A coupling member for coupling components within a coolant circuit includes a conduit having a first end configured to couple to a first component and a second end configured to couple to a second component, wherein, in use, a coolant fluid passes from the first component to the second component through the conduit. The coupling member further includes a sensor integral with the conduit and positioned between the first and second ends of the conduit, the sensor being configured to detect the presence of gas or air within the conduit.

A reservoir for a vehicle is provided. The reservoir is accommodated in a body formed by joining an upper case and a lower case to each other. A high-pressure reservoir space introduces and discharges coolant flowing from a high pressure cooling line and a low-pressure reservoir space introduces and discharges coolant flowing from a low pressure cooling line. A valve is also installed to maintain internal pressure of the high-pressure reservoir space and the low-pressure reservoir space constant.

Provided is fluid reservoir comprising a body having an inlet, an outlet, a fill aperture, and a fluid level indicator assembly. The fluid level indicator assembly is configured such at least an upper portion thereof extends external and above the body of the coolant reservoir. The fluid level indicator assembly includes a housing having a lower portion which extends into an interior volume of the body, and an upper portion, which is the portion that extends external and above the body.

A system is provided that may include a pressure sensor coupled to a radiator. The pressure sensor may determine plural pressure readings of a radiator fluid in the radiator. The system may also include a vehicle controller of a vehicle system that includes one or more processors. The one or more processors may repeatedly determine the plural pressure readings of the radiator fluid, and determine a pressure variance of the plural pressure readings that is repeatedly determined. The one or more processors may further be configured to identify a pressure condition based on the pressure variance that is determined.

The present disclosure relates to improved systems and methods for use in connection with maintaining the coolant system of a vehicle. Specifically, the present disclosure relates to improved systems and methods for monitoring the integrity of the coolant system in an engine, including capabilities for diagnosing leaks, degradation of coolant, open and/or loose radiator caps, and other sources of potential malfunctions. Early diagnosis and continuous monitoring of an engine coolant system results in earlier repairs and less vehicle downtime.
