OE-style vacuum elbow connector that joins the check valve to the intake manifold and replaces brittle or cracked original fittings.
$5.87
The 058 133 394D elbow connector is a molded vacuum-hose connector that joins the check valve to the intake manifold in the applicable engine vacuum system. Its angled design routes the vacuum connection correctly while maintaining a sealed path between components.
Plastic vacuum connectors operate in a high-temperature engine environment and can become brittle over time. Heat cycles, oil vapor, and weather exposure may cause cracking, splitting, or broken connection points that lead to vacuum leaks.
A sealed vacuum system is essential for stable engine operation. When this connector develops a crack or fails to seal, unmetered air can enter the intake tract. As a result, the engine may idle roughly, run inconsistently, or store fault codes that illuminate the check-engine light.
Replacing a damaged connector helps restore the intended vacuum path between the check valve and intake manifold. It is also wise to inspect the related vacuum hoses and check valve during service, since these components are exposed to the same heat and age-related wear.
Inspect the vacuum connector and connected lines if you notice:
Rough or unstable idle.
Hissing sounds from the engine bay.
Check-engine light with vacuum or lean-mixture fault codes.
Visible cracks, splits, or broken connector ends.
Loose vacuum-hose connections.
Reduced engine response or inconsistent performance.
Similar symptoms can result from other vacuum-system faults. Inspect all connected hoses, seals, and check valves before replacing parts.
