At the heart of your car's cooling system is your BMW 740i radiator. Technically speaking, your 740i radiator is not in the center of your engine. Rather, you will find your BMW 740i radiator near the front of your engine bay.

You may be aware that your engine relies on a mixture of coolant and water to keep the operating temperature as low as possible (without freezing in the winter). The function of the 740i radiator is to enable your coolant to release the heat it absorbs from your engine.

Your BMW 740i radiator is a series of tubes and chambers designed to hold a vast amount of fluid. The tubes of your 740i radiator are flanked by vertical or horizontal fins, which serve as barriers for the inside of the radiator. When heated coolant enters your BMW 740i radiator, it is spread out through the tubes to achieve more surface area. Air entering your engine through the grille serves to lower the temperature of the coolant in the 740i radiator. The coolant continues out of the BMW 740i radiator through a radiator hose, and then back through the engine to absorb more heat. Your 740i radiator features an upper and lower radiator hose for coolant intake and output. If your BMW 740i radiator springs a leak, you should first check the clamps and the area around the radiator hose. Otherwise, a leaking 740i radiator may be due to rust or corrosion resulting from normal wear. Your BMW 740i radiator may also stop working due to internal blockage, which can result from failure to regularly flush and clean your 740i radiator.Browse our online catalogue for a high quality replacement BMW 740i radiator, in stock and ready to ship to your door.
