Do These Things if Your Car Radiator Overheats

Cars often overheat during periods of very hot weather. Although rarer in modern cars, even the most well-tuned vehicles can overheat.

If you find your car stuck in stop-and-start traffic or climbing steep gradient hills on a very hot day, your car’s dashboard temperature gauge could start rising or malfunction indicator lights might switch on.

There are a whole host of issues that can plague our cars during the summer months, so it is vital to be prepared.

It is useful to carry silicone hoses in your car, such as those by, for adding water to the engine.

Do these things if your car radiator overheats and help it regain its cool.

1. Open your windows and switch off the air conditioning.

When your car starts showing signs of overheating, switch off your air conditioning and open the windows.

This helps cool the engine and reduce its load.

2. Turn on the heater and blower.

If your car continues to overheat, switch on the blower and heater.

This transfers the heat to the passenger area of your car and away from the engine. This may prove slightly uncomfortable for passengers in your car, but it does wonders for an overheated engine.

3. Put the car in neutral

If you are stopped in traffic with the temperature gauge rising, shift the car into park or neutral and rev the car’s engine slightly.

Doing so speeds up the fan and water pump, which draws more air and liquid through the radiator. The increase in liquid and air circulation will cool things off.

4. Do not ride the brakes

In stop-and-start traffic, try to crawl along at a slow speed at slightly more than idle, and avoid moving up and braking repeatedly. This brake drag heats the engine up as the load it bears is increased.

5. Wait and cool the car

If you think your car may be close to boiling over, drive to the left side of the road, prop the bonnet open, and sit and wait until the car cools off.

Do not open the radiator cap or add water until the engine is much cooler.

If your car suffers in normal weather, there could be a leak in the cooling system, or your coolant and water level in the radiator might be low.
