What is Hazard Relay?
The hazard relay controls the flashing of the hazard warning lights.
What is Heater Valve?
The heater valve is controlled by the interior heating controls. When you turn on your vehicle’s heat, the valve opens and allows hot coolant to enter the heater core, which then warms the air entering your vehicle’s interior.
What is Ignition Condenser?
The condensor soaks up excess electrical energy in an ignition system that has points. This prevents that extra energy from jumping across the points when they first open and close.
What is Ignition Module?
Part of the ignition system which instructs the coil to send voltage to the distributor.
What is Ignition System?
The ignition system contains the components that supply spark to your vehicle’s spark plugs. These include the battery, the coil, the distributor (including the cap and rotor), the spark plug wires, the ignition module, and the spark plugs themselves. Older cars also have ignition points and an ignition condensor.
What is Instrument?
An instrument measures levels of a certain system and provides a visual key for those levels. For instance, the gas gauge in your car measures the fuel level, while the temperature gauge indicates the engine temperature.
What is Ignition Points?
Part of the ignition system which instructs the coil to send voltage to the distributor. They do this by opening and closing, which turns on and off a circuit.
What is Head Gasket?
The head gasket seals the cylinder head to the engine block. It is subject to tremendous pressures, and often fails if and when an engine overheats.
What is Misfire?
When incomplete or no combustion occurs in one or more cylinders due to improper fuel, ignition, cylinder compression, or air.
What is LSD?
Limited-Slip Differential (LSD). An LSD senses the slippage of each wheel it sends power to and redirects power to the wheel with the most grip. Many high-performance vehicles have LSDs.
What is Lug Nuts?
Lug nuts attach a car’s wheel to its hub.
What is Leakdown Test?
A leakdown test is used to find excessive wear in an engine. When a technician performs a leakdown test on your vehicle, each cylinder is tested to see how well it holds pressure. If a cylinder is unable to hold pressure, your technician can pinpoint what component of the cylinder (piston rings, valves, etc) has…
What is Liability Insurance?
Liability insurance is coverage only for damage that you inflict on other people or their possessions. It does not cover theft or damage to your vehicle.
What is Ignition Switch?
This is the switch where you insert the key that starts your vehicle.
What is Idle?
When your car is on but not moving, and you are not touching the gas pedal, it is idling. For instance, when you are waiting at a stop light, your car is idling.
What is Idle Circuit?
This is a special kind of circuit found in a carburetor that only operates when the engine is at an idle.
What is Intake Manifold?
The intake manifold goes between your vehicle’s fuel system and the cylinder head(s).
What is Ignition Timing?
Timing refers to when the spark ignites the air/fuel mixture. Timing needs to be set exactly right for an engine to run correctly.
What is Manual Choke?
Manual chokes have a cable that lets the driver control the carburetor’s choke operation. Most newer cars with carburetors have automatic chokes instead of manual chokes.
