The Derale 35611 is an LS oil cooler bypass adapter kit that adds oil cooler ports to a GM LS engine so an external engine oil cooler can be plumbed in. The adapter installs in the engine oil system, and the cooler lines connect to its IN and OUT ports. These ports must be connected to a cooler or looped together and should never be capped, since that would block oil flow. This is the standard, non-thermostatic version of the adapter; the thermostatic end cap is used only on the companion 35621 kit.
