Frequently Asked Questions (FAQs)
1. What is the ported vacuum switch for?
The ported vacuum switch is used in automobiles to regulate engine vacuum flow. Before the advent of engine control unit computers, vacuum switches were employed for various functions. For example, a dual port vacuum switch located in the intake manifold monitored coolant temperature in the coolant crossover.
2. What are two types of vacuum switches?
There are two types of vacuum switches: electro-mechanical and solid-state switches. These switches differ in their construction and operation.
3. What does a vacuum switch do on a car?
In a car, a vacuum switch plays a role in controlling the flow of coolant to the heater core for heating the cabin air or defroster air. When you turn on the heat or defrost, the vacuum switch signals the coolant vacuum valve switch to open, allowing hot coolant to reach the heater core. If the coolant vacuum valve switch malfunctions, warm air may not be delivered.
4. How does vacuum affect engine performance?
Vacuum leaks can cause engine performance issues. When there is too much air and not enough fuel in the engine due to a vacuum leak, the engine may experience stalling, stuttering, or lag in acceleration. This fuel-starved condition hinders the engine's performance.
