Oil Coolers / Radiators / Heat Exchangers

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.

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)

• 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.

• 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)

• 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.
