Replacing or servicing the oil cooler on your Duramax and want to make sure the job stays leak-free once everything is back together? The MAHLE Engine Oil Cooler Gasket Set is designed to properly reseal the oil cooler assembly and restore dependable engine sealing during maintenance or repairs. The oil cooler plays a critical role in regulating engine oil temperature, and when the sealing gaskets wear out or are reused during service, they can lead to oil leaks, pressure loss, and potential engine damage. This OE-quality gasket set provides the correct sealing components needed to maintain proper oil flow and cooling performance, helping protect your engine under demanding conditions such as towing, heavy workloads, or daily driving. Whether you’re replacing the oil cooler or performing preventative maintenance, the GS34005 ensures the oil system remains properly sealed and operating as intended.
The MAHLE GS34005 is manufactured to meet strict OEM sealing standards, ensuring the same fit, function, and reliability as the original factory components. Each gasket is constructed from high-quality sealing materials engineered to withstand extreme engine heat, constant oil exposure, and long-term vibration without deteriorating or losing sealing integrity. Precision-formed for a direct fit to the oil cooler assembly, these gaskets maintain proper sealing pressure between the cooler and engine components to prevent leaks and maintain consistent oil circulation.
