Keep the rust away this winter. Wash your car as often as possible. It makes a difference and helps your car last through the winter, sand & salt are a cars worst enemy.

How Radiator Works in Automobile? Easiest Explanation How does a Radiator Works? Radiator has a number of flat and thin pipes arranged horizontally one below ...the other. Water flows through these pipes along their length. But how does the water flowing through these pipes gets cold so fast. So to increase the heat exchange from water to air, we have fins brazed between the flat surfaces of these pipes. These fins between the pipes looks like a dense sine wave (trigonometric function).Thus increasing the surface area that comes in contact with air and increasing the heat exchange. Is it all we have in a radiator to exchange heat? Then no, we are not done yet. High end car radiators are bit more sophisticated, we have fins like structures inside the radiator pipes. These are added to create turbulence in the water flowing through them. The water flowing through pipes without internal fins is streamline. Thus the heat exchange will be between outer layer of water and the air. As the outer layer of water gets cooler, It reducing the temperature difference between air and water as a result, rate of heat exchange will decrease. Whereas in the radiator pipes with internal fins, water molecules that exchanges heat with air gets mixed up with hot water, due to turbulence created by these fins. Thus keeping the temperature of whole water uniform and high. In this way a greater amount of heat could be exchanged and coolant gets cooler at a really very fast pace. What is the function of pressure cap in a radiator? Temperature of engine goes way much higher than 100 degree centigrade, and water is used as a coolant in cars. But water starts boiling at 100 degrees and get converted into steam. And steam does not exchange heat at a good pace. So how water can be used as a coolant. To solve this problem pressure caps are introduced in a radiators. Pressure cap does not allow the pressure formed in the radiator to escape created by hot water coming from engine .
