Here's why:
* Engine Variations: Chrysler PT Cruisers with 2.4L engines might have slightly different configurations depending on the model year and production run.
* No Universal Standard: There's no universal standard for cylinder numbering in the automotive industry. Each manufacturer might use a different system.
How to Find the Answer:
1. Consult Your Owner's Manual: The most reliable source for this information is your car's owner's manual.
2. Locate the Engine Tag: There should be a sticker or tag on the engine itself, often near the valve cover, which might include a diagram of the cylinder numbering.
3. Look Online: Try searching for your specific model year PT Cruiser online. You might find a service manual or forum posts that clarify cylinder numbering.
Important Note: It's crucial to have accurate cylinder information when diagnosing engine issues, performing maintenance, or replacing parts.
