Cooling system cleaner for maximum cooling performance – removes limescale, rust and deposits and protects against overheating.
Concentrated Radiator Flush Cleaner – Deep Cleaning for Maximum Cooling Performance
The Concentrated Radiator Flush Cleaner from AUTOGAR® is a powerful cooling system cleaner designed to restore
maximum cooling efficiency and protect the engine from dangerous overheating. Over time, limescale, rust, sludge, and oil residues
build up inside the radiator, water channels, and heat exchangers, restricting coolant flow and reducing the system’s ability to
dissipate heat. This Concentrated Radiator Flush Cleaner quickly and effectively dissolves these deposits, helping the coolant to
circulate freely again and ensuring stable engine temperatures under all operating conditions.
A dirty cooling system is one of the most common causes of overheating, loss of performance, and expensive engine repairs. Even a
partially blocked radiator can significantly increase engine temperature, especially in traffic jams, hot weather, or under load when
towing or driving uphill. By using Concentrated Radiator Flush Cleaner as part of your maintenance routine, you can
restore the original heat transfer efficiency of the system and ensure that the coolant can do its job properly – absorbing and
releasing heat with maximum effectiveness.
How Concentrated Radiator Flush Cleaner Works
The cleaner uses a highly active yet gentle formula that circulates through the entire cooling system and targets stubborn deposits.
It loosens limescale from heat-exchange surfaces, dissolves rust from metal components, and breaks up sludge and oily residues that
form when coolant ages or mixes with engine oil. As the Radiator Flush Cleaner works, contaminants are
suspended in the flushing liquid so they can be drained out completely when the system is emptied.
Despite its strong cleaning performance, the formula is designed to be kind to metals, seals, gaskets, and hoses. It does not attack
aluminum radiators, rubber seals, or plastic components, which makes it ideal for regular use during coolant changes or repairs. This
gentle but effective balance allows you to maintain a clean cooling circuit without compromising the integrity of the system.
Optimized Cooling Performance & Long-Term Protection
Once the deposits are removed and coolant can flow freely again, the radiator and heat exchanger are able to dissipate heat much more
efficiently. This results in more stable operating temperatures, improved reliability in demanding conditions, and reduced risk of
overheating-related damage such as warped cylinder heads or blown gaskets. A clean cooling system also supports more consistent
performance from the thermostat, water pump, and fan control.
Regular use of Concentrated Radiator Flush Cleaner can extend the service life of the entire cooling system. By
eliminating corrosion-causing residues and improving the effectiveness of fresh coolant, it helps to prevent future rust formation
and internal blockages. This proactive maintenance not only protects against breakdowns but also reduces long-term repair costs.
Easy Application for Professional Results
The product is easy to use and does not require disassembly of the system. Simply add the Concentrated Radiator Flush Cleaner to the
cooling system according to the instructions, run the engine to allow it to circulate and act, and then drain and flush the system
before refilling with fresh coolant. This makes it suitable for both DIY users and professional workshops looking for a reliable,
high-performance radiator flush.
