Chevrolet Trailblazer EXT Parts

The TrailBlazer EXT from Chevrolet entered the market in 2002 featuring an extended wheelbase which provided better passenger and cargo volume along with optional third-row seating. A standard power system for the Chevrolet Trailblazer EXT uses a 4.2L inline-six engine to produce 291 horsepower and works with a four-speed automatic transmission to enable smooth gear changes and quick acceleration. Performance gets an improvement from the optional 5.3L V8 engine that provides 300 horsepower and 330 lb-ft torque with displacement-on-demands technology enabling cylinder deactivation during light driving thus saving fuel by 5 percent. The GMT370 internal chassis of the Chevrolet Trailblazer EXT allows three-row seating to fit seven passengers and creates space for 23.4 cubic feet of cargo despite its sufficient interior occupant capacity. The vehicle extends 207.8 inches in length and the 129 inches wheelbase assists driving stability effectively. The vehicle received suspension adjustments for comfort purposes which delivered smooth rides while reducing street noises for improved driving comfort. Uses of genuine Chevrolet components are essential for both performance quality and reliable operations of the TrailBlazer EXT. Using manufacturing-original components enables the retention of original factory specifications which results in prolonged the Chevrolet Trailblazer EXT maintenance.

Chevrolet Trailblazer EXT groups three concerns by fuel measurement, transmission drive, and front corner support. The Trailblazer EXT shows a propensity to show erratic gauge and low fuel warning in the fuel system. The wear of sulfur deteriorates the fuel level sender, leading to dropouts. Replace the fuel level sender and inspect the pump module wiring. Check cluster input and clean grounds on the Trailblazer EXT. In the drivetrain, the 4L60E in the Trailblazer EXT can slip in third and fourth. The 3-4 clutches overheat, and the sunshell strips splines. Expect delayed or harsh shifts and possible loss of reverse. Rebuild with updated clutches and a stronger sunshell, add an auxiliary cooler, and reset adaptives. For the front suspension hubs, the Trailblazer EXT may hum and trigger the ABS light. Unitized bearings pit with age and potholes. Replace the hub assembly and torque the axle nut to specification. Test Trailblazer EXT road test and check normal ABS reading and quiet rotation.
