Vehicle owner experiences unexplained coolant loss when towing heavy loads over mountain passes, requiring frequent topping up and raising concerns about underlying cooling system issues.

No real-time monitoring or predictive tool to track coolant loss rate, distinguish normal from abnormal consumption, or diagnose root cause without manual observation and guesswork.

Workarounds Described

manually checks coolant reservoir at gas stops
watches temp gauge for fluctuations
carries extra coolant gallons on trips

Implied Software Gaps

Real-time coolant level monitoring with alerts for abnormal loss rate
Trip-level coolant consumption tracking correlated with driving conditions
Diagnostic assistant that distinguishes normal towing loss from system failure

App Concept

CoolantWatch Pro

A retrofit IoT sensor and app that continuously monitors coolant level and temperature, providing real-time alerts for abnormal loss, trends over trips, and diagnostic suggestions to prevent overheating and component damage.

Key Features

Wireless coolant level and temperature sensor with 10-year battery
Mobile app with trip heatmaps showing coolant level vs. load/grade
Predictive alerts for topping needs and leak detection
Trip logging with automated refill tracking and trend analysis

Target Users: DIY owners and small fleet managers towing heavy loads (RV, boat, equipment) with vehicles lacking factory coolant monitoring.

Revenue Model: $129 upfront for sensor kit + $4.99/mo app subscription for cloud storage/analytics
