- Brand: OE Match.
- Specified application: Porsche 356B / 356C 2.0L Carrera, 1962–63.
- Supplied engine identifiers: 5871 / 5872; diagram notation: 587/1/2.
- Left-hand reference: 58710704100, diagram item 21.
- Right-hand reference: 58710704200, diagram item 22.
Symptoms of Fault
Oil leakage near the cooler or its connections, unusually high oil temperatures, or visible deterioration warrant inspection. These signs do not establish that the cooler itself has failed: adjoining pipes, unions and seals should also be checked before selecting replacement parts.
Why Replacement Matters
A leaking or restricted cooler can compromise oil retention or heat transfer. Replacing a confirmed faulty unit addresses that defect during maintenance or engine rebuilding. Inspect the connected pipework and sealing surfaces at the same time, rather than assuming that every nearby leak originates in the cooler.
FAQs
- Which reference identifies each side?
The supplied diagram assigns 58710704100 to LEFT and 58710704200 to RIGHT. Confirm the required side and reference before ordering. - Does the general 356B or 356C model listing confirm compatibility?
No. matches the more specific 2.0L Carrera application, engine identifier and production year as well. - Should related components be inspected?
Yes. Check the adjoining oil pipes, connections and seals for leakage or deterioration when assessing the cooler.

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.
