Jet, Piston Oil Cooler: Description: Description
WARNING: This page is about a different car, the 2013 Dodge Avenger and 2013 Chrysler 200. However, it is still accessible from the selected car via links, so may be relevant.
The 3.6 liter engine has three engine blocked-mounted oil jets (1) installed to cool the underside of each piston. The oil jets are fed by the main oil gallery, and spray upward on the bottom of the pistons and cylinder walls. Each set of jets has a check valve which closes below 2.5 bar (35 psi) to maintain ample oil pressure at idle. All three sets of oil jets are identical and seal to the engine block using an o-ring and fastener.
