Heat exchanger tester for Porsche 996 / 997

stomski

Some M96/M97 engines are experiencing oil-to-coolant intermixing. While there are potentially several sources of intermixing, faulty engine mounted oil-to-coolant heat exchangers are a major source. Now, with STOMSKI RACING's M96 Heat Exchanger Tester, you can confirm if your exchanger is faulty and needs replacing, or whether the source of the contamination is elsewhere. This high-quality tool is CNC machined from 6061 aluminum, anodized for years of service, and comes complete with all gauges, seals and hardware.

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.
