If you ignore this problem, it will undoubtedly cost you more in engine repair than it would to replace the thermostat. Replacing a Failed Thermostat in a VolkswagenĪ thermostat replacement is a relatively inexpensive repair. This leak is a sign of a faulty thermostat in your car, not the cause. Coolant Leak: You’ll notice coolant leaking around the thermostat casing as pressure develops around a defective thermostat that is stuck shut.Even if the thermostat is open, water will not circulate through the car’s cooling system when it goes bad. Water Pump: The water pump is in charge of moving coolant via the radiator to the engine.Bad Radiator: Your car will overheat if the radiator has become clogged to the point where coolant cannot efficiently move through it.Low Coolant: If you’ve been losing coolant in your car, you may have finally spilled out enough that the cooling system can’t keep up.However, other factors that can make the temperature gauge increase include: The warning lights might come on due to the malfunctioning thermostat. If you observe this, pull off somewhere safe and turn off your car engine as quickly as possible to avoid any further harm to your engine’s parts. Most VW owners will notice an engine warning light or a raised temperature gauge as the first indicator of a failing thermostat. Causes of an Engine Warning Light or Temperature Gauge Spike This will be a rapid response after you turn on the engine. When this happens, the coolant cannot circulate throughout the engine’s hottest parts. The thermostat is most likely stuck in the closed position, and the coolant is prevented from entering the engine as a result of this. One of the most common indications of a malfunctioning thermostat is when the engine overheats. When the valve is stuck open, the coolant runs through without varying and your engine will run too cold to function properly.

Hopefully, you will discover your malfunctioning thermostat before this malady occurs. Unfortunately, the process of replacing a head gasket is time-consuming for mechanics and is, therefore, expensive. Rough idling, water in the oil, poor fuel mileage, and plenty of white smoke from the exhaust are all signs of a blown head gasket. The head gasket can blow/crack if you drive your car for a long distance while there is no coolant flowing through it. Your car will alert you to the fact that your thermostat is malfunctioning in one of several ways, either by the check engine light or by one of the following symptoms: A Blown Head Gasket A burst head gasket, a spiking temperature gauge, and other signs of a malfunctioning thermostat are typically easy to recognise. When your VW’s engine thermostat malfunctions, you’ll encounter different kinds of issues with your car. However, it is also susceptible to wear and tear since it is in constant use every time your engine is on. It’s a simple part which performs an extremely important duty. When the engine is cold, the thermostat shuts to enable it to heat up, and it gradually opens as the engine warms up, allowing fluid to reach the radiator. It controls the flow of coolant between the radiator and the engine. The thermostat in your Volkswagen regulates engine temperature and is an essential component of your vehicle’s cooling system.
