⚠️ Common Signs of Failure

• Cracked, brittle or missing insulation
• Heat damage or discolouration on nearby components
• Loose insulation contacting moving parts
• Higher engine-compartment temperature
• Soot staining or damage around an adjoining exhaust leak

🛠️ 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
