A coolant level probe 2-wire is a device that is used to measure the level of coolant in a vehicle’s cooling system. It is typically installed in the coolant reservoir tank. The probe has two wires that are connected to a sensor. When the coolant level is low, the sensor sends a signal to the vehicle’s computer, which turns on a warning light on the dashboard.
There are two main types of coolant level probes: float-type and capacitive. Float-type probes use a float that rises and falls as the coolant level changes. The float is connected to a switch that turns on and off as the coolant level reaches different levels. Capacitive probes use a capacitor to measure the coolant level. The capacitor changes its capacitance as the coolant level changes, which sends a signal to the sensor.
2-wire coolant level probes are typically used in older vehicles. They are less expensive and easier to install than 3-wire probes, but they are also less accurate. 3-wire probes use a third wire to send a ground signal to the sensor, which makes them more accurate and less likely to be affected by electrical interference.
Here are some of the benefits of using a coolant level probe 2-wire:
- It is a simple and inexpensive way to monitor the coolant level in your vehicle.
- It is easy to install and maintain.
- It can help you to avoid overheating your engine, which can lead to serious damage.
