043-119-317B VW Cylinder Tin Deflector Plates - Dual Port 1500-1600cc w/ 8mm Head Studs

Cylinder Tin Deflector Plates (Cool-Tin) for 8mm Head Studs – 043-119-317B

The 043-119-317B cylinder tin deflector plates, often referred to as "cool-tin," are vital cooling components for the air-cooled Volkswagen engine. These plates sit directly underneath the cylinders, spanning the gap between the cylinder fins. Their primary function is to catch the high-velocity air pushed down by the cooling fan and redirect it across the lower cylinder barrels and toward the cylinder heads, preventing localized hot spots that can lead to dropped valve seats or warped heads.

These deflectors are designed for dual-port engines but are widely used as an upgrade on single-port builds to improve thermal management. Without these plates installed, cooling air escapes too quickly out the bottom of the engine without absorbing enough heat from the cylinders. Manufactured from durable stamped steel, these plates are sold as a pair (left and right) and are a "must-have" for any engine rebuild to ensure long-term reliability.

Product Highlights & Features

• Optimized Airflow: Specifically contoured to force air through the deepest part of the cylinder fins for maximum heat dissipation.

• Heavy-Duty Stamped Steel: Built to withstand constant heat cycles without warping or rattling loose.

• Dual Port Specification: Fits 1500 -1600cc dual-port cylinder heads (with 8mm Head Studs) perfectly, providing a tight seal against the pushrod tubes.

• Corrosion Resistant: Finished in a protective black coating to resist rust and maintain a clean appearance within the engine bay.

Technical Specifications

• Part Number: 043-119-317B

• Material: Stamped Steel

• Quantity: Sold as a pair (Left & Right)

• Application: Type 1 based upright engines (1500 -1600cc with 8mm Head Studs)

Installation & Maintenance Tips

• Installation Timing: These must be installed before the pushrod tubes and cylinder heads are fitted. They snap onto the 8mm cylinder head studs and are held in place by the tension of these tins on the head studs.

• Check the Fit: Ensure the "ears" of the plates are not bent. If they are loose or vibrating, they can eventually saw through your pushrod tubes, leading to significant oil leaks.

• Orientation: The curved portion of the deflector should face downward to scoop and roll the air out toward the heat exchangers or over the lower engine tins.

• Seal Integrity: If using high-performance large-bore cylinders, you may need to slightly trim the edges of the 043-119-317B for a perfect, rattle-free fit.
