The radiator is an essential part of a car’s cooling system. It uses water or coolants to prevent overheating of an engine. This water can leak from the radiator, a problem commonly identified by fluid drips under the car and excessive overheating of the engine. There are many causes of water leaking from the radiator, and no matter how minor the reason is, it is important to fix the issue before it leads to bigger problems.<\/p>\n\n\n\n

This guide lists down the seven most common reasons behind radiator water leaks, along with some basic tips to prevent them.<\/p>\n\n\n\n

7 Reasons of Water Leaking from the Radiator<\/h2>\n\n\n\n

Radiator water leak from the vehicle is a serious concern for drivers in the UAE. Excessive heat increases the need to keep your radiator cool<\/a>. In this situation, a leaking radiator can cause significant damage to the car engine and other parts. Therefore, it is essential to identify the potential cause of the water leak in the radiator and fix it. We have listed some major causes of radiator water leakage below.<\/p>\n\n\n\n

Corrosion<\/h3>\n\n\n\n

Radiators age under the constant pressure and heat generated by an engine. Due to heat and pressure, the radiator starts to corrode and wear out after a certain time period. Rust and corrosion create minute cracks in the radiator that allow water to seep. Other radiator parts such as the radiator fan can also get damaged due to corrosion. You must check the symptoms of a bad radiator fan<\/a> to avoid car overheating.<\/p>\n\n\n\n

If you leave them untreated, these cracks turn into holes, causing excessive water leakage.\u00a0<\/p>\n\n\n\n

Leaked Radiator Gasket<\/h3>\n\n\n\n

A radiator gasket is a sealant between radiator and cooling system. It is made out of plastic and can get melted by heat and pressure. Any potential leak in the sealant will cause water leaking from the radiator.<\/p>\n\n\n\n

Punctured Radiator Hoses<\/h3>\n\n\n\n

The radiator hose carries water in the cooling system. These hoses are made from reinforced synthetic rubber and can bear temperatures up to 148\u00b0C. However, the temperature of an engine in the UAE often gets beyond this limit and punctures these hoses. Inspection of hoses is also considered an essential step to find leaks in your car\u2019s cooling system<\/a>.<\/p>\n\n\n\n

Failed Water Pump<\/h3>\n\n\n\n

Water leaking from the car radiator can also be due to the failed water pump. This pump is responsible for circulating water in the hoses and radiator. The main reason for the water pump malfunctioning can be external damage, as It is located in the lower part of the engine. Other than that, loosen radiator hose connections can also cause leakage.<\/p>\n\n\n\n

Blown Head Gasket<\/h3>\n\n\n\n

The blown head gasket is often characterized by cracks that allow oil, fuel and radiator water to mix. This can result in overheating or short circuits in fuses. In worst scenarios, these cracks can leak radiator water and other fluids that are essential for your car<\/a> causing a complete engine failure.<\/p>\n\n\n\n

Faulty Expansion Tank<\/h3>\n\n\n\n

The expansion tank supplies coolant or water to the radiator. It is a plastic container connected with a radiator through a hose. High temperature or external hits can leak this plastic tank results in water leaking from the radiator.<\/p>\n\n\n\n

Compromised Radiator Cap<\/h3>\n\n\n\n

Cap creates a tight seal to withhold steam generated inside the radiator. If the cap does not fit properly or the spring is worn-out, it will allow the steam to escape. This escape will result in a lower water level inside the radiator which is an indication of water leakage. It is the least effective issue and the most convenient one to fix. You can buy auto accessories for sale in the UAE<\/a> and simply replace your old cap. <\/p>\n\n\n\n

Preventive Measures to Avoid Radiator Water Leak<\/h2>\n\n\n\n

Water leaking from the car radiator does not trouble driving, but it is a serious issue. Often, it requires professional assistance to fix leaking issues. You can prevent it by taking the following preventive measures. <\/p>\n\n\n\n
