Why is the radiator leaking on Smart EQ fortwo?

Below, we will highlight the most common reasons for the radiator leaking on a Smart EQ fortwo.

Wear and Tear

One main reason for a radiator leaking on a Smart EQ fortwo is wear and tear, which happens over time. The core and seals of the radiator can worsen, causing small leaks that worsen over time.

Corrosion

Using non-compatible coolants and lack of correct maintenance will produce corrosion, causing a radiator to leak in a Smart EQ fortwo. It is essential to regularly inspect the radiator for corrosion and to use the correct coolant for the make and model of your vehicle to prevent radiator leaking on a Smart EQ fortwo.

Physical Damage

Accidents/collisions whilst driving or debris on the road can damage the radiator, causing the radiator to leak in a Smart EQ fortwo.

It is essential to drive safely and cautiously to prevent radiator leaking on a Smart EQ fortwo.

Pressure Buildup

Too much pressure in the cooling system can exert too much stress on the radiator, causing it to leak. This type of pressure build up can be due to a faulty radiator cap or a blocked or faulty thermostat.

Coolant Contamination

A common reason for radiator leaking on a Smart EQ fortwo is because of using the incorrect coolant that is not recommended for your Smart EQ fortwo or because of mixing different coolants. This causes chemical reactions that will damage the vehicle’s radiator, causing it to leak.

It is essential to follow your vehicle’s owner’s manual for the correct coolant type to use to prevent radiator leaking on a Smart EQ fortwo.

Poor Maintenance

The risk of a radiator leaking on a Smart EQ fortwo is increased if there is no regular inspection or maintenance such as flushing and replacing the coolant. Doing this will prevent sludge or debris buildup in the radiator.

Excessive Vibrations and Stress

A vehicle’s radiator structure can weaken as time passes by, especially if the vehicle is involved in high-performance driving or if there is extreme stress or vibrations on the engine. This will cause the radiator to leak.

Faulty Welds or Seams

Very rarely, faulty welds or seams can cause a radiator to start leaking on a Smart EQ fortwo. These are manufacturing faults which are not common and may show up later in the radiator’s life.
