Description
Heat shield for Citroën and Peugeot vehicles with 1.4 VTi and 1.6 VTi engines.
Product Overview
This heat shield is designed for Citroën and Peugeot models equipped with 1.4 VTi and 1.6 VTi engines. It protects nearby components from excessive exhaust and catalytic converter heat, helps prevent heat-related damage to underbody panels, wiring and fuel lines, and reduces the risk of heat soak into the cabin. Robust and precisely shaped to fit factory mounting points, the shield restores proper clearance and reduces rattling when original shields have corroded or become loose.

Fitment and Compatibility
Intended for vehicles fitted with 1.4 VTi and 1.6 VTi petrol engines. Common applications include Citroën C3 Picasso, Citroën C4 II and Peugeot 308 models that use the listed part numbers. Always verify that the part number matches the one required for your vehicle when searching or ordering — this component is frequently located by OE code.
Installation Recommendations
- Work On A Securely Supported Vehicle: Use a lift or correctly rated jack stands on level ground before starting.
- Access And Removal: Raise the vehicle and locate the heat shield under the vehicle, typically mounted around the exhaust manifold or catalytic converter area. Remove corroded bolts or clips and take note of mounting orientation.
- Fasteners: Replace any seized or corroded bolts, nuts and clips with new OEM-equivalent fasteners to ensure secure fitment and prevent future rattles.
- Inspect Adjacent Components: Check exhaust hangers, catalytic converter brackets and nearby wiring or heat-sensitive parts for damage while the shield is removed.
- Tightening: Refit the shield to the original mounting points and tighten fasteners to the manufacturer’s specification. If torque values are unknown, consult the factory repair manual.
- Safety: Wear gloves and eye protection. Allow the exhaust to cool before working. If cutting or grinding is required to remove rusted studs, follow appropriate safety procedures.
Why This Part Fails
- Corrosion: Prolonged exposure to road salt and moisture commonly causes shields and their fasteners to rust through.
- Mechanical Damage: Impacts from road debris or contacting the road can deform or crack the shield.
- Fatigue And Loosened Mountings: Repeated heat cycles and vibration can break mounting tabs or allow fasteners to loosen, causing rattles.
- Exhaust Component Wear: A failing exhaust bracket or catalytic converter support can overload the shield and accelerate failure.
Search Tips
Customers and technicians often search by OE codes such as 758430880, 758430880-03 or by additional number 1723GS. Using these codes will increase the chance of finding the correct fitment quickly.
