21866946 Heat Shield | Genuine Volvo Penta Part

🔧 Product Description

A genuine position-specific heat shield fitted around the exhaust manifold on Volvo Penta TAD1670-72VE industrial engines.

🚤 Compatibility

Typically suits:

• Volvo Penta TAD1670-72VE

• Engine Family: TAD
• HP Range: Approximately 500-800 HP
• Year Range: Approximately 2010 - 2021

⚙️ Key Features

• Genuine Volvo Penta position-specific thermal shield
• Factory shape and mounting-hole pattern
• Reduces radiant heat exposure
• Protects wiring, hoses and nearby components
• Designed for engine vibration and repeated heat cycles
• Engine type: 16.1L inline six-cylinder turbocharged industrial diesel

🔌 Function

Forms a thermal barrier between hot exhaust or turbocharger components and the surrounding engine installation.

⚠️ Common Signs of Failure

• Cracking, warping or corrosion
• Rattling from loose mountings
• Missing spacers, bushings or fasteners
• Contact with the exhaust or turbocharger

🛠️ Service Notes

• Fit heat shields before anything else is routed near the exhaust, and check there is clear air space between the shield and every hose, cable, fuel line and belt
• Renew any insulation, gaskets, spacers or standoffs supplied with the shield; a shield clamped flat onto a hot surface loses much of its effect
• Tighten the fixings evenly and only to the figure in the workshop manual for your engine — the tabs and brackets are thin and distort easily
• Never run the engine with a shield missing or loose: bare exhaust surfaces are a fire risk in an engine space and a burn risk to anyone working alongside
• Check the shield and its fasteners whenever the exhaust is disturbed, as vibration works them loose and a rattling shield soon cracks at its mounting tabs
