Here’s a practical guide to common car problems and how to fix them yourself to save money and avoid unnecessary garage visits:
1. Dead Battery
Symptoms:
Engine won’t start, clicking noise, dim lights.
DIY Fix:
✔ Jump-start the car with jumper cables:
Connect red (+) to dead battery, then to working battery.
Connect black (-) to working battery, then to unpainted metal on dead car.
Start the working car, wait 2 mins, then start the dead car.
✔ Clean corroded terminals with baking soda + water.
✔ Replace the battery if older than 3–5 years.
Prevention: Turn off lights/electronics when parked.
2. Flat Tire
Symptoms:
Car pulling to one side, thumping noise, visibly flat tire.
DIY Fix:
✔ Change the tire with a spare:
Loosen lug nuts (while car is on ground).
Jack up the car (use the frame, not plastic!).
Remove nuts, replace tire, tighten in a star pattern.
✔ Patch small punctures with a tire repair kit ($10).
Prevention: Check tire pressure monthly.
3. Overheating Engine
Symptoms:
Temperature gauge in red, steam from hood.
DIY Fix:
✔ Pull over immediately to avoid engine damage.
✔ Let the engine cool, then check coolant levels.
✔ Refill coolant (50/50 mix with water) if low.
✔ Inspect for leaks (hoses, radiator, water pump).
Prevention: Flush coolant every 30,000 miles.
