A royal guide to keeping your cool: What to do when your car overheats

So, there you are… Cruising down the N1, the wind in your hair, your playlist pumping… And suddenly, your car throws a tantrum and the temperature needle shoots up faster than your blood pressure. Yep, your car’s overheating. Don’t sweat it (literally), because the king’s got a cool guide to help you handle this hot mess.

First things first: What does ‘overheating’ actually mean?

In royal terms, your car is experiencing a royal meltdown. Literally. The engine’s cooling system can’t keep up with the heat being generated, and things start to sizzle. This can be caused by a number of pesky culprits, including:

  • Low coolant levels.
  • A leaking radiator.
  • A broken thermostat.
  • A faulty fan.
  • A busted water pump.
  • Driving in scorching heat or heavy traffic for too long

Whatever the cause, an overheating engine is a big red flag (and not the kind of flag you wave at rugby).

How to stay cool when your car overheats

Pulling over and panicking isn’t a plan, but pulling over safely is. Here’s what you need to do:

  1. Turn off the aircon and turn on the heater

Yep, it sounds mad, but turning on the heater helps transfer some of the engine’s heat into the cabin (hot car, cooler engine).

  • Find a safe spot to pull over immediately

Don’t risk permanent damage. As soon as it’s safe, pull off the road and switch off the engine.

  • Wait for the engine to cool down

Don’t pop the bonnet right away unless you fancy an impromptu facial steam blast. Give it at least 15-30 minutes.

  • Check the coolant level

Only do this once the engine is cool. If it’s low, top it up with coolant (or water if you’re desperate). But this is a temporary fix. You still need to find the source of the problem.

  • Call for backup

Don’t try driving again if you’re unsure. Rather call in the cavalry. With King Price’s emergency assist, we’ll arrange a tow and help get you back on the road without breaking a royal sweat.

What NOT to do when your car overheats

  • Don’t keep driving. You’ll risk serious engine damage that could leave your wallet crying.
  • Don’t pour cold water on the engine. It might crack from the sudden temperature change. (Engines aren’t into ice-bucket challenges.)
  • Don’t open the radiator cap while it’s hot. That thing is under pressure and could spray boiling liquid at you. Not lekker.

How to prevent overheating in the first place

A wise policyholder once said, ‘Prevention is cheaper than a new engine’. Here’s how to keep things running smoother than a Springbok victory parade:

  • Check coolant levels regularly (and top up with the right mix).
  • Keep an eye on your temperature gauge.
  • Check your radiator, thermostat, water pump, and fan during services.
  • Watch for leaks (puddles under the car = not a good sign).
  • Don’t ignore strange smells, steam, or warning lights.

The king’s got your back when the heat is on

FAQs

What causes a car to overheat?

Overheating can be caused by low coolant, leaks, a broken thermostat, faulty fans, or excessive heat and traffic.

Can I still drive my car if it’s overheating?

Nope. You risk serious and costly engine damage. Rather pull over safely and call for help.

How long should I wait before opening the bonnet?

Wait at least 15–30 minutes. Opening it too soon can be dangerous.

Will King Price cover the damage from an overheating engine?

If the overheating is caused by a covered event (like accident damage), we’ll help you out. But if it’s from wear and tear or lack of maintenance, it’s probably not covered.
