1257147 Heat Shield | Genuine Volvo Penta Part

🔧 Product Description

A genuine Volvo Penta injector nozzle-holder heat shield and sealing washer for Volvo D24-family indirect-injection diesel engines. The formed metal shield installs beneath the injector nozzle holder in the cylinder head. It protects the injector from combustion heat while forming the correct crush seal between the nozzle holder and the combustion chamber. A new shield should be installed whenever an injector is removed.

🔌 Function

The heat shield forms a thermal barrier that keeps radiated engine heat away from nearby components, hoses or wiring. It helps maintain safe surface temperatures in the engine bay and protects heat-sensitive parts from premature degradation.

⚠️ Common Signs of Failure

• Scorching, discolouration or heat damage on components that sit behind the shield
• Cracking, warping or burn-through of the shield itself
• Loose, missing or corroded fasteners allowing the shield to rattle or shift out of position
• Rattling or vibration noise from the engine area at certain speeds
• Deterioration of adjacent hoses, looms or insulation from direct heat exposure

🛠️ 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
