WARNING: This page is about a different car, the 2020 Jeep Renegade. However, it is still accessible from the selected car via links, so may be relevant.
The engine block has three 20 mm tapered plugs sealing the oil galleries (1) and one 14 mm plug sealing the water jacket (2). These threaded plugs do not have a torque specification but instead are installed to a specific depth. Do not attempt to further tighten these plugs, damage to the engine block could result. Whenever these plugs are removed they must be replaced. Service plugs have a lock patch and do not require the application of additional sealant.
