checking the vacuum levels and the condition of the pump can be a good starting point.
