C5213-045

Overview:

The Cometic Gasket MLS (Multi-Layer Steel) Cylinder Head Gasket is engineered to deliver superior sealing performance for high-output 4.7L PowerTech engines found in select Jeep and Dodge vehicles from 1999 to 2007. Designed for durability and reliability, this gasket is ideal for enthusiasts and professional mechanics seeking a dependable replacement that withstands the rigors of daily driving and performance applications alike. Its advanced construction eliminates the need for additional sealants, ensuring a precise and lasting seal between the cylinder head and engine block.

Perfectly suited for aluminum-to-aluminum and aluminum-to-cast iron engine configurations, this gasket addresses the challenges posed by differing metal expansion rates, providing a resilient seal that resists blowouts and leaks under extreme conditions.

Key Features:

Cometic’s MLS Cylinder Head Gasket incorporates cutting-edge materials and design elements to maximize engine sealing integrity and longevity:

• Multiple embossed layers of stainless steel for enhanced strength and flexibility
• Outer layers coated with Viton rubber for superior heat resistance and chemical durability
• Compressed operating thickness of 0.045 inches for optimal sealing performance
• Embossed outer layers improve gasket sealing under high clamping loads
• Center shim layer of uncoated stainless steel tailored for precise thickness and durability
• Resistant to corrosion and capable of rebounding to maintain a tight seal over time
• Designed to withstand shearing forces between aluminum heads and cast iron blocks
• No sealants required, simplifying installation and reducing potential failure points

Construction & Design:

The Cometic MLS gasket features a robust multi-layer steel construction, combining the strength of stainless steel with the resilience of Viton rubber coatings. The outer layers are embossed stainless steel, coated on both sides with Viton—a high-performance fluorocarbon elastomer known for its exceptional heat resistance up to 250°C (482°F) and chemical stability. This coating ensures the gasket maintains a reliable seal even in harsh engine environments.

The uncoated stainless steel shim layer at the core provides structural integrity and allows for precise thickness customization to meet specific engine requirements. This layered design enables the gasket to absorb and compensate for thermal expansion differences between aluminum cylinder heads and cast iron blocks, preventing leaks and gasket failure.

Installation & Fitment:

This MLS cylinder head gasket is a direct replacement designed to fit a wide range of Chrysler 4.7L PowerTech engines installed in Jeep Grand Cherokee (1999–2007), Dodge Dakota (2000–2007), Dodge Durango (2000–2007), and Dodge Ram 1500 (2002–2007) models. Installation requires standard head gasket replacement procedures with no special modifications or sealants needed, making it suitable for professional mechanics and experienced DIY enthusiasts alike.

Ensure proper torque specifications and head surface conditions during installation to maximize gasket performance and longevity.
