20928485 Heat Shield | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta heat shield from the turbocharger and exhaust-manifold heat-shield assembly. It forms a thermal barrier between the hot turbocharger and exhaust surfaces and the rest of the installation, keeping radiated heat off the hoses, cables, fuel lines and belts routed nearby. The shield is formed for one specific location and must be matched to the engine and turbocharger arrangement.

🔌 Function

Shields the surrounding installation from radiated turbocharger and exhaust heat, protecting nearby hoses, cables, fuel lines and belts and reducing the fire and burn risk in the engine space.

⚠️ Common Signs of Failure

• Shield cracked, split or distorted around its fixing points
• Fixings loose, corroded or missing so the shield can move or rattle
• Scorched, hardened or melted hoses, cables or insulation close to the exhaust
• Shield touching a hose, cable or belt instead of standing clear of it
• Insulation, spacers or standoffs missing so the shield sits on a hot surface

🛠️ 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
