The car radiator can do a good job of engine cooling, and the radiator acts as a large heat exchanger placed in the high volume airflow area. The pump is then connected to the pulley at the front of the crankshaft via a serpentine belt, increasing the coolant flow as the engine speed increases. In order to extend the life of the car radiator and the car engine, flush the radiator.
Wait until the engine cools from running, so the coolant is at a safe temperature, remove the car radiator cover to release any internal pressure in the cooling system, jack up the front of the car and find the radiator drain plug, place a lower one below it The tray is so as to receive the coolant after release, unscrew the drain plug at the bottom of the radiator, allow the coolant to completely drain from the system, screw the drain plug back into place, and fill the coolant reservoir with cooling water.
Turn on the engine, then pump the liquid around the engine and car radiator, fill the coolant reservoir with coolant and antifreeze mixture, or use the premixed liquid to start the engine and allow any residual air bubbles to be released. Antifreeze can also be added in the post-flush stage as this prevents the same degree of corrosion from occurring again and extends the life of the car radiator.
