Other Engine Bay Parts encompass a diverse range of components supporting core engine functions beyond major systems. These parts are located within the engine compartment and include items like coolant reservoirs, power steering fluid reservoirs, washer fluid reservoirs, and associated brackets/hardware. Technical features often involve high-temperature resistance in plastic components, corrosion protection on metal parts, and precise dimensional accuracy for secure mounting. Many utilize integrated sensors for fluid level monitoring or incorporate quick-connect fittings for simplified servicing. Replacement is typically dictated by damage, leaks, or failure of integrated sensors, necessitating component-specific diagnostics.
