What This Product Does

The heat exchanger transfers heat away from the engine oil to help manage its temperature. Oil temperature control supports the lubrication system by limiting excessive heat within the circulating oil.

Functions

  • Transfers excess heat from engine oil.
  • Helps regulate oil operating temperature.
  • Supports lubrication through oil temperature management.

Technical Details

  • Brand: NRF.
  • Supplied reference: 95810727130.
  • Component identified in the assembly diagram: oil cooler.
  • Engine/model identifiers: CUDB, CUDC.
  • Assembly context: oil filter, console and oil cooler.

Symptoms of Fault

  • Oil seepage or dampness near the cooler and its seals.
  • Oil temperatures that remain unusually high.
  • Coolant loss without an obvious external source.
  • An oily layer or sludge in the coolant reservoir.
  • Milky contamination in the oil, where an internal fault permits fluid mixing.
  • Unstable engine temperatures.

These signs can have other causes. Inspect the cooler, seals and connected components before deciding which part requires replacement.

Why Replacement Matters

A leaking or internally restricted heat exchanger can compromise oil temperature control. Where internal damage allows oil and coolant to mix, the underlying fault needs repair before contaminated systems are cleaned. Inspect surrounding seals and connections during the work rather than assuming every leak originates in the cooler itself.

FAQs

Does oil in the coolant prove that the head gasket has failed?
No. A heat exchanger fault is another possible source, so diagnosis should establish where the contamination begins.

Will flushing resolve a defective cooler?
Flushing removes residue but does not repair a leak or damaged internal passage. Address the cause before cleaning the affected circuits.

Should nearby seals and hoses be inspected?
Yes. Check for seepage, deterioration and contamination-related damage, and renew affected components as required.

How is a suspected fault confirmed?
Visual examination, appropriate pressure testing and checks for fluid contamination help distinguish cooler faults from problems elsewhere in the engine or cooling system.

About Oil Coolers / Radiators / Heat Exchangers

Engine Oil Coolers, Radiators & Heat Exchangers – Precision Cooling for Porsche Performance

The engine oil cooler and heat exchanger system plays a critical role in managing temperature within your Porsche’s engine. By transferring excess heat away from the oil and other fluids, these components ensure stable operating temperatures, consistent lubrication, and maximum engine longevity — especially under demanding performance conditions.

At Design911, we offer a full range of engine oil coolers, radiators, and heat exchangers for Porsche models old and new. Built from high-efficiency aluminium or reinforced composite materials, these components are designed to deliver superior cooling performance, durability, and perfect fitment — ensuring your Porsche performs at its best, on road or track.

Whether replacing a worn-out unit or upgrading for improved thermal efficiency, our oil cooling components provide reliable temperature control and enhanced performance.

What Do Engine Oil Coolers, Radiators & Heat Exchangers Do?

These components regulate oil and engine temperatures to maintain optimal performance and prevent overheating.

Core Functions:

  • Dissipate excess heat from the engine oil, coolant, or transmission fluid.
  • Maintain consistent oil viscosity and prevent breakdown under load.
  • Protect internal engine components from heat-related wear and failure.
  • Improve overall performance efficiency during extended drives or track sessions.

Together, the oil cooler, radiator, and heat exchanger form an essential thermal management system, helping your Porsche run at peak performance while protecting vital components.

Why Do Oil Coolers & Heat Exchangers Fail?

Over time, exposure to heat cycles, vibration, and contaminants can lead to efficiency loss or complete failure.

Common Causes of Failure Include:

  • Corrosion or cracking from age or road debris impact.
  • Internal clogging caused by sludge or contaminated oil.
  • Leaking seals or fittings, reducing pressure and fluid efficiency.
  • Thermal fatigue, leading to reduced cooling capacity.
  • Poor maintenance or coolant neglect, accelerating deterioration.

Symptoms of failure can include high oil temperatures, oil leaks, coolant contamination, or reduced engine performance, all of which signal the need for inspection or replacement.

Why Replace Oil Cooling Components?

Replacing a worn or leaking oil cooler, radiator, or heat exchanger is essential to preserve lubrication quality and prevent costly overheating damage. Our precision-fit, high-durability components restore proper cooling balance and reliability under all conditions.

Key Benefits:

  • Restores efficient oil and fluid temperature regulation.
  • Prevents overheating and engine wear.
  • Improves reliability under heavy load or track use.
  • Constructed from corrosion-resistant, high-performance materials.
  • Direct-fit compatibility for classic and modern Porsche engines.
  • Ideal for rebuilds, maintenance, and performance upgrades.

Upgrading or replacing your cooling system components helps ensure your Porsche’s engine stays efficient, durable, and ready for spirited driving.

Highlights:

  • Comprehensive range of Porsche oil coolers, radiators, and heat exchangers.
  • Precision-engineered for consistent temperature control.
  • Constructed from lightweight, corrosion-resistant materials.
  • Designed for reliability in both road and motorsport conditions.
  • Improves lubrication and protects engine performance.
  • Perfect for maintenance, rebuilds, or performance enhancements.
