20859426 Water Pipe | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta Formed Cooling Water Pipe - Part Number: 20859426

A genuine Volvo Penta formed water pipe for the engine cooling circuit. Unlike a universal hose, this rigid pipe uses fixed bends, end geometry and mounting positions to preserve coolant flow and component clearance in the original installation.

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 transfers coolant between the listed engine cooling components while maintaining the designed flow area. Its rigid routing also keeps the coolant connection stable so attached hoses and seals are not placed under side load.

Common signs of failure:

• Coolant leakage at the pipe ends or sealing joints

• Rust, pitting or stress cracking

• Distortion that prevents correct alignment

• Restricted flow from internal scale or impact damage

• Repeated hose or seal failure caused by a bent pipe
