You don’t need a scanner or a lift to see a breakdown coming—just a trained eye and a few seconds around your car. After 20+ years working dealership floors and now pulling people out of roadside nightmares, I’ve learned this: most breakdowns show signs before they happen.
You just need to know where to look.
Here’s a quick visual walkaround that could save you a callout, a tow bill, or worse.
1. Battery Terminals Crusted Over
What it means: Corrosion equals resistance. Resistance equals no start. What to look for: White, green, or furry buildup around the terminals. And if your battery is more than 5 years old, it’s time to change it.
Pro tip: If it looks bad, it is bad. Clean it or replace the terminals before winter hits.
Bonus Tip: A quick way to check your battery’s health at home? Use a simple digital battery tester (Amazon link). It’ll tell you in seconds if it’s weak or borderline—before it leaves you stranded.
2. Tyres with More Cracks Than Tread
What it means: Dry rot or sidewall failure waiting to happen. What to look for: Small cracks in the tread blocks or sidewalls—especially if the tyres are more than 5 years old.
Pro tip: Don’t just check tread depth. Look for cracking, bulges, or exposed cords.
3. Coolant Below the Line or Mysteriously Disappearing
What it means: A leak—or worse, an internal engine issue. What to look for: Low reservoir, dry-looking overflow tank, stains around the radiator or under the water pump.
Pro tip: Check your coolant level monthly. Coolant loss with no drips? Time to sniff the exhaust fumes for head gasket failure.
4. Oil on the Underside or Driveway
What it means: Seals or gaskets are going—slow leaks always turn into big ones. What to look for: Wet oil pan, damp diff, or spots on your driveway.
Pro tip: A little oil makes a lot of mess. If it’s oily underneath, track it down before the level drops and the engine pays the price.
5. Loose or Missing Undertray/Guarding
What it means: A welcome mat for water and debris. Plus, it can rip off on the road. What to look for: Hanging plastics, missing clips, flapping undertray on a windy day.
Pro tip: Secure it now or it’ll become your next roadside souvenir.
6. Cracks in the Serpentine Belt
What it means: That belt drives everything—if it snaps, you’re done. What to look for: Cracks, fraying edges, or glazing (a shiny surface).
Pro tip: Belts should flex, not crack. If it looks tired, replace it before it lets go.
7. Gunked-Up Windshield Nozzle
What it means: Poor visibility = big risk. What to look for: Weak spray or jets that miss the screen completely.
Pro tip: Clear blocked nozzles with a pin. Top up with proper washer fluid—water alone doesn’t cut it in winter.
You don’t need a toolbox to prevent a breakdown—just ten minutes, your eyes, and common sense. This isn’t about being paranoid. It’s about not being stranded in a car park when it’s lashing rain and your battery just gave up the ghost.
Take a look today. Your future self will thank you.
