There are a number of hoses under the hood of your Mercedes-Benz that you should be keeping an eye on. They are all important parts in your vehicle and responsible for a range of different jobs. There are several different types of cooling hoses, for example, that all help to regulate the temperature of your engine and other parts under the hood. You have upper and lower radiator hoses. The upper hoses is connected to your thermostat housing and radiator, while your lower radiator hose is attached to the radiator and water pump. You also have coolant and overflow hoses. The overflow hose will store overflow of coolant in the reservoir tank. It's important that you're checking hoses for wear and tear often to prevent more intensive damage. You can squeeze hoses to see if there is any degradation near the clamps. Clamps are used to secure your hoses over fittings and prevent leaking.
