They will be able to inspect your vehicle and determine if your car will need a replacement coolant level sensor. Sometimes they get stuck, & a screw driver will help pry them back. Once you get the 3 bolts out, pull the clips on the hoses & pull them back. For this reason, if you suspect that your coolant level sensor may be having an issue, have the vehicle diagnosed by a professional technician, such as one from YourMechanic. The coolant expansion tank is a very easy install. While the coolant level sensor doesn’t play a big role in engine performance or drivability, it does serve a very specific purpose in protecting the engine from dropping low in coolant and potentially overheating. If the coolant level drops low enough to cause overheating, and the low coolant light is not illuminated beforehand, then that may be an indicator of a problem with the sensor. Eventually, the coolant fluid reaches a boiling point, increasing the pressure within the system. We have a great choice at very good prices. Radiator Radiator cap or pressure cap Thermostat valve Water pump Upper and lower hose As the coolant circulates through the engine compartment, it absorbs the heat produced by the engine. Browse our website for one that fits your car. However, if the overheating is related to coolant level, this may be an indicator of a problem with the sensor. Home Car Parts Cooling & Heating Cooling Expansion Tanks Expansion Tanks A damaged expansion tank the tank used to conserve coolant - can cause leaks, and should be replaced at the first sign of wear. Engine overheating can be caused by a variety of issues, usually not related to any sensors. The engine overheating is another indicator of a problem with the sensor. The sensor is designed specifically to detect low coolant, so if the level in the reservoir drops low, and the light does not come on, that may be an indication of a problem with the sensor or perhaps the wiring. If the coolant level drops low and the light does not come on then that means the sensor or wiring are having a problem. Low coolantĪnother symptom of a problem with the coolant level sensor is low coolant. This is a problem because a permanently illuminated coolant light will not be able to properly alert the driver if the coolant level does drop low. If the sensor shorts, it can cause the Coolant Level Light to stay on. One of the most common symptoms of a faulty coolant level sensor is a Coolant Level Light that stays on. Low coolant is dangerous to the engine as the coolant is what keeps the engine from overheating during normal operation, so it is imperative to replace the coolant level sensor if it is failing. Two marks on the overflow tanks indicate the minimum and maximum levels. Just have dealer top it off during next oil change. As long as the expansion tank has coolant i wouldnt sweat it. Its not unreasonable that the factory didnt fully burp the system. When the level drops below a safe level the low coolant light will come on to alert the driver that coolant must be added. The reservoir is part of the pressurized system.It is usually installed in the coolant reservoir or radiator, and measures the amount of coolant in the system to make sure that it is always at the proper level. The coolant level sensor is the electronic sensor that is responsible for measuring the coolant level of your engine.
