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.
This guide lists down the seven most common reasons behind radiator water leaks, along with some basic tips to prevent them.
7 Reasons of Water Leaking from the Radiator
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. 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.
Corrosion
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 to avoid car overheating.
If you leave them untreated, these cracks turn into holes, causing excessive water leakage.
Leaked Radiator Gasket
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.
Punctured Radiator Hoses
The radiator hose carries water in the cooling system. These hoses are made from reinforced synthetic rubber and can bear temperatures up to 148°C. 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’s cooling system.
Failed Water Pump
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.
Blown Head Gasket
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 causing a complete engine failure.
Faulty Expansion Tank
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.
Compromised Radiator Cap
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 and simply replace your old cap.
Preventive Measures to Avoid Radiator Water Leak
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.
- Check your radiator water at a regular interval of time.
- Immediately replace worn-out caps.
- Get your clogged radiator cleaned by a professional.
- Keep your coolant temperature sensor in working conditions.
- Fill the expansion tank at least once a week.
Radiator leaking water seems to be a minor fault, but it can create a life-threatening situation. Generally, it gets corroded due to temperature and pressure created by the engine. Therefore, corroded and rusted radiators are common in older cars. If you are looking for an old car with perfectly working radiator browse through these used cars for sale in the UAE.
FAQs
What to do if water is leaking from the radiator?
The radiator leaks can be stopped by identifying faulty parts and replacing them. However, for an immediate solution you can use radiator leak sealant which can stop leakage for some time.
What problems can a leaking radiator cause?
A leaking radiator can overheat the engine, blow head gasket, spark plugs or crack block. In extreme conditions leaking radiator can result in complete engine failure.
What is the most common cause of radiator leak?
The most common cause of water leaking from the radiator are corrosion and rust which develops in the radiator due to excessive temperature and pressure.
