Diagnosing Car Problems: Step‑by‑Step
Accurately diagnosing a car problem is the first step in ensuring it’s fixed correctly. Here’s a general process to help you understand what might be wrong:
Step 1: Listen and Observe
Auditory Cues:
Pay close attention to any unusual sounds—such as grinding, knocking, or squeaking—especially when starting the car, accelerating, or braking.Visual Inspection:
Check under the hood for any obvious signs of leaks, damaged components, or corroded battery terminals. Look at the tires for signs of uneven wear or low pressure.Dashboard Warnings:
Modern vehicles are equipped with sensors that alert you to problems. Take note of any warning lights, such as the check engine light, battery warning, or ABS indicator.

Step 2: Check Fluid Levels and Conditions
Engine Oil:
Use the dipstick to check oil levels and look for signs of contamination (such as a milky appearance, which could indicate coolant mixing with oil).Coolant:
Ensure that the coolant reservoir is filled to the proper level and that the coolant appears clean.Brake Fluid:
Inspect the brake fluid in the reservoir for proper levels and clarity.Transmission and Power Steering Fluids:
These should be checked periodically to ensure they are at the correct levels and in good condition.

Step 3: Perform Basic Diagnostic Tests
While a professional mobile mechanic has advanced tools, there are some simple tests you can perform at home:
Battery Voltage Test:
Use a multimeter to check the battery voltage. A fully charged battery typically shows around 12.6 volts when the car is off.Brake Pedal Test:
Press the brake pedal and note if it feels firm or soft. A spongy pedal might indicate air in the brake lines or low brake fluid.Tire Pressure Check:
Use a tire pressure gauge to ensure all tires are inflated to the manufacturer’s recommended levels.
