To diagnose car problems, identify the specific problem and the symptoms associated with it. Common problems with cars include failure to start, uneven tire wear and noisy brakes. Other common problems include high engine temperature, poor gas mileage, oil leakage, faulty air conditioner and awkward shifting.
A worn out battery or misfiring sparks plug may prevent the engine from starting. To rectify this, replace the battery, adjust the battery terminal connections and replace the spark plugs with new and clean ones. Lack of routine tire rotation causes uneven tyre wear, and to resolve this problem, rotate the car tires each time you change the oil.
A defective brake pad or a faulty rotor may cause a grinding noise in the brakes. To resolve this, replace the brake pad, and resurface the car rotors. The engine may overheat when the radiator or the hose is faulty or coolants are depleted. To resolve this, repair fan motor connections and fan thermostat. A faulty oxygen sensor or loose and missing gas cap may cause poor gas mileage. Replacing the oxygen sensor and tightening the gas cap may help to solve this problem.
A damaged exhaust system may cause oil and fuel leakage, and to resolve this, consult the manufacturer for a detailed description on what parts need to be replaced. A faulty A/C compressor may cause lack of air circulation in the car. To diagnose this, consult a mechanic for a thorough repair. A low level of transmission fluid causes the transmission system to hold the gears longer, resulting in awkward shifting . Refilling the transmission fluid to the recommended level can resolve this.
