Īs a safety measure, you could replace your existing thermostat when your vehicle’s cooling system components are serviced. So, most mechanics recommend a thermostat replacement after 10 years. Here are the different types available for your car:Ī car thermostat does eventually wear down and fail. Vehicle thermostats may be either mechanical or digital. What Are The Different Types of Thermostats? This keeps the engine at an optimal temperature (between 195☏ to 225☏), preventing overheating. When the engine hits a certain temperature (usually around 195☏), the valve opens, allowing the radiator to cool the liquid coolant. This, in turn, promotes efficient fuel use and reduces engine deposits. It traps the engine heat, helping it quickly heat up to the right temperature. When you start your car, the thermostat valve is closed, preventing the coolant flow from reaching the radiator and cooling the engine. It’s an important part of your vehicle’s cooling or heating system or HVAC system, helping regulate the temperature setting of the vehicle. The thermostat helps keep your engine running at the right temperature. If something goes wrong, get it replaced as soon as possible.Here are quick answers to four questions about thermostats and their replacement: 1. It can overheat and seriously damage your engine, so it’s not something to play around with. They will last over 150,000km in the right conditions. They typically won’t fail unless there’s contaminants in the coolant or you use water instead of coolant. How often do I need a thermostat replaced? There’s a fair bit of labour involved for such a small part. How much does a thermostat replacement cost? They will then run the engine up to temperature and test the system. They will then reconnect any wiring or sensors and refill the coolant. They will then test the new thermostat and install it with a new gasket. After draining the coolant, they will unbolt and remove the thermostat as well as its gasket and clean the mounting surface. The mechanic will first locate the thermostat housing and disconnect any wiring or sensors attached to it. What’s involved in getting a thermostat replaced? These indicate that the thermostat is stuck closed. Other key indicators are that the engine overheats quickly or that you struggle to get hot air through your vents. If your engine takes a long time to get up to temperature then it may indicate that the thermostat has failed. It does a neat job and it’s a critical part of your engine. As the motor increases in temperature the thermostat opens more and more to manage the temperature and keep the right amount of coolant flowing. This helps extend the life of your motor. This helps warm the motor up slowly and bring everything up to the right temperature. The thermostat stays closed when you cold start your car. At higher temperatures it opens up and allows unrestricted flow to move all the available pressure through the system and cool the engine down. At lower temperatures it stays closed and restricts the flow of coolant through the car. Think of it as a halfback, it’s small, manages a whole bunch of components and can cause headaches if it stops doing its job.Ī thermostat is either a mechanical or electric valve that's found on the inlet set side of the engine's cooling system. The thermostat helps to do a whole bunch of important things in your cooling system.
