• Improved Understanding: Gain a deeper understanding of how your engine operates.
• Enhanced Safety: Reduce the risk of damaging components or injuring yourself.

Chevrolet HHR Engine Options: Knowing Your Specific Configuration

The Chevrolet HHR was offered with several engine options throughout its production run (2005-2011). Knowing which engine your HHR is equipped with is the first step to accessing the correct engine diagram. These include:

• 2.2L Inline-4 (L61): A common and reliable engine found in many base models.
• 2.4L Inline-4 (LE5): An upgraded version of the 2.2L, offering slightly more power.
• 2.0L Turbocharged Inline-4 (LSJ): Featured in the HHR SS, this engine delivers significant performance.

Locating Your Engine Code:

The engine code is typically located on a sticker under the hood or in the owner’s manual. This code is essential when searching for specific engine diagrams.

Key Components and Their Locations: Navigating the Engine Compartment

While the exact layout may vary slightly depending on the engine, some key components are consistently positioned. Familiarizing yourself with these will greatly assist you in using your engine diagram.

• Engine Block: The central foundation of the engine, typically located at the bottom of the engine compartment.
• Cylinder Head(s): Located on top of the engine block, housing the valves and spark plugs.
• Intake Manifold: Supplies air and fuel to the engine, usually located on the front or top.
• Exhaust Manifold: Collects exhaust gases and directs them away from the engine, typically on the rear or side.
• Fuel Injectors: Deliver fuel to the cylinders, often located within the intake manifold.
• Spark Plugs: Ignite the air-fuel mixture within the cylinders, found within the cylinder head(s).
• Cooling System Components: Radiator, water pump, hoses, and coolant reservoir, typically located at the front of the engine.
• Air Intake System: Air filter, mass airflow sensor (MAF), and intake tubing, often located on the side or top of the engine.
• Sensors and Actuators: Numerous sensors (e.g., crankshaft position sensor, camshaft position sensor) and actuators (e.g., throttle body) are strategically placed throughout the engine.
