Specifications:Ĭomes in 3 foot section so you can cut to desired length. The hose is extra long so that it can be routed and cut for a perfect fit. This is an often overlooked hose which is notorious for deterioration. It is produced with correct 3/8" ID OEM style thin walled hose as original. This is a "3-rib" correct replacement hose for the radiator overflow. Radiator Overflow Hose 3/8" ID 3-Rib Design 3 Foot Length Functional Fluid, Lubricant, Grease (including Additives).So installing an overflow tank in your car is a good way to not only maintain the cooling system of your car but to save repairs and replacement expenses in the long run as well. In older vehicles with no coolant overflow bottle, the air is sucked into the radiator instead of coolant which results in the formation of rust. An expansion tank can easily be recognized by the neck and cap used. Expansion Tank Set Up: An expansion tank is part of the pressurized section of the coolant system. This decrease in volume will result in a vacuum because of a drop in pressure.ĭue to this vacuum, a vacuum valve in the radiator cap opens allowing the coolant which was flown into the radiator coolant overflow tank back into the radiator. One of the easiest ways to differentiate between an expansion tank and a recovery tank is whether the tank is part of the pressurized part of the coolant system or not. As it cools down, it will contract in volume as well. When the engine has been turned off, the coolant will start to cool down as well. See Also: Is It OK to Top Off Coolant With Water? When the pressure of the coolant in the radiator surpasses the designed pressure of the radiator cap, the antifreeze passes the radiator cap seal and flows into the coolant reservoir overflow tank through the overflow tube. When this coolant heats in the radiator, it begins to expand causing an increase in the pressure in the cooling system of that vehicle. The engine coolant absorbs the heat from the engine. When the engine is running at its optimum performance, it needs the engine coolant to keep it within the operational temperatures. The radiator overflow tank is fairly simple device but it can save you a lot of money by preventing rust from forming in the cooling system of your car. See Also: Losing Coolant But No Leaks (What to Do) How a Radiator Overflow Tank Works This saves you the expense of frequent coolant replacements and possibly the expensive cost replacing a radiator or other components of the cooling system. However, a radiator coolant overflow tank can prevent this problem before it even starts. When rust has formed inside the radiator, you will have no choice but to flush out the system and replace the antifreeze. That air will result in the formation of rust in the cooling system when it comes into contact with the metal in the system. Related: Overfilled Your Coolant?
