A Heat Shield protects other parts from the heat generated by the engine. It is typically made of metal or ceramic materials and is installed between the engine and other sensitive components such as fuel lines or wiring harnesses. The Heat Shield's purpose is to prevent these components from overheating and potentially causing damage or safety hazards. It does this by reflecting and dissipating heat away from the surrounding area. Without a properly functioning Heat Shield, nearby components may be at risk of melting or becoming damaged due to excessive heat exposure.
