Mounted within the alternator and cooling fan drive system, the pulley transfers rotational force from the engine belt to drive the alternator and engine cooling fan. Correct pulley operation ensures efficient charging system performance while maintaining the airflow required to cool the engine. Precision manufacturing helps provide smooth operation, accurate belt alignment and reliable long-term performance.

What This Product Does:

Transfers engine drive power to the alternator and cooling fan assembly.
Maintains correct cooling fan operating speed.
Supports efficient engine cooling.
Enables proper alternator operation and battery charging.
Ensures accurate drive belt alignment.
Helps minimise belt wear and slippage.
Contributes to reliable engine and electrical system performance.

Symptoms Of Wear Or Failure:

Squealing or chirping noises from the engine bay.
Drive belt slippage.
Excessive belt wear.
Charging system performance issues.
Battery warning light illumination.
Reduced engine cooling efficiency.
Visible pulley wear, cracking or damage.
Pulley wobble or misalignment.
Vibration from the alternator or fan assembly.
Belt throwing or repeated belt failures.

Why Replacement Matters:

Alternator fan pulleys are subjected to constant rotational loads, engine vibration, belt tension and temperature fluctuations. Over time, pulley surfaces can wear, become damaged or develop alignment issues that affect belt operation and drive system efficiency.
A worn pulley can lead to belt slippage, reduced alternator output and inadequate cooling fan performance. If left unresolved, this may result in battery charging problems, overheating risks, accelerated belt wear and potential damage to related drive system components. In severe cases, pulley failure can cause complete loss of alternator and cooling fan operation.
Replacing a worn alternator fan pulley restores proper belt alignment, reliable power transmission and efficient cooling system performance. An OE Match replacement provides factory-style fitment, precise engineering and dependable durability, helping maintain the performance and reliability of your Porsche engine and charging system.

Manufactured to OE specifications for fit, profile and durability, this comprehensive 8-piece engine tin baffle kit directs cooling air precisely around the engine and cylinders, helping maintain correct operating temperatures while protecting vital engine components.

Fits:

Porsche 911 1978-1983 3.0L / SC
Porsche 911 1984-1986 3.2L
Porsche 911 1987-1989 3.2L G50
Porsche 911 1975-1977 3.0L Turbo (930)
Porsche 911 1978-1989 3.3L Turbo (930)

Diagram Ref No 1

Manufactured from high-quality pressed steel with a durable corrosion-resistant finish, each baffle panel is precision-formed to replicate the original factory pressings for accurate fitment and straightforward installation. Designed for direct OE-style replacement, the kit restores the integrity of the engine cooling tinwork, making it ideal for engine rebuilds, restorations or replacing damaged, corroded or missing original baffles.

What This Product Does:

Directs cooling air through the engine as designed.
Helps maintain correct engine operating temperatures.
Prevents cooling air from escaping around the engine.
Improves cooling efficiency for cylinders and cylinder heads.
Protects the engine from road debris entering the cooling system.
Restores the original engine tin arrangement.
Provides factory-style fitment and appearance.
Forms an essential part of the air-cooled engine cooling system.

Symptoms Of Wear Or Failure:

Missing or damaged cooling tin panels.
Corroded or rusted engine tinwork.
Poor engine cooling performance.
Increased engine operating temperatures.
Warped or bent baffle panels.
Loose or rattling engine tin.
Gaps around the engine allowing cooling air loss.
Increased risk of overheating during warm weather or heavy use.
Poor-quality previous repairs or missing components.
Reduced originality during engine restoration.

Why Replacement Matters:

The engine tin baffles play a critical role in the cooling system of an air-cooled Porsche engine by directing airflow exactly where it is needed. Over time, corrosion, accident damage, improper engine servicing or missing components can disrupt this carefully engineered airflow, reducing cooling efficiency.
Damaged or incomplete engine tin can allow cooling air to escape before it reaches the cylinders and cylinder heads, increasing engine operating temperatures and accelerating wear. Prolonged overheating can reduce engine performance and contribute to costly internal engine damage.
Replacing worn or missing engine tin with the OE Match 8-Part Engine Tin Baffle Kit restores the original cooling airflow, improves engine temperature control and preserves the reliability of your air-cooled Porsche engine. Manufactured to OE standards from high-quality pressed steel, this kit provides factory-style fitment, long-lasting durability and is the ideal solution for Porsche engine rebuilds, restorations and preventative maintenance.
