Intermittent coolant leak near water pump on a 1999 Ford Ranger V6, returning 3 years after replacement, with no clear diagnosis

Workarounds Described

• adds UV dye to coolant and visually inspects with a UV light
• replaces parts speculatively (water pump, hoses) hoping to fix leak
• observes leak intermittently over months to infer patterns

Implied Software Gaps

• Automated pressure decay logging and leak pattern analysis would replace manual UV dye inspection
• Vehicle-specific failure databank would reduce speculative part replacement
• Persistent monitoring system would capture intermittent events without owner observation

LeakTrace Pro

An app that pairs with a Bluetooth pressure sensor and UV dye camera to log pressure drops and leak patterns over time. It uses AI to pinpoint intermittent leak sources and suggest targeted repairs, eliminating guesswork and repeat replacements.
