The degas tank is located in the right side of the engine compartment. The tank is located by a grommet on its underside and positively secured with a bolt and washer to a bracket on the vehicle body and a second bracket that locates in a molded slot in the tank body.
The degas tank has 2 connections; one for coolant expansion via the radiator overflow and one for coolant inlet into the thermostat housing. The overflow pipe is secured in the tank with a plastic clip. The hose to the thermostat housing is a quick release connector, retained with a spring clip.
A coolant level sensor is located in the underside of the tank body. The sensor reacts to the influence of a magnetic field. A float, with integral magnet, is located inside the tank, over the sensor tube. The sensor has contacts inside the tube, which are normally open. When the fluid level reduces, the magnetic float moves down the tube. When the magnet reaches the sensor contacts, the magnetic field closes the contacts. The sensor is connected to the CJB (central junction box) which receives the signals from the sensor. Maximum and minimum marks are molded on the tank body.
The degas tank provides the following functions:
- Service fill
- Coolant expansion during warm-up
- Air separation during operation
- System pressurization by the filler cap.
