⚙️ Key Features

🔌 Function

Shields nearby equipment and the engine space from the heat of the exhaust and turbocharger, holding surface temperatures down and protecting hoses and wiring.

⚠️ Common Signs of Failure

• Heat damage to adjacent hoses, wiring or paintwork
• Engine space running hotter than it used to
• Insulation found torn, oil-soaked or burnt through at its facing
• Ties or fixings broken so the insulation has moved off the component
• Scorched patch on a neighbouring part where cover has been lost

🛠️ Service Notes

• Two insulations supersede reference 21615533 at 0.343 kg and 0.351 kg - weight barely separates them, so order by part number
• Oil-soaked insulation is a fire risk: cure the leak before fitting new material
• Fit new ties and put the insulation back to its original coverage; a gap concentrates heat on what sits behind it
