Your car’s radiator is a critical component of the car's engine cooling system. Without a well-functioning radiator, the engine will not function properly and may overheat. Over time, contaminants like debris, dirt, and rust can accumulate inside the radiator, reducing its cooling efficiency. To prevent the engine from overheating and prolong the life of the cooling system, radiator flush and cleaning services must be performed at regular intervals.
Why Radiator Flush and Cleaning is Important for Your Car
The radiator flush and cleaning service removes old and contaminated coolant, debris, and rust deposits from the radiator. It is an essential service for the maintenance of your car’s cooling system to ensure optimal performance and efficiency.
Prevents Engine Overheating
With regular operation, the coolant degrades, leading to rust or sediments that clog the radiator. This reduces the radiator’s ability to regulate engine temperature and causes overheating. A radiator flush and cleaning service thoroughly cleans the whole cooling system. It also helps unclog blockages, and fresh coolant enhances cooling efficiency.
Improves Engine Efficiency
The radiator flush and cleaning service introduces fresh coolant into the cooling system. This enhances the system's heat-carrying capacity and ensures the engine runs at optimum temperature. This offers consistent engine performance even during long drives or heavy traffic.
Extends Radiator Lifespan
Regular radiator flush and cleaning removes rust and debris from the cooling system and prevents internal corrosion. It reduces the chances of expensive repairs in the future by extending the radiator’s life.
Protects Engine Components
A well-functioning radiator keeps the engine at optimum running temperature. Thus protecting critical engine components such as gaskets, hoses, and seals from overheating-related damages.
How to Flush Your Car Radiator
A radiator flushing service involves draining the old coolant, cleaning the cooling system and then refilling it with fresh coolant. Below is the detailed step-by-step process.
- Draining Old Coolant—The old coolant is drained through the radiator drain plug.
- Cooling System Flush—Close the drain plug and fill the radiator with the flushing solution to clean the cooling system. Run the engine for about 10 minutes to ensure the circulation of the cleaning solution throughout the cooling system, including the cooling jacket, the hoses, and the radiator.
- Draining the Flush—After shutting off the engine, the radiator drain plug is opened to drain the flushing solution.
- Filling Fresh Coolant—Once the flushing solution has been drained, the drain plug is closed, and fresh coolant is filled. It is recommended to use the coolant and anti-freeze mixture as per your manufacturer’s specifications.
When to Perform a Radiator Flush
Radiator flush and cleaning service is required every 50,000 km or 5 years, whichever is earlier (check your car’s owner’s manual). Other signs of flushing the radiator are—Frequent engine overheating, discoloured or dirty coolant, and coolant puddles under the car. In the case of coolant puddles, additional inspection of the cooling system is required to find potential leaks.
Tips for Radiator Maintenance
It is crucial to maintain your car’s radiator in top condition. Below are simple tips to follow.
- Always use the right type of coolant for your vehicle, which is recommended by the manufacturer. Filling with incompatible coolant can reduce cooling efficiency or cause internal damage.
- Ensure timely inspection of the cooling system for visible signs of rust, leaks, or damage to hoses.
- During every inspection, always check the level of coolant in the reservoir. Low levels of coolant can lead to engine overheating. Inspect and top up coolant regularly, especially before long journeys.
- Ensure the cap is tightly sealed and in good condition to maintain the correct pressure within the system.
- Regular radiator flush and cleaning must be performed at right intervals to maintain your car’s radiator
Self vs Professional Radiator Flush and Cleaning Service
While the radiator flush and cleaning can be performed at home, it is recommended to get it done at fully-equipped garages. A car workshop like FourDoor has all the specialised tools, flushing machines, and skilled mechanics who perform the service quickly and efficiently. Below are the differences between professional service and DIY.
| Service Aspect | Professional | DIY |
| Cleaning Process | Expert radiator flushing and cleaning process | Car owners do not always have experience in radiator flushing and cleaning |
| Time Required | Professional radiator flush and cleaning is completed within two hours at FourDoor | Due to a lack of experience, the radiator cleaning process could be time-consuming |
| Equipment Needed | Fully equipped garages have all the required equipment to perform the service | DIY service requires the purchase of equipment, which could be expensive |
| Risks of Mistakes | There are minimal chances of mistakes by experienced mechanics | There are higher chances of mistakes that can lead to expensive repairs |
Conclusion
Efficient engine cooling is only possible if the radiator is functioning at its best performance. A timely radiator flush and cleaning service protects it from internal corrosion and damage. It is wise to perform radiator maintenance at regular intervals to avoid unexpected breakdowns and drive worry-free.
FAQs
Q. Is a radiator flush necessary for my car?
Yes, a radiator flush is essential for maintaining your car’s cooling system. Radiator is required in about 5 years or 50,000 km, whichever comes first. Over time, debris, rust, and old coolant can clog the radiator, reducing its efficiency and risking engine overheating. Regular flushing ensures proper heat dissipation, prolongs the radiator’s lifespan, and protects the engine.
Q. How to clean and flush a radiator?
Cleaning and flushing a radiator involves these steps:
- Drain the old coolant from the radiator.
- Fill the radiator with a flushing solution.
- Run the engine for a few minutes to circulate the solution and loosen debris.
- Drain the solution and rinse the system.
- Refill with fresh coolant and antifreeze mixture as per your vehicle’s specifications.
Q. How much does a radiator flush cost?
At FourDoor, the cost of radiator flush and cleaning service for compact hatchbacks starts from ₹2,299. The price will vary depending on the vehicle and engine size.
Q. What will happen if I skip the radiator flushing for my car?
Skipping a radiator flush can lead to several problems:
- Engine Overheating: Old, contaminated coolant loses its effectiveness, causing the engine to overheat.
- Clogging of Cooling System: Rust and debris can clog the radiator and cooling system, reducing efficiency.
- Internal Corrosion: Without fresh coolant, internal components may corrode, leading to leaks and damage.
- Costly Repairs: Neglecting flushing can result in expensive repairs or even radiator replacement.
