Engine oil heat exchanger & gaskets kit. Porsche 958 Cayenne / 970 Panamera  ❭  94810728122

Engine oil heat exchanger & Gaskets.
OE Match engine oil heat exchanger (sometimes called an oil cooler or oil-to-coolant heat exchanger) - is a precision-engineered cooling component designed to help regulate engine oil temperature by transferring heat between the engine oil circuit and the engine coolant.

Fits:
Porsche 958 Cayenne V6 3.6L 2015 - 2018
Porsche 958 Cayenne S / GTS / TURBBO 4.8L 2011- 2018
Porsche 970 Panamera V6 3.6L 2010 - 2016
Porsche 970 Panamera S / GTS / TURBO 4.8L 2011 - 2016

The engine oil heat exchanger facilitates thermal management of the engine oil by using the engine’s coolant flow to remove excess heat from the oil. This helps:
•  Maintain stable oil temperatures during normal and strenuous engine operation
•  Reduce oil degradation caused by overheating
•  Support consistent oil viscosity for effective lubrication
•  Improve long-term engine component longevity.

By dissipating heat from the oil into the coolant, the heat exchanger helps prevent oil temperatures from rising excessively - which is particularly important in high-load, high-ambient-temperature, or spirited driving conditions.

Function:
•  Transfers heat from circulating engine oil to the coolant
•  Supports optimal oil temperature to preserve lubrication properties
•  Prevents oil overheating, which can accelerate wear
•  Works as an integrated part of the engine’s cooling and lubrication systems.

Without a functioning oil heat exchanger, engine oil can run hotter than ideal - increasing the risk of reduced oil life, compromised lubrication, and premature engine wear.

The engine oil heat exchanger plays a critical role in managing engine lubrication temperatures. Over time, the heat exchanger can become clogged, corroded, or develop internal leaks between oil and coolant circuits. A failing heat exchanger can lead to:
•  Elevated oil temperatures
•  Reduced oil life
•  Loss of coolant or oil cross-contamination
•  Engine lubrication breakdown
•  Overheating or degraded performance.

Replacing a worn or failed heat exchanger with a quality OE Match unit restores effective oil cooling, enhances engine reliability, and helps ensure long-term protection of pistons, bearings, and other vital components.

When to replace. Replace the engine oil heat exchanger when:
•  Oil temperature readings are unusually high
•  Coolant contamination in the oil (or vice-versa) is suspected
•  Visible leaks from the heat exchanger or its connections
•  You are performing a major engine service or overhaul
•  Signs of corrosion, blockage, or thermal inefficiency are present
