📖Chevrolet Trailblazer II Facelift: heavy-duty diesel capability for challenging terrains

Chevrolet Trailblazer II (facelift 2016) (2016-2020)

The 2016 facelift brought a sharper corporate nose and upgraded interior tech, yet the Trailblazer retained its heavy-duty body-on-frame construction designed for arduous environments. It preserved genuine off-road credentials and strong towing capacities, competing in international markets against tough utilitarian rivals like the diesel Kia Sorento and Toyota Fortuner. It remains an uncompromising vehicle engineered for long distances, rough tracks, and heavy loads, where regular Chevrolet Trailblazer maintenance keeps the driveline operating reliably.

Under the bonnet, the 2.5-litre and particularly the 2.8-litre Duramax turbodiesel four-cylinder units dominate, generating immense low-down torque best managed through the six-speed automatic gearbox. Certain markets retained the 3.6-litre petrol V6. Choosing between them dictates your maintenance routine: the diesels require rigorous attention to fuel injection, EGR valves, and DPF regeneration, whereas the petrol V6 demands disciplined cooling system monitoring and regular oil changes.

Owner notes

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

Reassuring points

Reliability
  • Uncompromising body-on-frame architecture that shrugs off harsh terrain and heavy towing duties.
  • The 2.8-litre Duramax turbodiesel offers generous torque and outstanding endurance when maintained by the book.
  • Substantially upgraded cabin trim, improved sound insulation, and modern touchscreen infotainment.

Chronic weak spots

Keep an eye on
  • 2.8 Duramax diesel: inspect common-rail injectors, variable geometry turbocharger, EGR valve, and DPF soot loading.
  • 2.5 diesel: check clutch wear on manual versions and monitor cooling system operating temperatures under load.
  • 3.6 V6 LFX petrol: monitor water pump health, coolant hoses, and ignition coil packs on petrol models.
  • Automatic gearbox and transfer case: test torque converter engagement, low-range selection, and rear differential quietness.
  • Chassis and running gear: examine suspension bushes, damper oil leaks, and chassis corrosion following off-tarmac use.

Critical deadlines

Do not miss
  • On 2.5 and 2.8 diesels, renew fuel filters and perform engine oil changes every 10,000 km to safeguard the high-pressure injection pump.
  • Service the automatic gearbox, transfer box, and front/rear differential fluids every 50,000 km or 3 years.
  • On 3.6 V6 petrol models, flush the coolant and inspect radiator hoses every 80,000 km to prevent thermal fatigue.
  • Inspect underbody chassis rails, suspension ball joints, and driveshaft gaiters after every off-road season.
