Diesel emissions testing due soon? Here’s the short version: in Colorado, diesel trucks like Cummins, Duramax, and Powerstroke engines must pass a state-certified emissions test every two years to stay compliant. At Branch Automotive in Littleton, CO, we perform a fast, non-invasive three-part test — engine control check, equipment inspection, and DYNO smoke density test — plus a complimentary safety inspection to keep you road-ready. Our ASE-certified team ensures your truck meets state standards without unnecessary disassembly or hidden costs.
Now, let’s break down what diesel emissions testing is, how the process works, and why Branch Automotive is the go-to choice for drivers in Littleton and Highlands Ranch.
What Is Diesel Emissions Testing?
Diesel emissions testing is a crucial part of maintaining clean air standards and ensuring your vehicle runs efficiently. In Colorado, diesel vehicles are required to pass emissions tests regularly to comply with state regulations. These tests help detect whether a diesel vehicle is emitting pollutants that exceed acceptable limits.
The Three-Part Diesel Emissions Test Process
At Branch Automotive in Littleton, CO, we make the emissions testing process simple, fast, and non-invasive. Here’s how it works:
- Electronic Engine Control Check
The first step of the emissions test involves checking the function of your vehicle’s electronic engine controls. This includes verifying that the check engine light illuminates and then goes off (a bulb check). During the test, we ensure that the check engine light stays off, indicating that your vehicle’s systems are functioning correctly. - Equipment Inspection
Next, we perform a thorough inspection to confirm that all the necessary equipment required when your vehicle was originally manufactured is still in place. This ensures that your vehicle meets the emissions standards set by the state of Colorado. - Dyno Test
The final part of the test is the DYNO test, where your vehicle is processed through a state-prescribed lug-down test. This test measures the density of the smoke coming from your vehicle’s tailpipe. To pass, the smoke density must remain under 20%. This is crucial for ensuring that your diesel vehicle is not contributing excessive emissions to the environment.
At Branch Automotive, we also perform a quick visual check to ensure there are no active fuel leaks. We check the engine oil and coolant levels before the test to ensure your vehicle is safe to undergo the emissions testing process.
Additional Value: Courtesy Safety Inspection
We believe in offering more than just a basic emissions test. As part of our service, we provide a complimentary courtesy safety inspection. This inspection visually checks common service items such as brakes, tires, the drive belt, and windshield condition. This extra step ensures that your vehicle is safe to drive and ready for the road.
