Greeley Automotive Machine can test your light-duty diesel vehicle for Colorado's diesel air program. We are limited to light-duty vehicles meaning 14,000 GVWR and lighter and under twelve feet tall.

Testing Times: Monday thru Friday 8:00 a.m. to 4:30 p.m. 

Weather Conditions: We are required to maintain a minimum of 42 degrees in the test cell. So tests can only be done if outside temperature is above 30 degrees. We also need dry tires to grip the dyno rollers, so we cannot do tests if it is raining, or if there is considerable snow on the roads.

Please call 970-352-4342 to schedule your appointment.
