22353089 Pipe | Genuine Volvo Penta Part

🔧 Product Description

A genuine rigid coolant connection pipe installed in the expansion-tank and cooling-system connection group on selected Volvo Penta 16-litre industrial engines. It is formed to the factory routing so the expansion tank, hoses, clamps and cooling package remain correctly connected without hose strain or interference.

⚙️ Key Features

• Factory-formed rigid coolant pipe
• Part of the expansion-tank connection circuit
• Correct bends and connection positions for the original cooling package
• Supports secure hose clamping and controlled coolant return/vent flow
• Specified in later expansion-tank installations from the documented serial change
• Engine type: 16.1-litre, six-cylinder industrial diesel

🔌 Function

Routes coolant and air/return flow between the engine cooling circuit and expansion tank while maintaining the intended hose geometry and system sealing.

⚠️ Common Signs of Failure

• Coolant staining, seepage or drips at the pipe ends
• Corrosion, pitting or cracking in the pipe wall
• Progressive coolant loss or low expansion-tank level
• Air entering the cooling circuit or poor coolant recovery
• Overheating or unstable coolant level when leaks become significant

🛠️ Service Notes

• Offer the pipe up and check it reaches both connections freely before you tighten anything — a rigid pipe pulled into place is a pipe left under permanent strain, and strained pipes crack at the fittings in service
• Renew the sealing washers, O-rings or union seals that go with the pipe rather than reusing the old ones, and make sure the seats, faces and threads are clean
• Keep the ends capped while you work and blow or flush a pipe through before fitting; anything left inside goes straight into the oil, fuel or coolant system
• Tighten unions and banjo bolts evenly to the figures in the workshop manual for your engine — overtightening distorts the seat and starts the leak you were trying to cure
• Refit every clip and support bracket in its original place and keep the pipe clear of hot or moving parts so it cannot chafe or be shaken to failure
