Built by Marcus Sanders of Chevy Suggestions. His 2004 Chevrolet Suburban 1500 needed a radiator, so he made a free app that helps Chevy owners diagnose problems and fix them step by step — real photos beside every step, the tools you'll need (and where to borrow them free), budget parts lists, and a Parts Finder that checks whether a part number actually fits your year, model, and engine. No account. No cost. Nothing to buy.
Diagnose by symptom, or look up OBD-II codes (including GM-specific ones)
12 step-by-step repair guides with photos — radiator, hydroboost, brakes, water pump, alternator, starter and more, starting with 2000–2006 GMT800 trucks
Tools-needed lists with pictures, free loaner-tool tips, and budget parts lists with DIY vs shop prices
Parts Finder: check a part number against your exact vehicle before you order
Save your vehicles and repairs in your own garage (stored only on your device)
A Coverage Helper that logs repairs and codes not yet covered, so they get added
