Built for strength and precision, this tool securely locks the crankshaft pulley in place, allowing safe and controlled removal or installation of the crank bolt during service, repairs or timing work.

Modern Porsche engines rely on extremely tight crank bolt torque values and a precision-balanced pulley. Without the correct dedicated holding tool, the pulley can slip, the crankshaft can rotate unexpectedly, or the high-torque fastener can cause damage to surrounding components. This tool eliminates those risks, ensuring a stable, damage-free and professional-grade service procedure.

What This Crankshaft Pulley Holding & Removal Tool Does

This specialised tool enables technicians to:

Firmly lock the crankshaft pulley to prevent rotational movement
Safely remove high-torque crankshaft bolts without slippage
Accurately install or torque crank bolts during reassembly
Support timing chain service, front crank seal replacement and engine-out work
Protect the pulley hub, keyway and crankshaft snout
Ensure correct alignment and prevent timing deviation

Essential for workshops dealing with EA825 and EA839 Porsche engines.

Compatible Porsche Models

Porsche Macan (95B.2)
– EA839 V6 engines (2.9 & 3.0 turbo)

Porsche Panamera (971)
– EA825 V8 engines
– EA839 V6/V8 engines

Porsche Cayenne (9YA)
– EA825 V8 Twin Turbo
– EA839 V6 Turbo & Hybrid variants

Suitable for all Porsche models using these VAG high-performance engine platforms.

Why Crankshaft Pulleys and Bolts Fail

Crankshaft pulleys on high-output EA825 and EA839 engines can experience issues such as:

Pulley bolt seizure due to extreme torque and heat cycles
Rubber damper wear, affecting pulley stability
Pulley slippage from improper past servicing
Heat-induced expansion locking the pulley onto the crank
Corrosion on the mating surfaces
Over-tightening or incorrect tool use, causing distortion

A professional holding tool eliminates these risks during service.

Why You Should Use or Replace With a Precision Pulley Holding Tool

A dedicated crankshaft pulley tool ensures:

Damage-free removal and installation
Perfect crankshaft stability during timing or seal work
Accurate torque application for proper engine function
Protection of expensive engine components
Reduced risk of timing misalignment
Professional reliability for repeated workshop use

Replacing cheap or worn tools avoids slipping, bent arms and incomplete clamping force—common causes of pulley damage.

Engine oil cooler. Porsche 95B.2 Macan 3.0L / 971.1 Panamera 3.0L / 9YA Cayenne 3.0L

9A711701530

Product Information

Engine oil cooler.
This genuine Porsche Engine Oil Cooler is a key thermal management component for the 3.0 L V6 engines in the Porsche 95B.2 Macan, 971 Panamera, and 9YA Cayenne platforms. It efficiently removes excess heat from the engine oil, improving performance stability, reducing wear, and helping ensure peak engine longevity. Its true Porsche OE construction maintains factory-intended cooling characteristics and reliability.

Fits:
Porsche 95B.2 Macan S 3.0L 2019>> (engine code: DLZ,DLZB)
Porsche 971.1 Panamera 3.0L V6 2017 - 2021 (engine code: CXTA,CXT)
Porsche 9YA.1 Cayenne 3.0L 2018 - 2023 (engine code: DCBE, DCB)
Porsche 9YA.2 Cayenne 3.0L 2023>> (PR:T9I)

Diagram ref no 19

The engine oil cooler helps regulate the temperature of the engine oil, which is critical for:
•  Protecting engine internals from heat damage
•  Maintaining stable oil viscosity
•  Reducing wear and friction losses
•  Supporting consistent performance under heavy driving, hot ambient temperatures, or towing

Oil that runs too hot loses lubricating properties, increasing friction and accelerating wear. By circulating hot engine oil through a dedicated heat exchanger where heat is transferred away into coolant or ambient air, the oil cooler keeps temperatures in an optimal range - supporting engine reliability, performance, and longevity.

Fitment / Position on Car
• Installed on: Front end of engine bay near coolant radiators, integrated with oil and coolant lines
• Position: Typically mounted ahead of or alongside the engine block, interfacing with dedicated oil lines and the coolant circuit
• Connection: Uses Porsche-specific fittings and seals for leak-free integration with OE lines

Engine oil not only lubricates but also helps carry heat away from internal surfaces. In high-performance turbocharged engines, oil temperatures can spike rapidly if not effectively controlled. A genuine Porsche OE oil cooler like 9A711701530 ensures heat is effectively removed from the oil, protecting internal components and maintaining optimal lubrication characteristics under a wide range of operating conditions.

Diagram ref no 19

Installed within the engine lubrication circuit, the oil cooler circulates hot engine oil through a series of finned cooling channels where heat is dissipated before the oil returns to the engine. By maintaining optimal oil temperatures, it reduces thermal stress, helps preserve oil viscosity, and supports consistent lubrication - critical for long-term engine reliability and performance.

MAHLE’s precision-engineered cooler is designed for use with 3.0 L engines in a range of Porsche models, providing reliable cooling capacity and direct fitment as a replacement for the OE unit.

Fitment / Position on Car
• Installed on: Front end of engine bay near coolant radiators, integrated with oil and coolant lines
• Position: Typically mounted ahead of or alongside the engine block, interfacing with dedicated oil lines and the coolant circuit
• Connection: Uses Porsche-specific fittings and seals for leak-free integration with OE lines

Engine oil not only lubricates but also helps carry heat away from internal surfaces. In high-performance turbocharged engines, oil temperatures can spike rapidly if not effectively controlled. A fresh oil cooler ensures heat is effectively removed from the oil, protecting internal components and maintaining optimal lubrication characteristics under a wide range of operating conditions.
