21087678 Charge Air Pipe | Genuine Volvo Penta Part

🔧 Product Description

A genuine Volvo Penta rigid charge-air pipe used in the early TAD732GE/TAD733GE radiator/intercooler cooling package. The pipe carries compressed air between the turbocharger, intercooler and inlet tract through the engine-specific routing shown in the early cooling-system arrangement. Its bead, sealing-end geometry and mounting points are designed for the original clamps, O-rings and support hardware.

🚤 Compatibility

Typically suits:

• Volvo Penta TAD732GE EDC4
• Volvo Penta TAD733GE EDC4

• Engine Family: TAD

⚙️ Key Features

• Rigid boost-air pipe for the early TAD732GE/TAD733GE cooling package
• Correct diameter and smooth bore preserve charge-air flow
• Formed routing aligns with the original intercooler and inlet connections
• Beaded or machined ends retain the specified seals and clamps
• Must be checked for the early serial-range cooling-package configuration
• Engine type: D7-series turbocharged generator diesel with air-to-air intercooler

🔌 Function

Transfers compressed intake air through the intercooler circuit with minimal pressure loss, preserving boost pressure and reducing charge temperature before the air enters the engine.

⚠️ Common Signs of Failure

• Oil mist or soot staining around a charge-air joint
• Boost leak and reduced engine power
• Black exhaust smoke under load
• Cracked pipe or damaged sealing bead
• Whistling or hissing during boost

🛠️ Service Notes

• Clean both sealing faces before assembly and check the rubber sleeves, seals and clamps; hardened, swollen or split sleeve rubber will not hold boost on a new pipe
• Seat the pipe fully onto its spigots and set each clamp behind the bead before tightening, so pressure cannot push the joint apart
• Align and support the pipe on its brackets so it is not pulled into tension — a pipe held under strain chafes, cracks and works its clamps loose
• Check the bore for oil sludge and soot before fitting and clean it out; carried-over oil softens sleeve rubber and blackens a new pipe from the inside
• Tighten clamps and any flange fasteners to the figures in the workshop manual for your engine, then re-check them after the first run under load
