Lexus cars are popular for their excellent performance and attractive design. However, your Lexus is almost useless without a cooling system to regulate the engine’s temperature. The coolant is a vital liquid in the cooling system that removes heat from the engine.

A coolant leak from any part of the cooling system is a sign of trouble. Once this fluid gets below a certain level, the engine could overheat and stop functioning. Hence, this guide will address the common causes of coolant leaks and what to look out for so you can fix any issue that arises with your car.

What are the Common Signs of Coolant Leakage in a Car?

Here are some common signs of coolant leakage in your car. Once you notice any of these signs, you should carefully inspect your car and get help from a professional mechanic.

1. Low Coolant Level

If your car’s coolant level is always low, no matter how recent your last refill was, it could be an indication of a leak from the cooling system. This is an obvious sign of leakage and you may need a mechanic’s help to identify the exact source of the leak.

2. Engine overheating

The main function of the coolant in the engine is to regulate its temperature by removing engine heat. Once the engine starts to overheat, it is a tell-sign that the coolant is not doing its job and one of the reasons why this could be so is that there isn’t enough coolant left due to leakage in the cooling system.

3. Strange smells from the engine

Another way you could tell that coolant is leaking from your car’s engine is based on the smell. It could be a sweet smell coming in through your car’s vents which is the smell of coolant. It could also be a burning odor which indicates that leaking coolant has been heated with the extreme heat produced in the engine, producing a smell similar to that of burning fuel.

4. Coolant pool beneath your car

If you notice that fluid pools under your car, especially close to the engine’s location, then it could be a coolant leak. You can differentiate a coolant leak from other oils based on the smell or color. If the fluid appears to be pink, yellow, or greenish, then your car is surely leaking coolant and you need to have it checked immediately.

Top 3 Causes of Coolant Leaks in a Car

There are several reasons why your car could be losing coolant; here., we have identified the top 3 reasons and what to do in such a situation.

Radiator Leaks

The radiator is a component of the cooling system and coolant passes through it during the process of cooling the engine. If the radiator gets damaged or broken, then any fluid that goes through it could leak out. This is why it is important to perform routine vehicle checks to identify the slightest sign of damage before it gets worse.

Broken Reservoir Cap

The coolant reservoir holds the coolant while the engine performs its function and it is sealed by a reservoir cap. However, if this cap gets broken or loose due to thermal stress or other factors, the coolant that it keeps could start to leak out.

Broken water Pump

The water pump does the act of moving coolant through the cooling system. If the water pump gets cracked or broken at any point, coolant could leak out from the damaged parts.
