CarsDirect identifies three of the most common problems that cause a car to switch off while a person is driving: broken or worn vacuum hoses, faults in the fuel intake system or an electrical wiring problem. Any one of these issues may cause a car to shut off randomly, but by following some basic troubleshooting steps, drivers might be able to pinpoint the source of the problem.Continue Reading
Vacuum hoses maintain the temperature and pressure around an engine. Over time, they become cracked and worn, which can cause the engine to stall. A vehicle's fuel intake system pumps fuel into the engine. If it gets clogged or starts to leak, an insufficient amount of fuel can cause the engine to shut off without warning. Finally, the vehicle's electrical system provides the spark necessary to ignite the fuel and power the car's engine. Faulty wiring can also cause vehicles to turn themselves off.
Sometimes, drivers can determine the source of the problem without a mechanic. They can check all the wiring and rubber hoses attached to the engine for leaks, cracks or other signs of extreme wear. They can also perform this check with the engine switched on to listen for the sounds of escaping air.Learn more about Car Parts & Maintenance
There are multiple ways to make a car faster, such as the installation of a new exhaust system, according to CarsDirect. New exhaust systems also make cars louder, but such alterations are not always legal, explains the Criminal Justice Degrees Guide.Full Answer >
Cars backfire for several reasons, including air and fuel mixing due to leaking hoses or other mechanical problems. Faulty spark plugs or wires can cause a car to backfire. It can also occur when shifting to a lower gear in a car with high horsepower.Full Answer >
Some of the most common causes for a car's stalling whilst driving include: a poor idle speed control, or ISC, system, low fuel pressure, loss of ignition and vacuum or EGR leaks. Diagnosing the specific problem should be a priority in order to get it fixed.Full Answer >
The purpose of a car water pump is to push coolant through the car's engine block, radiator and hoses to get the engine heat away from the system. Most frequently, the water pump drives off the crankshaft pulley or the crankshaft itself. The coolant that gathers between the impeller blades travels outward using centrifugal force, and suction draws the coolant into the water pump from the radiator.Full Answer >
