The engine in your Volkswagen gets hot when you're going from place to place. This is why you have an entire cooling system at work to help regulate the temperature of your engine. You don't want it to overheat - it can cause a ton of problems and also prevent you from driving your vehicle. The cooling system consists of a range of parts that include a water pump, radiator hoses, a cooling fan, and the radiator itself. The radiator helps your engine to maintain the perfect temperature balance so it can run as efficiently as possible. It works to send coolant back and forth to the engine when needed. If your engine gets too hot, it will send more coolant, and if it isn't quite warmed up enough, it will work to prevent coolant from getting through. It's important to check the condition of your radiator often so you can make sure it hasn't become damaged or worn. If it has, you might notice cracks or holes that have caused coolant to leak underneath your car. You could also notice your engine temperature spiking soon after you turn it on. Ensure you get an OEM replacement radiator if yours has worn out so it will fit your Volkswagen. Find the right one here on our site along with other cooling system parts.
