⚙️ Key Features

• Approximate weight: 2.943 kg
• Heavy formed exhaust heat shield
• Application-specific shape and mounting points
• Protects nearby components from radiant heat
• Supplied as an individual shield section

🔌 Function

The panel reduces heat transfer from the turbocharger and exhaust system.

⚠️ Common Signs of Failure

• Cracking or delamination
• Loose or broken mounting tabs
• Rattling against exhaust components
• Heat damage outside the insulated area

🛠️ Service Notes

• Refit every shield and insulation panel before the engine is run — they are there to keep exhaust and manifold surface temperatures down in an enclosed engine space, and leaving one off is a genuine fire risk as well as making the space unbearable
• Check that the standoffs, spacers, clips and fasteners go back with the panel; the air gap they hold is what does the insulating, so a panel clamped flat to the manifold is not doing its job
• Renew insulation that is charred, crushed, torn, delaminated or has been soaked with oil or fuel — once contaminated it cannot be cleaned and it becomes the ignition source it was fitted to prevent
• Find and fix the leak first if the old insulation was oil-soaked or fuel-soaked; a new panel fitted over a live leak will be ruined again
• Check clearance to hoses, cables and the wiring loom once refitted, and make sure nothing can chafe against the shield edge with engine movement
