What This Product Does

This radiator forms part of the engine oil cooling circuit. Heat passes out through the cooler, helping control the temperature of the oil used to lubricate internal engine components. The cooler works alongside the oil lines, thermostat and associated cooling hardware.

Functions

• Transfers excess heat away from engine oil.
• Supports oil temperature management during operation.
• Helps maintain suitable conditions for engine lubrication.
  
  

Technical Details

• Component: engine oil cooler.
• Installation position: inside the front wing.
• Brand: OE Match.
• Part identified in both supplied assembly diagrams: 96420722004.
  
  

Symptoms of Fault

• Oil drips or dampness around the cooler and connecting lines.
• Oily deposits across the cooling fins.
• Oil temperature remaining unusually high during sustained use.
• Damaged or obstructed fins restricting airflow.
• Visible corrosion or impact damage to the cooler.
  
  

Why Replacement Matters

A leaking or damaged cooler can compromise oil temperature control and allow oil loss. Renewing a confirmed faulty unit addresses the damaged component, but adjoining pipes, unions, seals and mountings should also be inspected. Establish whether leakage originates from the cooler itself or a nearby connection before replacement.

FAQs

Does high oil temperature prove the cooler has failed?
No. Oil level, thermostat operation and airflow can also affect temperature, so diagnosis should cover the wider system.

What should be inspected during replacement?
Check the connected oil lines, sealing points, mounting rubbers and surrounding airflow path for deterioration or damage.

How can a suspected leak be confirmed?
Inspect the cooler and its connections to locate the source; appropriate pressure testing can help confirm leakage.

What This Product Does

This pipe provides the supply connection within the external oil-cooling circuit. It carries oil between the thermostat assembly and front cooler; temperature-dependent flow control remains the thermostat's job, rather than a function of the pipe itself.

Functions

• Connects the thermostat assembly and front oil cooler.
• Provides the specified supply route along the vehicle.
• Contains circulating oil within the connected pipework.
  
  

Technical Details

• Brand: OE Match.
• Part number: 96420713304.
• External oil-cooler pipework
  
  

Symptoms of Fault

• Fresh oil beneath the vehicle or on its undertray.
• Wet patches along the line or around its connections.
• Corrosion, rubbing damage or visible cracking.
• An oil smell following a journey.
• Recurring oil loss requiring investigation.
  
  

These signs can have other causes. Identify the active leak before deciding which component needs replacement.

Why Replacement Matters

Renewing a damaged or leaking supply line addresses oil loss at the affected pipe. Heat cycles, vibration and ageing connections can contribute to deterioration, so inspect adjoining fittings, supports and seals during the repair. OE Match's Porsche-focused replacement programme uses application and original-reference checks when identifying suitable components.

FAQs

Is this the thermostat?
No. It is the connecting oil supply pipe, not the temperature-control assembly.

Can a connection cause the leak?
Yes. Inspect the unions and sealing points as well as the pipe body before replacing parts.

Should nearby mounting parts be checked?
Inspect clamps and supports for deterioration or looseness, and renew damaged hardware as appropriate.

Does this replace both long oil lines?
This description identifies the supply pipe only; do not assume the separate return line is included.

What should be checked after fitting?
Inspect the repaired connections for fresh seepage after the system has been through a heating and cooling cycle.
