The engine bay of a 2016 Jeep Wrangler Unlimited JK Unlimited (JKU) can seem daunting at first glance, a complex maze of hoses, wires, and components. However, understanding its layout is crucial for maintenance, repairs, and even simple modifications. This guide provides a detailed overview, addressing common questions and helping you navigate this vital area of your Jeep.

What are the major components in the 2016 Jeep JKU engine bay?
The 2016 Jeep JKU engine bay houses a multitude of essential components. Key areas include:
-
Engine: This is the heart of the vehicle, responsible for generating power. The 2016 JKU models offered several engine options (3.6L Pentastar V6 being the most common). Locating the engine is straightforward; it’s the largest component in the bay.
-
Transmission: Connected to the engine, the transmission manages power transfer to the wheels. Its location varies slightly depending on the transmission type (automatic or manual).
-
Cooling System: This includes the radiator, coolant hoses, water pump, and thermostat. These work together to regulate engine temperature. They are typically located at the front of the engine bay, behind the grille.
-
Electrical System: This encompasses the battery, alternator, starter motor, and numerous wiring harnesses. The battery is usually located on the passenger side (right side in the US).
-
Air Intake System: This includes the air filter housing and intake manifold, responsible for supplying air to the engine. This is usually positioned near the front of the engine.
-
Exhaust System: This begins at the engine's exhaust manifolds and routes exhaust gases out of the vehicle.
-
Power Steering System: The power steering pump, reservoir, and hoses are generally located near the engine's front.
-
Brake System (Master Cylinder): Frequently found near the firewall, towards the passenger side, but its exact location might vary based on the model.

Unfortunately, a single, all-encompassing, free, and readily accessible online diagram for the entire engine bay of a 2016 JKU isn't publicly available. This is because diagrams are often specific to individual engine options, optional packages, and even minor production variations.

Online Automotive Parts Websites: Many websites specializing in Jeep parts offer diagrams integrated with their parts catalogs. Searching for specific components (e.g., "2016 Jeep JKU radiator hose diagram") might yield relevant visuals.
-
Independent Repair Manuals: Several publishers produce comprehensive repair manuals with detailed diagrams. These are typically paid resources.
