CoolantIQ

CoolantIQ is a mobile app that connects to OBD-II and aftermarket pressure sensors to diagnose elusive cooling system issues like highway-speed overpressure or towing-related coolant loss. It uses anomaly detection algorithms to identify root causes—such as combustion leaks or restricted flow—when standard scan tools show no codes. Unlike generic OBD readers, it offers tailored diagnostic workflows and parts-problem correlation for technicians and DIYers.

Key Features
  • Real-time coolant pressure/temperature monitoring with predictive alerts
  • Anomaly detection engine for intermittent overpressure events
  • Step-by-step guided diagnostics for specific symptom patterns (e.g., highway overpressure, towing loss)
  • Coolant color analyzer using phone camera and database correlation
Target Users: Professional automotive technicians and advanced DIY car owners
Revenue Model: Freemium with monthly subscription for advanced diagnostics and historical data; one-time purchase for hardware pressure sensor kit.
