What This Product Does

This pipe forms part of the engine coolant breather circuit. It provides the connection used by that circuit within the cooling system.

Technical Details

• Brand: OE Match.
• Component identification: cooling water breather pipe / breather line.
• Engine identifiers recorded for this part in the supplied diagram: 4620, 4640, CWAA and CXNA.

Symptoms of Fault

• Moisture or dried coolant deposits around pipe connections.
• A sweet coolant odour following a journey.
• Coolant level falling between checks.
• Visible damage or leakage from the pipe or its fittings.
• Temperature increases or coolant warnings associated with coolant loss.

Why Replacement Matters

A damaged breather pipe or leaking connection can allow coolant to escape. Renewing a confirmed faulty component addresses the leak; inspecting adjacent connections at the same time helps identify other sources of seepage. These symptoms can also originate elsewhere in the cooling system, so diagnosis should precede replacement.

FAQs

How should a suspected leak be checked?
Inspect the pipe and connection points for dampness or deposits. A cooling-system pressure test can help locate leaks that are difficult to see.

What should be checked before selecting this pipe?
Confirm the vehicle's engine identification and compare reference 94610602622 with the component being replaced.
