How to Identify Your Engine
To confirm the exact engine in a 1996 Blazer, use these quick checks:
- Open the hood and read the engine displacement stamped on the block or valve cover area (look for 4.3L or 5.7L).
- Check the under-hood emission/engine code label for the engine family and displacement information.
- Reference the Vehicle Identification Number (VIN) plate and the build sheet or option code to cross-check the original engine with the vehicle’s trim level.
Note: If the engine was swapped or replaced by a previous owner, labels or stamps may not match the vehicle’s original configuration. When in doubt, a professional inspection can confirm the engine type.
Summary
The 1996 Chevy Blazer offered two engine choices: a 4.3-liter V6 (the common base option) and a 5.7-liter V8 (an optional upgrade). Each engine delivered distinct performance characteristics and maintenance considerations, with the 4.3L favored for routine use and the 5.7L favored for higher-end towing and power needs. Verifying the exact engine is straightforward by inspecting the engine block markings, under-hood labels, and the vehicle’s documented trim codes.
