What happens if I don’t replace my coolant level sensor?
A bad coolant level sensor could cause your engine to
overheat
. Without proper coolant, you could face engine damage and even engine block failure, so it’s important to replace your coolant level sensor immediately to avoid more costly repairs down the road.What is a coolant level sensor?
The coolant level sensor, as its name suggests, measures the coolant or antifreeze level in the radiator. The sensor is an electric component attached to the radiator—or in some vehicles inside the radiator—that notes when your vehicle has a low coolant level. It’s an essential component of the coolant system in your vehicle.
The coolant sensor will set off a check coolant light—or the check engine light in some vehicles—to inform you when your coolant level is too low.

- The warning light is on even if the reservoir is full of coolant.
- The warning light is not on even when coolant levels are too low.
How often should a coolant level sensor be replaced?
There is no determined mileage or age limit for your vehicle’s coolant level sensor, but they can malfunction or wear out due to corrosion. You should watch for warning signs of a faulty coolant level sensor and take your vehicle to a mechanic if you suspect you need a replacement.
Can I replace my coolant level sensor myself?
If you have a lot of experience with DIY auto repair, you can learn how to replace a coolant level sensor at home. However, if you’re not confident in your skills, you could end up creating a worse problem.
To ensure the job is done right, take your vehicle to a professional to replace your vehicle’s coolant level sensor.
