Cooling System Flush & Service in Ledgewood

Cooling System Flush

A cooling system flush, sometimes known as a radiator flush, forces 4 to 5 gallons of anti-freeze through your vehicle’s cooling system. This pushes or flushes out all of the old anti-freeze and any contaminants that can build up. A flush guarantees that all of the old anti-freeze is removed from the system. Draining the cooling system on the other hand only removes about 50% of the total anti-freeze and leaves the majority of contaminants still in the system. It also means that the new anti-freeze will be mixing with the old. This cooling system flush should be performed when recommended by your vehicle owner’s manual to prevent vehicle overheating or radiator damage.

Why Knight’s Automotive Repair Recommends a Cooling System Flush:

Removes Rust and Scale Deposit - Over time rust and scale deposits build up within the radiator and cooling system. A flush removes these deposits which get pushed out along with the old anti-freeze. These build ups can cause overheating and even damage your radiator and cooling system.

Water Pump Lubrication - The additives in the coolant lubricate your vehicle’s water pump. This will lengthen the life of the water pump.

Removes Contaminants - A flush completely drains the system of the old anti-freeze which means that any contaminants that have made their way into the system will be flushed out. The additives in the coolant can lose important anti-corrosive properties over time which leads to the build- up of particles. A cooling system flush will remove these particles from the system.

Protect Against Rust and Foam - The new anti-freeze will have additives that help prevent rust and build up. It will also prevent foaming in the system which helps it operate efficiently.
