📖Chevrolet Colorado II Crew Cab Long Box: the heavy-duty commercial configuration

Chevrolet Colorado II Crew Cab Long Box (2015-2020)

Returning to the market with international GM underpinnings, the second-generation Colorado combined generous cabin accommodations with true commercial utility. In Crew Cab Long Box guise, it serves tradespeople and transport operators who demand four full-size passenger doors alongside an extended load bed. Dedicated Chevrolet Colorado maintenance is indispensable to ensure the hardworking powertrain and chassis components withstand sustained heavy towing.

Depending on the market, powertrain options focus on the 2.5 four-cylinder, the torque-rich 2.8-litre Duramax turbodiesel (LWN), and the petrol 3.6-litre V6 (LGZ). The Duramax diesel provides exceptional pulling stamina but requires rigorous adherence to diesel particulate filter (DPF) regenerations, AdBlue system dosing, and regular fuel filter renewals. High-spec petrol V6 variants mated to the 8-speed automatic gearbox demand vigilant monitoring for torque converter shudder and degraded transmission fluid.

Owner notes

The reassuring points, known weak spots and deadlines you should not let slip.

Reassuring points

Reliability
  • The Crew Cab Long Box layout successfully combines genuine five-seat cabin space with maximum cargo bed volume and heavy towing capacity.
  • The 2.8 Duramax turbodiesel provides outstanding low-end torque and impressive fuel economy under demanding towing duties.
  • When maintained with a straight load bed, healthy rear leaf springs, and fresh transmission fluid, it proves remarkably versatile.

Chronic weak spots

Keep an eye on
  • 2.8 Duramax diesel LWN: inspect EGR valve cleanliness, DPF soot loading, and the AdBlue tank heater for electronic fault codes.
  • 3.6 V6 LGZ: test the eight-speed automatic transmission at steady cruising speeds for torque converter shudder, hesitation, or rough shifting.
  • 2.5 petrol LCV: check high-pressure fuel pump operation, ignition coils, and inlet valve carbon build-up on direct-injected engines.
  • Four-wheel-drive system: inspect propshaft universal joints, front axle seals, and electronic transfer case range engagement.
  • Long Box chassis: inspect rear leaf spring packs, bed mounting rubber cushions, and towbar electrical harness for impact damage or corrosion.

Critical deadlines

Do not miss
  • The 2.8 Duramax emissions system, EGR circuit, and DPF regenerations must be addressed immediately if short urban trips cause warning lights.
  • The eight-speed automatic transmission fluid must be flushed with the updated Mobil 1 LV ATF HP formula at the first sign of torque converter shudder.
  • Rear leaf spring hangers, suspension bushings, and the tow hitch assembly require immediate servicing whenever chronic overloading causes bed sag.
