Automotive guides

Brake lining is friction material; a brake line carries hydraulic fluid. Learn the difference between linings, pads, shoes, rotors and hose repairs.

Understand dexos1 Gen 3, dexosD, dexos2, and dexosR. Match the correct GM oil requirement and viscosity, then verify the actual product license.

LOAD PCT usually means calculated engine load. Identify the PID, separate it from throttle and absolute load, and compare readings under matched conditions.

Understand what an OBD2 scanner reads, how it differs from the car’s onboard diagnostics, and why a trouble code is not a parts diagnosis.

Read spark advance in its timing reference and operating context. Understand BTDC and ATDC without treating scanner data as a timing adjustment.

Understand the difference between 5W-20 and 5W-30, compare real product data, and check whether your engine permits substitution before changing oil grades.

Find the exact bracket-to-knuckle torque by vehicle and brake package. Check bolt renewal, thread condition, units and tightening stages before assembly.

TP usually means throttle position. Distinguish absolute, relative, commanded and pedal readings before judging percentages or replacing parts.

Choose caliper-pin lubricant by the brake design and rubber compatibility. Learn when pins run dry, what labels mean and why excess grease causes trouble.

No verified Honda-wide micron figure is established here. Learn how to check a specific filter using efficiency, particle size, test method and application.

Asbestos was replaced by engineered friction blends, not one universal ingredient. Understand NAO, ceramic and metallic pads, plus precautions for old brakes.

Understand injector electrical supply, controller switching and fuel pressure, including why a universal 12-volt wiring rule can mislead.
