Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Engine Identification
Engine may be identified by Vehicle Identification Number (VIN), engine block code or partial VIN. VIN is stamped on a metal pad located near lower left corner of windshield. The eighth character of VIN identifies engine model ("T" indicates 3.1L PFI engine). The tenth character of VIN identifies model year ("N" indicates 1992 model year). Do not confuse VIN with the 9-character partial VIN shown in Fig. Fig 1. The engine block code (3 characters) is stamped on left side of cylinder block, at cylinder block-to-transaxle/transmission flange (LHO indicates 3.1L PFI engine).
| Application | Engine Code | VIN Code |
