Prestone Radiator Flush Review

Radiator flush is a cleaner that you use to clean your engine cooling system. Radiator flush is especially important for used cars that have been sitting idle, or cars driven in cold climates.

In order to improve radiator performance, engine heat should be removed from the water being pumped around a vehicle’s cooling system. Not only does this help keep a car cool, but it also helps prevent the engine from overheating and helps increase fuel economy. For these reasons, many people choose to flushing their vehicle’s radiator at the beginning of each new heating cycle. In order to use a Prestone Radiator Flush, simply check off the “cold” box when entering your vehicle information on the product page so that you get a mix of coolant and water. When ready to begin flushing your vehicle’s cooling system, drain it as usual by loosening a hose clamp with a wrench, then remove the radiator cap and pour the fluid into the radiator until only about three inches of fluid remain in both sides. Use a funnel or other device to help add more fluid if needed. Some people choose to add up to half a gallon of Prestone Radiator Flush for larger vehicles such as RVs or trucks before adding fresh coolant from antifreeze containers.

After this, simply drive your vehicle for about fifteen minutes before re-checking the coolant levels to determine if more fluid is needed or whether you should refill with just plain water to dilute the amount of Prestone Radiator Flush used. To keep flushing your radiator at regular intervals, consider buying a two pack of Prestone Radiator Flush to keep your engine healthy and operating efficiently.

Deposits can dramatically restrict coolant flow and reduce heat transfer, which may lead to possible overheating, breakdown, or costly repair. A super-chelating additive effectively removes heavy deposits by drawing metal oxides into the solution. Though strong enough to help restore maximum cooling system efficiency, this non-toxic, non-acidic product is easy-to-use and safe for all cooling system metals.

Prestone Radiator Flush Review

Prestone radiator flush is a radiator additive that is designed to keep your cooling system clean. The car’s coolant circulates through the engine and carries away its heat, allowing the engine to function properly. This fluid flows through many different metal parts before being cooled by air flowing over the radiator. Over time, sludge and rust build up inside the cooling system, resulting in reduced ability of the coolant to transfer heat.

Radiator flush can also clean other components including heater core and water pump. Some radiator flushes contain additional detergents that may help remove deposits from engine oil or transmission fluid. They should not be used for this purpose, however, as they are not designed for these fluids and can damage engine components.

How to Use Prestone Radiator Flush

Prestone Radiator Flush Review

The Prestone Radiator Flush is one of the most popular products to clear a car’s radiator. The product claims to “clean” a car’s cooling system and leave it running more efficiently by removing rust, sediment, and scale from the engine block that could block water flow or have mixed in with old coolant.

In order for this product to work properly, you must first change your car’s antifreeze with a 50/50 mix of new antifreeze and distilled water. If you do not make this change before using this product, then you will need to change your coolant again immediately after finishing the procedure, as the product will flush out all of your current coolant. This means you can not use this product in a garage or driveway, but instead must take your car to a professional station that offers free-flushing.

Once you have changed your coolant and mixed Prestone with water in the new reservoir, drive your car for 15 minutes to circulate the solution through the engine block. In order to get it into all of the engine block’s small crevices, it may be helpful to go through a drive-thru or attend to some shopping errands.

After the 15 minutes are up, turn your car off and allow it to idle for 10 minutes. This will give time for the solution in your radiator system to cool down so you can safely open the radiator cap. When the 10 minutes are up, open your radiator cap and drain all of the solution from your cooling system via the catch-container. Finally, pour in distilled water only to the cold radiator reservoir until it is full.

The Prestone Radiator Flush can remove rust scale buildup that coats an engine block’s metal surfaces. This buildup occurs over a long time and is a common cause of corrosion. The solution can help remove sediment from the radiator as well, but typically you should replace your radiator every 5 years regardless to prevent corrosion damage, which could lead to more costly repairs or even engine failure.


·        Do not open your radiator cap while the engine is hot.

·        Make sure to use a designated catch container for draining the radiator fluid.

·        Do not pour the Prestone mixture into your car’s oil pan. Doing so can cause permanent damage to your engine and cooling system.

·        You should always consult with a professional mechanic before attempting any maintenance on you car’s cooling system or engine block.
