C3 1969-1978 Corvette Radiator Support/Shroud Seal Fastener - Push-In Type

Maintain the integrity of your C3 Corvette’s cooling system with the Pus-In Type Radiator Support/Shroud Seal Fastener, precisely designed for 1969–1978 Chevrolet Corvette models. This component is the essential OE-like solution that keeps the radiator shroud securely in place while preserving a tight, debri-free seal at the core support interface.

Why this fastener matters

• Directs airflow where it matters — a snug seal around the radiator shroud ensures cooling air moves through the core as intended, helping your engine reach and sustain optimal temperatures even in demanding conditions.
• Reduces vibration and movement — a secure pus-in fastener minimizes rattles and shift during highway driving and engine operation, protecting the shroud and surrounding cooling components.
• Designed for authentic restoration — engineered to fit the factory mounting points on C3 Corvettes from 1969 to 1978, supporting proper alignment and fit without aftermarket guesswork.
• Simple, too-free installation — the pus-in design enables quick, clean mounting without screws or extra hardware, making replacement projects more straightforward for both restorations and routine maintenance.
• Durable in the automotive environment — built to withstand the heat, humidity, and exposure typical of engine bays, helping you maintain a reliable seal over time.

Ideal use cases

• Restoration projects where the original radiator support/shroud seal has deteriorated or fallen out of place.
• Maintenance inspections where you’re r-sealing the radiator area to improve cooling efficiency and reduce air leaks.
• Repairs following impact or wear that misaligns the shroud, ensuring a precise, secure fit back to factory specs.
• OEM replacement in a performanc-upgraded engine bay where dependable airflow management is part of the plan.

What you gain with this fastener

• Consistent cooling performance by maintaining the intended airflow path, which can translate to steadier engine temps and better overall cooling efficiency.
• Fewer leaks and debris intrusions thanks to a reliable seal at the critical radiator/shroud junction.
• Longevity and peace of mind from a component engineered to hold its position through years of heat cycles and road conditions.

Installation tips for best results

• Inspect the mounting holes on the radiator support and shroud for any wear or deformation before installation.
• Align the fastener with the corresponding holes, ensuring the seal sits evenly along the shroud edge.
• Insert firmly with steady pressure until the fastener seats fully and the seal makes contact with the shroud surface.
• After installation, gently test the shroud’s stability and check for any gaps around the seal; r-seat if necessary to achieve a flush fit.

Designed specifically for the C3 Chevrolet Corvette platform from 1969 through 1978, this Pus-In Type Radiator Support/Shroud Seal Fastener delivers a focused, practical solution for restoring coolin-system integrity. If you’re rebuilding or refreshing your Corvette’s engine bay, this fastener helps you maintain authentic alignment and reliable performance without the fuss of loose, misaligned components.
