Crown Automotive 674234 Windshield Cowl Seal Weatherstrip

The Crown Automotive 674234 Windshield Cowl Seal is an OEM-quality replacement weatherstrip designed to restore a watertight barrier between the windshield frame and the cowl panel on classic Jeep CJ-3 and Willys M38 vehicles. A deteriorated or missing cowl seal allows water to infiltrate the cowl area, leading to rust, interior water damage, and compromised structural integrity — making timely replacement critical for restoration and maintenance builds alike.

This seal installs directly in place of the factory original, providing a precise fit without modification. It is an ideal time to replace this seal whenever the windshield frame has been lowered or serviced, as the area is already exposed and accessible.

Key Features:

• Direct OEM replacement cowl weatherstrip — no trimming or modification required
• Seals between the windshield frame and cowl panel to prevent water intrusion
• Manufactured to meet original equipment specifications for proper fit and function
• Made from premium rubber material engineered for long-lasting durability
• Backed by Crown Automotive's 12-month / 12,000-mile warranty

Crown Automotive has been a trusted name in Jeep replacement parts since 1963, offering one of the largest catalogs of OEM-spec components for Jeep vehicles produced since 1941. The 674234 cowl weatherstrip is a straightforward, high-value repair that helps preserve the integrity of classic Jeep CJ and Willys platforms.
