A practical 7-step checklist for evaluating automotive parts suppliers, written by a quality inspector at Optimal. Use it before approving stamping, CNC, forging, and extrusion suppliers.
A failure analyst at Optimal shares lessons from 24 documented manufacturing mistakes—covering optimal thermostat settings in winter, alternator chargers, coating piston skirts, and what car air filters really do.
The differential fluid interval is 30,000-60,000 miles for normal use, but severe use moves it to 15,000-30,000 miles. This checklist also explains optimal transmission fluid temperature, changing home air filter reminders, and Pep Boys alternator considerations.
A scenario-based sourcing guide from a procurement manager's perspective: choosing between original restoration parts, custom stamped components like modern radiator covers, recurring consumables like a 4 air filter, and understanding the difference between alternator and generator.
