Oil lines are often overlooked components, yet their failure can lead to significant damage. These lines connect the engine, oil cooler, or timing chain tensioner, functioning reliably for years without drawing attention.

However, if a crack or break develops, substantial amounts of oil may leak—potentially draining the entire oil tank—leaving critical components without proper lubrication. To prevent such failures, it is advisable to replace aging oil hoses or lines at the first signs of wear.

In the context of full restorations, replacing all oil lines or hoses is a common and prudent practice to ensure long-term reliability.

Radiator Oil Cooler Kit.

This Radiator Engine Oil Cooler Kit is a complete genuine spec solution designed to restore proper oil temperature control and leak-free operation in classic air-cooled Porsche 911 engines. The kit includes the engine oil cooler along with all required seals, fittings, and the connecting hose to ensure a correct, reliable installation.

Fits:

• Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
• 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)

Diagram Ref No 2, 3, 6, 16, 17, 22, 23

The oil cooler plays a critical role in regulating engine oil temperature by dissipating excess heat generated during normal driving and high-load conditions. Proper oil cooling helps maintain oil viscosity, protects internal engine components, and ensures long-term engine reliability. Over time, oil coolers can become restricted internally, while seals and hoses harden and begin to leak, compromising cooling efficiency and lubrication.
This kit replaces the oil cooler assembly along with the associated suction hose, O-rings, seals, and mounting components, eliminating common leak points and restoring factory-correct oil flow. All components are manufactured to OEM specifications, ensuring precise fitment, proper sealing, and dependable performance.
Ideal for engine rebuilds, restorations, or preventative maintenance, this oil cooler kit provides a complete, professional solution for maintaining correct oil temperature and protecting valuable classic Porsche engines.

What This Product Does:

• Regulates engine oil temperature: Oil absorbs heat from engine internals. Too hot, and its lubricating properties break down. The cooler releases excess heat into the surrounding air.
  
• Improves engine reliability: Cooler oil maintains viscosity and lubrication under high load, reducing wear.
  
• Protects critical components: Helps maintain optimal oil temperature, protecting bearings, cams, pistons, and other moving parts that depend on consistent lubrication.
  
• Includes all mounting & sealing hardware: Ensures a complete, correct OEM install — no missing seals or leaks.

Symptoms Of A Failing Oil Cooler System:

• High oil temperature under normal driving conditions
• Oil leaks around the cooler, seal rings, or hose connections
• Visible oil seepage near cooler fittings
• Reduced engine performance or overheating
• Frequent oil top-ups due to unseen leaks
• Sludge formation inside or around the cooler/hose (indicative of internal deposits)

Why Replacement Matters:

• Properly controlled oil temperature extends engine component life — especially under sustained load or high ambient temperatures.
• Cool oil holds its protective viscosity and prevents metal-to-metal contact that accelerates wear.
• Old seals and O-rings lose elasticity over time, leading to slow leaks.
• A full kit replaces all necessary sealing points.
• This kit uses genuine Porsche parts, ensuring correct fitment and compatibility with the factory oil cooling system on your 911.
• Correct oil temperature helps sustain peak engine performance, especially in spirited driving or classic car restoration scenarios.

Radiator oil cooler rubber buffer, SET OF 3
This replacement buffer is a high-quality replacement for the factory bonded-rubber mounts used to support the oil cooler assembly in air-cooled Porsche engines. It helps isolate vibration, maintain correct alignment, and protect the cooler and adjoining hardware.

Fits:
Porsche 911 1984 - 1989

Diagram Ref No 14.

This is a rubber buffer or mount (often bonded to metal inserts) used to cushion and secure the oil cooler assembly relative to the engine or chassis. It absorbs vibration, prevents metal-to-metal contact, and keeps the cooler in its correct position. It helps avoid stresses on oil cooler brackets, lines, and mating surfaces by providing a flexible mounting point.

Replaces: Porsche 930.207.239.00 / 930.207.239.01 / 930.207.239.02
Position: Between oil cooler and engine or chassis mount — isolates vibration and supports alignment
Function: Absorbs vibration and engine movement, prevents stress on oil cooler lines and brackets
Installation: Direct-fit OE replacement — install as a set for best results
Maintenance Tip: Replace when rubber hardens, cracks, or separates from metal housing

Over time, the rubber in the buffer mount degrades due to heat, oil exposure, ozone, vibration, and fatigue. It may harden, crack, shrink, or separate from its bonded metal insert. A failed mount lets the oil cooler shift or vibrate more than designed, putting strain on cooler hoses, brackets, and mounting flanges — potentially leading to leaks or damage. Excessive vibration may cause noise, misalignment, or premature fatigue of supporting parts. You should replace this buffer when you notice damage or deterioration, when removing or servicing the oil cooler, or as preventive maintenance on high-mileage engines.
