Save Expensive Thermostats And Oil Lines
Stripped threads are a common problem when removing oil lines from the external thermostat.
The aluminum thermostat threads become fused to the steel tube nut that secures the oil lines. If you get enough leverage to force the nut free, it takes the aluminum threads along with it – destroying the expensive thermostat and the oil line.
Elephant Racing has the solution; we manufacture a 30mm tube nut replacement kit that let's you save thermostats and oil lines.
If your oil lines won't come free from the thermostat, use a cut-off wheel to slit the side of the tube nut. You can then break the nut free using a cold chisel. This technique sacrifices the tube nut to save the expensive thermostat.
You then use our kit to replace the tube nut that was cut off. Both the oil line and the thermostat are saved.
The kit provides a 2-piece tube nut. The threaded nut fits over the end of the tube and is slipped on first. A spring lock ring is then slipped on. The spring lock ring cinches down on the tube, preventing the nut from coming off

Engine Cooling Oil System & Pipes – Precision Cooling and Lubrication for Porsche Performance
The engine cooling oil system and pipes play a crucial role in your Porsche’s performance and reliability. These components deliver and regulate oil flow between the engine, oil cooler, and filter, maintaining stable oil temperature and pressure. By keeping the oil cool and circulating efficiently, they help prevent overheating, reduce friction, and ensure smooth engine operation — even under extreme driving conditions.
At Design911, we offer a complete range of genuine and manufacturer-quality engine cooling oil system parts and pipes for Porsche models including 911, Boxster, Cayman, Cayenne, Macan, and Panamera. Each component is engineered for precision fitment, high heat resistance, and long-lasting durability, ensuring your Porsche performs exactly as its engineers intended.
What Do Engine Cooling Oil System & Pipes Do?
The oil cooling system and its connecting pipes work
together to control temperature and maintain lubrication efficiency throughout
the engine. Their main functions include:
- Transporting
oil between the engine, oil cooler, and filter housing.
- Dissipating
excess heat from the oil to prevent breakdown under pressure.
- Maintaining
stable oil pressure for consistent lubrication.
- Supporting overall engine temperature regulation alongside the coolant system.
These parts ensure your Porsche’s engine oil stays at the ideal temperature and viscosity, protecting vital internal components from wear and damage.
Why Do Oil System Pipes and Components Fail?
Even with regular maintenance, oil cooling system components
can wear out due to heat, pressure, and age. Common causes of failure include:
- Corrosion
or cracking of metal oil pipes from long-term exposure to heat and
oil.
- Rubber
hose degradation from high temperatures or oil contamination.
- Leaks
at connectors or fittings caused by vibration or poor sealing.
- Blocked
or restricted flow from sludge or carbon build-up.
- Mechanical damage from debris or impact under the vehicle.
Signs of failure can include visible oil leaks, oil pressure warnings, overheating, or the smell of burning oil.
Why Replace Faulty Oil System Parts and Pipes?
A failing oil pipe or cooler line can cause oil loss, overheating, and even catastrophic engine failure if left unchecked. Replacing worn or damaged components ensures your Porsche’s oil circulation and cooling remain efficient and leak-free.
Benefits of replacement include:
- Restored oil flow and cooling performance.
- Prevention of leaks, overheating, and engine damage.
- Improved reliability and efficiency under all conditions.
- Manufacturer-quality materials for long-term durability.
All parts in this range are built from high-grade metals, reinforced hoses, and corrosion-resistant fittings, designed to meet or exceed factory standards for performance and longevity.
