20859385 Water Pipe | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta Formed Compressor Cooling Water Pipe - Part Number: 20859385

A genuine Volvo Penta rigid cooling-water pipe formed for the compressor and engine cooling circuit. The factory bends, connection geometry and support points route coolant around surrounding components while maintaining an unrestricted bore and correct clearance from hot, vibrating or moving parts.

Correct selection must be confirmed against the complete Volvo Penta product designation, product number and serial number because neighbouring engine variants can use different dimensions, connections, calibration or serial-controlled revisions.

🔌 Function

The pipe carries engine coolant through the compressor-related branch of the cooling system. Its internal diameter and routing are selected to provide adequate heat removal without creating a local restriction or trapping the pipe against adjacent hardware.

Common signs of failure:

• Coolant seepage at pipe ends or banjo-style connections

• Corrosion pitting, cracking or pinhole leakage

• Pipe flattened or restricted by impact or incorrect clamping

• Chafing where the pipe contacts nearby components

• Compressor or local cooling component running hotter than normal
