S Hose Oil Cooler to Tank. Porsche 911 1974-89  ❭  91110723300

S Hose Oil Cooler To Tank.
The OE Match S Hose Oil Cooler to Tank is a high-quality replacement hose designed to connect the engine oil cooler system to the oil tank in classic Porsche applications. Commonly referred to as the "S Hose" due to its distinctive shape, this component plays a critical role in the dry sump lubrication system by allowing oil to flow efficiently between the oil tank and engine cooling circuit.

Fits:

• Porsche 911 1978-1983 3.0L / SC
• Porsche 911 1984-1986 3.2L
• Porsche 911 1987-1989 3.2L G50

Manufactured from durable, oil-resistant rubber and engineered to OE specifications, this replacement hose provides reliable sealing, correct fitment and long-lasting performance. It is an essential component for maintaining proper oil circulation and protecting the engine from lubrication-related issues.

What This Product Does:

• Connects the oil tank to the engine oil cooler system.
• Allows the transfer of engine oil throughout the dry sump lubrication system.
• Maintains proper oil circulation and cooling efficiency.
• Helps regulate engine operating temperatures.
• Ensures a consistent supply of oil to critical engine components.
• Supports overall engine lubrication and longevity.

Symptoms Of Wear Or Failure:

• Oil leaks beneath the vehicle or around hose connections.
• Cracked, split or perished rubber.
• Soft, swollen or deteriorated hose material.
• Oil seepage around the hose body.
• Low engine oil levels due to leakage.
• Burning oil smells from oil contacting hot engine components.
• Reduced oil system efficiency.
• Visible ageing, hardening or deformation of the hose.

Why Replacement Matters:

• The S Hose is constantly exposed to hot engine oil, pressure fluctuations, engine vibration and age-related deterioration. Over time, the rubber can harden, crack or weaken, increasing the risk of sudden oil loss. Because this hose carries a significant volume of engine oil, failure can result in rapid oil leakage that may lead to severe engine damage if not addressed immediately.
• Replacing a worn or ageing S Hose helps maintain proper oil circulation, prevents potentially catastrophic oil leaks and protects vital engine components from lubrication failure. An OE Match replacement restores the integrity of the oil system and helps ensure reliable performance from your Porsche's dry sump engine.
