What to check before you buy
- Unscrew the oil filler cap and look directly inside with a flashlight at the top of the belt (visible immediately beneath the cap) for fraying, fuzzy texture, or micro-cracks
- Scan for P15A1/P15A8, P0011, and P1336
- Test brake pedal firmness during a hard stop as a specific check for vacuum pump health, independent of any engine symptom
- Treat 'Low Oil Pressure'/'Stop Engine' warnings during cornering or braking as belt degradation, not a sensor glitch
