6 Reasons For Foul Smell And Brown Car Cooling System
The sources for this issue are diverse, from radiator leakage to clogged engine coolant. This is predominantly because all the elements in a vehicle are interconnected. Hence, dysfunction of one unit can bring about troubles like smelly car cooling with brown discharges. Check out the six conditions that can lead to such issues.
1. Leaking Radiator
Radiators are the chief constituents of cooling systems. Hence, radiator leakage is one of the major reasons. In fact, it indicates that it has been leaking for quite some time now. Brown discharge and smelly cooling system signify that the leakage has escalated and is also affecting other systems.
2. Corrosion and Contamination
The primary reasons that can be considered are rusting in the radiator or contamination of the reservoir liquid. The antifreeze for cars constitutes 50% of the liquid, and the rest is water. If this antifreeze turns brown, some parts of the reservoir will suffer from corrosion or succumb to contamination. Hence, you must immediately seek professional assistance to avoid further deterioration. This also leads to a rusty smell in the car.
3. Clogged Cooling System
Sometimes, the accumulation of debris in the radiator might lead to this issue. The debris accumulates barriers to the cooling system’s function of removing heat from the engine. Other causes include low water levels in the coolant tank due to blockage from dirty hoses and filters. Hence, we suggest periodic cleaning of these components to identify and initially resolve these issues. However, make sure you choose good quality radiator cleaners for desirable results.
4. Overheating
Another major factor is when the car cooling system cannot function efficiently, leading to engine overheating. Some major things that can culminate in overheating are corrosion, debris accumulation, oil contamination, failing heater core, and formation of air bubbles. When the engine rises above the optimum temperature, you notice a brownish coolant and a foul smell.
5. Misfitting Radiator Cap
Ever heard of the phenomenon of ‘boiling over’? It is referred to when your coolant starts boiling due to increased air pressure and becomes brown. Well, the next question arises: why would my car coolant boil? Engines are provided with a radiator cap that prevents the coolant from escaping. However, they are usually ensured to be tight-fitting. An ill-fitted radiator cap will let air particles into the radiator, turning it brown.
6. Pitting And Air Bubble
When the metal reacts with the acid in the coolant, it causes rust and corrosion, leading to brown coolant and foul odour. This is known as pitting. It can also lead to the formation of air bubbles, which comprise the liquid’s ability of the coolant reservoir tank to transfer heat. This overheating can lead to these troubles in your car.
What Is The Solution for Malfunctioning Car Cooling Systems?
The immediate and principal way out is instant radiator flush. Here, technicians will flush out the contaminated antifreeze and water mixture by pouring fresh and clean liquid. This will enable the car cooling to function properly and prevent overheating. Hence, make sure you frequently check the condition of the reservoir liquid.
Another fundamental solution is radiator leak repair. If you have recently become the proud owner of a car and hence are naive to these technicalities, never DIY such things. You are always advised to seek professional help for the best outcomes.
‘Prevention is better than cure’ – we have all heard this proverb since childhood. Remember to opt for professional car repair Perth services for a thorough checkup of your car.
