There is a spring loaded tensioner near the top of the belt. Insert a wrench (whatever fits the job) and pull/push against it. Remove the belt.
The 2003 GMC Envoy inline 6 engine does not have a timing belt but a timing chain. No need to replace anything unless the chain breaks.

Differences between the SLE and SLT. Body-color moldings come with SLE and brushed nickel with SLT. Inside, the SLE gets cloth seats and splashes of that brushed nickel on the console and instrument panel, while the SLT gets leather and wood with nickel trim rings. The driver gets an eight-way power adjustable seat with SLE; both driver and passenger with SLT. Seat position memory (including the heated outside mirrors) is standard on the SLT and heated seats are optional; neither are available with SLE. SLT also adds headlamp washers, driver information center, TravelNote digital recorder, rain-sensing wipers, light-sensitive outside mirrors with turn signals, and more controls on the steering wheel. SLE and SLT come with the same radio/CD sound system, with the SLT including rear seat jacks and controls. Upgraded systems are optional for both models, but only the SLT can get the Bose premium system. http://www.automobile.com/2002-gmc-envoy.html
The EGR valve is located on the front part of the engine on a 2002 GMC Yukon XL SLT. It is in front of the area where you add oil to the car.
The GMT360 platform LL8 inline 6 cyl Vortec 4200 engine is unique to the platform. The PCM and other electronics will be a nightmare to change to make anything else work or make it work in anything else. www.trailvoy.com Envoy enthusiasts forum.
