When suspecting a mechanical seal is failing, checking the operating temperature is crucial because a mechanical seal is designed to operate within specific temperature limits. An increase in operating temperature can lead to thermal expansion and distortion of the seal materials, potentially causing failure. High temperatures may indicate issues such as improper lubrication, excessive friction, or even an overload condition, all of which can compromise the integrity of the seal. Monitoring the operating temperature can provide insight into the overall condition of the seal and help identify potential causes of failure before a complete breakdown occurs.

In contrast, while examining the tightness of the housing bolts, the level of vibration, and the fluid level in the reservoir can be important for diagnosing other equipment issues, they are not as directly indicative of mechanical seal integrity as operating temperature is. Each of those factors could contribute to operational problems but would not specifically highlight the condition of the seal itself.
