Car engine temperature fluctuates from normal to overheating (90°C to 120°C) cyclically, despite replacing multiple cooling system components and verified no coolant loss.

Standard diagnostic tools show temperature values but cannot pinpoint the root cause of cyclic overheating after multiple component replacements; mechanics are guessing without clear guidance.

Implied Software Gaps

An AI diagnostic system that synthesizes all repair history and live data to suggest the most likely remaining causes

App Concept

OverheatPro Diagnostic Assistant

An AI-driven diagnostic tool for automotive cooling system issues. It analyzes live sensor data, vehicle history, and symptom patterns to recommend specific tests or repairs, reducing guesswork. The app guides mechanics step-by-step through complex thermal faults, even intermittent ones.

Key Features

Real-time temperature data logging and graphing
Diagnostic tree for cyclic overheating based on symptom patterns
Component replacement history tracker with success/failure feedback
Integration with common OBD2 scanners for deep data analysis

Target Users: Independent car owners and small auto repair shops dealing with persistent cooling system problems

Revenue Model: $9.99 per diagnostic report or $29/month subscription with unlimited reports and priority support
