Honda Insight Low Water Sensor Replacement at your home or office.

What is the Low Water Sensor all about?

Your engine needs coolant in order to maintain an optimum operating temperature. If the temperature exceeds a threshold, serious damage can occur. In order to ensure that optimal temperature is maintained, you need the right amount of coolant in the radiator, reservoir, and engine. Leaks will result in low levels of coolant, which will be detected normally by low water sensors (or, more accurately, coolant level sensors).

The low water sensor doesn’t track the level of coolant in your engine or the radiator. Instead, it works as a thermistor, which uses relative temperature difference to determine the amount of coolant flowing through the engine during operation. The temperature difference information is sent from the low water sensor to the car’s computer, where it is used to determine whether there is sufficient coolant or not. If the computer determines there isn’t enough coolant, it turns on a warning light in the dash (the actual light will vary from one automaker to another, so consult your owner’s manual).
