Why Chassis Codes Matter
Chassis codes provide the most accurate method of identifying your sixth generation Celica's exact specifications. While model designations like "GT" and "ST" can be ambiguous across different markets, chassis codes are universal identifiers that precisely define engine, drivetrain, and regional specifications.
Example: A USDM Celica GT uses the 135 HP 5S-FE engine, while a European Celica GT features the 180 HP 3S-GE engine. Ordering parts based on model name alone could result in receiving incompatible components. Chassis codes eliminate this confusion entirely.
🔍 Locating Your Chassis Code
The chassis code is permanently stamped into the firewall (rear wall of the engine bay) on all sixth generation Celicas. This 4-6 character alphanumeric code serves as your vehicle's definitive identification.
Location Instructions:
- Open the hood and secure it with the hood prop
- Look toward the cabin at the firewall (vertical panel behind the engine)
- Locate the stamped code - typically on the driver's side of the firewall
- Clean if necessary - dirt and grease may obscure the stamping
Examples: AT200, ST202, ST204, ST205, ST204C
🔧 Code Structure Analysis
Sixth generation Celica chassis codes follow a systematic format where each character position conveys specific technical information about the vehicle's configuration.
1st Character - Engine Family
2nd Character - Drivetrain
All 6th generation Celicas use "T"
3rd-4th Characters - Generation
Universal identifier for all 6th gen models
5th Character - Engine & Configuration
AWS = All-Wheel Steering (4-wheel steering system)
6th Character - Body Style
Optional character for convertible models only
