Always use a radiator anti-rust along with a radiator coolant. In Pakistan what one does is, switch off the engine, drain all the water from the radiator by unplugging the thermostat switch, re-plug the thermostat switch, top up the radiator with a radiator cleaner and wait for the period written in the instructions. After that drain the radiator again and put ample water into the radiator so that the chemical drains from the bottom of the radiator. Re-plug the radiator with the thermostat valve and fill it up with radiator coolant. Basically the radiator cleaner is sulphuric acid. You don’t run the engine when the radiator cleaning fluid is sitting in the radiator because if you do, it will damage the rubber seals of the water body (water pump) of the engine as running the engine will now give it access to the rubber seals of the water body.
