Recommendations:
- Review Historical Data: Analyze the engine’s operational data to track the frequency and circumstances of the low-pressure readings.
- Detailed Inspection and Testing: Perform a detailed inspection and functional testing of the coolant system, focusing on detection of intermittent issues.
- Address Identified Problems: Make repairs or adjustments as required based on diagnostic findings.
- Monitor System Performance: Continue monitoring the coolant system closely after repairs to ensure stability and adequacy of the repairs.
