If the thermostat is not working correctly, it can cause the coolant to overheat and bubble. This can lead to engine damage or failure.
A thermostat is a key component to keeping your car’s engine cool. If it isn’t functioning properly, it can cause the coolant to overheat and bubble. This can lead to major engine damage and should be fixed as soon as possible.
Coolant Reservoir Boiling But Engine Doesn’T Overheat
If your coolant reservoir is boiling but your engine isn’t overheating, there are a few possible explanations. Perhaps the most likely explanation is that your thermostat is stuck open. This would allow coolant to circulate through the engine without ever reaching operating temperature, causing the coolant to boil in the reservoir.
Another possibility is a leak in the cooling system that is allowing coolant to escape before it can reach the engine. Finally, it’s also possible that the water pump isn’t circulating coolant properly, causing it to overheat in the reservoir. Whichever of these problems you’re experiencing, it’s important to get it fixed as soon as possible because an overheated engine can cause serious damage.

Would a Bad Thermostat Cause Coolant to Boil?
A thermostat is a component in your car that regulates the flow of coolant to the engine. A bad thermostat can cause coolant to boil. When coolant boils, it produces steam, which can lead to engine damage.
Can a Bad Thermostat Cause Coolant Bubbling?
When your car’s thermostat starts to go bad, it can cause the engine to overheat. This can cause the coolant to start boiling and bubbling. If this happens, it is important to have the thermostat replaced as soon as possible.
If the problem is not fixed, it could lead to serious engine damage.
What Causes Coolant to Bubble?
One of the main causes of coolant bubbling is a leak in the cooling system. When there is a hole or crack in the radiator, water pump, hoses, or any other part of the system, it can cause coolant to leak out. This loss of coolant can cause the engine to overheat, and as the temperature rises, the coolant will start to boil.
The pressure from the steam can then force its way through any weak spots in the system causing bubbles. Another common cause of bubbling coolant is a build-up of air pockets. These air pockets can be caused by many things such as a low level of antifreeze, an incorrect mix of water and antifreeze, or even just not bleeding the system properly when changing the coolant.
If these pockets of air are not removed, they will eventually make their way into the heater core and Radiator causing them to bubble up when heated.
What are the Symptoms of a Bad Coolant Thermostat?
If your car’s coolant thermostat isn’t working properly, it can cause a number of issues. Here are some common symptoms of a bad coolant thermostat:
1. Overheating Engine
One of the most obvious signs that something is wrong with your coolant thermostat is if your engine starts to overheat. If the thermostat gets stuck in the “open” position, it will stop regulating the flow of coolant and your engine will start to overheat.
2. Coolant Leaks
Another symptom of a bad coolant thermostat is leaks. If the gasket or seal on the thermostat fails, it can allow coolant to leak out. You might notice a pool of greenish-yellow liquid under your car when it’s parked, or you might see steam coming from under the hood while you’re driving.
Either way, it’s important to get this fixed as soon as possible as continuing to drive with a leaking cooling system can lead to even more serious problems.

Conclusion
The blog post discusses whether or not a bad thermostat can cause coolant to bubble. The author states that a thermostat regulates the flow of coolant in a engine, and if it is not working properly, it could cause the coolant to boil. The author goes on to say that if the thermostat is stuck open, it will not allow the coolant to circulate properly and this could cause the engine to overheat.
