ACDelco 15803358 - C6 Corvette Auxiliary Engine Oil Cooler

Originally used in the 2006-08 Z06 427 7.0L LS7 engines, this heat exchanger was also used in the 2010 and later Dry Sump Grand Sport LS3 applications. Later GM would switch to a different type cooler for LS7 that used the engine coolant from the radiator. For performance track applications this was not a desirable solution and many Corvette owners would convert back to this type of oil cooler to reduce radiator coolant temps. The 2008 and 2009 Grand Sports have a much smaller cooler and this can be used as a direct replacement upgrade.

This heat exchanger transfers heat to and from your vehicle’s engine oil to the ambient air. This helps keep the engine oil temperature within the designed operating range, which helps optimize engine efficiency and longevity. These original equipment engine oil coolers have been manufactured to fit your GM vehicle, providing proven performance, durability, and the service life you expect from General Motors. Easily adaptable to all 2006-13 LS3 and LS7 applications for improved cooling.
