Automotive radiators can get fouled with calcium and rust residue after only a couple of years of operation.
Left unchecked, this may result in decreased heating performance, engine overheating and damage to the radiator and other cooling system parts.
Periodic flushing will continue to keep your cooling system in prime condition and your engine operating in the correct operating temperature.
Step 1: Make sure the engine is cool
Drain the radiator by eliminating the cap and opening the drain plug at the bottom of the radiator.
Close the drain and fill radiator with water and then operate the motor before the thermostat opens and water circulates through the engine block.
Step 2: Let engine cool and repeat the procedure
Simply Repeat ”Step 1” several times.
Step 3: Choose a cooling system cleaner that's safe for your engine model and radiator
Newer systems comprise aluminium components which might be damaged by a few cleansers. If you are not certain, ask your manufacturer.
Step 4: Tip the cleaner into the radiator and run the engine with the heaters turned on
Keep the engine running for as long as the manufacturer recommends.
Step 5: Drain and refill the cooling system with distilled water
Run the motor, allow it to cool and replicate the procedure at least one time to make sure that the entire clean-up solution has drained out of the motor.
Step 6: Choose antifreeze that is recommended by your Car Manufacturer
Add enough antifreeze into the radiator to reach a 50 to 70% concentration. If your heating system holds 10 litres of liquid, then add 5 to 7 litres of antifreeze.
Step 7: Finish by filling the radiator with distilled water
Run the motor, allow it to cool and top off the radiator and toaster with antifreeze.
