Contaminated Coolant: Coolant contamination can result from using the wrong type of coolant, mixing coolants, or not changing the coolant regularly. Contaminants can cause the thermostat to stick or become corroded, leading to its malfunction.
Due to corrosion or aging, your car's thermostat can get stuck in a closed position. If this happens, the thermostat will not let the coolant reach the radiator, and, as mentioned above, the engine will overheat, causing severe damage. One of the lesser-known issues is the polar opposite of overheating.
A car thermostat typically lasts between 10 to 15 years, or about 100000 to 150000 miles, depending on the vehicle and driving conditions. However, factors like engine temperature, coolant quality, and maintenance practices can affect its lifespan.
Power problems are one of the most common causes of thermostat failure. Whether your thermostat is wired to the mains or runs on batteries, a lack of power will stop your thermostat from accepting commands and communicating with your HVAC system.
No, it is not okay. One of two things will happen. Either the engine will never warm up to normal operating temperature, or the water will flow through the radiator so fast that it will not stay in the radiator long enough to cool down, which will actually make your engine overheat.
The average cost for car thermostat replacement is $661 to $747. Enter your vehicle's information to see how much thermostat replacement costs in your local area.
Corrosion occurs, among other things if a wrong coolant is used. The corrosion attacks the thermostats aluminum parts that almost "etch away" (see figures 1 and 2). But also mixing of different coolants can cause corrosion. Therefore avoid mixing different types of coolant together.
The Lifespan of a Thermostat
On average, most thermostats last about 10 years, depending on the model, usage, and proper maintenance. However, many people decide to replace their unit sooner to take advantage of new energy-saving technologies.
The thermostat is responsible for regulating the temperature of the AC system. If the thermostat is not working properly, it won't be able to regulate the temperature properly, which will cause warm air to be blown into your car.
This can happen if there is a power surge or if the thermostat is connected to a faulty electrical circuit.
Car thermostat replacement time is 30 to 60 minutes, depending on the make of the car. It will cost you around $190 to $350, including labor. Thermostat repairs usually take more time, requiring extra time to diagnose and analyze the vehicle's thermostat. It can take up to 2 hours.
While there is a small chance that there is an issue with the running temperature of your engine, by far the most common issue with trouble code P0128 is a faulty thermostat. The exact location of the thermostat and issues related to a damaged thermostat may vary depending on your vehicle.
A high reading on the temperature gauge could mean any number of problems from a coolant leak, a water pump malfunction, or broken thermostat gauge. It could be displaying an inaccurate temperature. In this case, your car may not be overheating, but your temperature gauge won't be able to warn you.
This is an easy problem to solve yourself by simply removing the plastic outer casing and, with a very soft brush, delicately brushing off its coil and contact surfaces. It is most effective to clean the thermostat first at its lowest setting, then again at its highest setting.
Blown head gaskets can happen when an engine severely overheats due to a faulty thermostat, clogged radiator, leaking water pump, radiator, radiator hose or heater hoses or when the coolant in the cooling system is not changed per the O.E.M.'s scheduled maintenance.
Temperature Fluctuations: One of the most common signs of a bad thermostat is erratic temperature readings on your dashboard gauge. If you notice that the temperature gauge moves from normal to hot quickly or fluctuates unexpectedly, it's a clear indication that your thermostat may be malfunctioning.
Absolutely. While it may seem like a small part of your HVAC system, the thermostat plays a crucial role in ensuring your home stays cool and comfortable. If you're experiencing issues with your AC not cooling properly, checking the thermostat should be one of your first steps.
It could be a number of issues, such as refrigerant leaks, faulty compressor or compressor clutch, blocked air vents, faulty thermostat, broken cooling fans, a blown fuse, electrical problems, a broken condenser and blower motor issues.
The furthest you can drive an overheating car is about a ¼ mile before you risk irreversible engine damage. While some vehicles could still make it as far as 20 miles, we would never recommend driving very far with an overheating engine.
Thermostats, like many other electrical appliances, will malfunction if they're allowed to get too dirty. Dirt, dust, and debris can pose problems for both electrical and mechanical components, causing your thermostat to fail.
In most cases, installing a new thermostat is a relatively simple do-it-yourself project that can result in improved comfort and convenience and one that can help you save energy.
Generally, repairing a thermostat costs around $200 to $500. This is the price range you'll find for most vehicles, although some may be higher or lower depending on the circumstances. But if we're talking complete replacement, expect the price to increase by $50.
Place the thermostat in a pot of water on the stove. Turn on the heat and use a thermometer to monitor the water temperature. As the water heats up, observe the thermostat. It should start to open around the specified temperature (usually marked on the thermostat).
