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.
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.
Contaminated fluids: The thermostat essentially works as a gateway for coolant that flows through the cooling system. Excessive contamination of that fluid can cause deposits around the thermostat, causing it to get stuck.
Yes, you can drive a car with a thermostat stuck open, but it's not ideal and could lead to several problems over time.
If this doesn't work, try resetting your thermostat with the reset button, changing the batteries, or cleaning off any dust and dirt inside. If the temperature is still stuck, an electrical or display issue might be to blame. Contact an HVAC professional for further help.
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.
The average cost of a new thermostat, including installation, ranges in price from $50 to $500 or more based on several factors including the type of thermostat, labor costs, the complexity of the installation, and more.
Turn your thermostat to the 'off' position... Then venture off to your home's breaker box. Find the breaker to your HVAC system, flipping it 'off'. Make sure the breaker is flipped all the way 'off,' then wait for 30-seconds. Turn the breaker back 'on.
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.
Overheating is the most common symptom of a failing thermostat. 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.
The Permanent Hold feature keeps your home's temperature at the same temperature indefinitely until you manually cancel it. If you can't reprogram your thermostat's temperature, this is likely the cause. You should be back on your programmed schedule as soon as you cancel it.
A thermostat leak is usually caused by movement in the coolant rubber hose, damaged housing, and a worn seal. The common symptoms of a thermostat housing leak are a stuck thermostat valve, an illuminated low coolant warning light, and the P0128 or P0125 code.
A lot of the problem is due to the similarity between issues with head gaskets and other engine components, such as the following: A chipped or warped cylinder head, which could affect the head gasket, but wouldn't necessarily be the result of a blown head gasket.
Conducting a compression test on each cylinder is a valuable diagnostic tool for identifying both a blown head gasket and a cracked block. Significant variation in compression levels between cylinders could indicate a blown head gasket, as the gasket's failure can affect the seal between cylinders.
One of the most common symptoms is an engine that runs poorly. It might have a rough idle, deliver poor acceleration, overheat, or exhibit a combination of all three issues. This happens because the engine makes less power as it loses compression.
It's not recommended to unplug the coolant temperature sensor unless necessary for diagnostic purposes, as it can adversely affect engine operation and potentially cause damage if left unplugged for an extended period.
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.
Installation typically takes about 1 hour.
If you drive with a bad thermostat, your car could overheat, causing severe and expensive engine damage. And while it's technically possible to drive without a thermostat, we don't recommend it. Your car will not reach an acceptable operating temperature, resulting in higher fuel consumption and excessive engine wear.
A car thermostat is designed to last a long time – typically around 100,000 miles or 10 years. However, various factors can impact its lifespan. First, driving conditions play a role. If you regularly drive in hot weather or stop-and-go traffic, your thermostat may suffer additional stress.
