One of auto problems is tire sidewall cut that appear in the consequence of strong blow. It can be entry into a deep pothole, a boosting of a railroad passage at the high speed and other extreme actions on tires. The sidewall cut is a total rupture over sidewall cord threads and a dissection of visible tire facing. Sidewall cuts up to 120 mm are considered repairable. To check the repair result a tire should be filled with air over the maximum value. Auto problems troubleshooting is very popular question indeed.
Engine auto problems are the most common among auto problems. Let’s check some of the rifest troubles.
Ignition system is on, a starter revolves crankshaft but engine is not started. The possible reasons:
Ignition system problem, in layman’s terms called “no spark” that means the combustible mixture goes into cylinders, but there is no sparking necessary for ignition occurs in the compression chamber.
Spark plugs problems. Exceeding of the service period, electrodes burnout, carbon fouling on electrodes, fouling by fuel combustion products, as well as a puncture of ceramic insulator can complicate engine start or make it impossible. The fewer cylinders you have, the more difficult it is to make the engine work.
High-voltage part of the ignition systems failure. These auto problems can be caused by increased humidity after heavy showers, fogs, wet snow, as well as after bad motor section washing, in rare cases by very low temperature. You can hear pops in the muffler, but it is very hard or even impossible to start the engine.
Electronic part of the ignition system failure. These auto problems are quite serious and can be caused by ignition module breakdowns, park spacer breakdowns, sensors malfunction of crankshaft and camshaft position.
Fuel injection troubles.
Sometimes one can encounter with serious auto problems like engine overheating that can be caused by stuck closed thermostat, external coolant or anti freeze leak, engine water pump failure and electric fan or fan hub breakdown.
Auto ploblems troubleshooting is simple!
Almost all modern cars have Check Engine light indicator on a dashboard. When it’s turns on it reports that electronic control systems sees some troubles. There are different auto problems that can turn the indicator on, from carburetor snag to engine rpm speed, gearshifts in the automatic transmission, combustible mixture composition, ignition point etc. But the most common reason is combustion miss of one of the sparks. If the indicator turns on the move, there is no reason to panic. Stop the car, check oil level, visual damages and other visual auto problems, and follow to the nearest garage for vehicle health check.
One of the most annoying auto problems are car noises. Some of them like bad wheel housing sound insulation or squealing driver’s seat can just set the teeth on edge, but others are due to serious technical auto problems.
Zizzing sound then turning a steering wheel most likely related to power steering fluid leakage or the steering linkage. Flapping sound testifies of belt disintegration or that something is interfering with the fan.
Raspy manual transmission when shifting can be due to a clutch issue or deeper problem of the transmission itself.
Hissing sound under the hood can be due to coolant or oil leakage onto a heated engine.
