Additional Notes
- The Pontiac Aztek 3.4 V6 cooling system holds 9.1 liters, a figure that represents the total system fill capacity rather than a reservoir-only or partial service volume.
- The 150,000-mile change interval for the 3.4 V6 coolant is paired with a 60-month time limit, meaning whichever threshold arrives first would govern the service point under normal use conditions.
- A 12-month check interval is specified separately from the full change interval, indicating that coolant condition and level are to be inspected annually well before the 150,000-mile or 60-month replacement point is reached.
- The 150,000-mile coolant change interval reflects the extended-life characteristics associated with the DEX-COOL type coolant that General Motors specified for the 3.4 V6 during the 2001-2005 production span, as opposed to the shorter intervals typical of conventional green coolant formulations.
- The single capacity figure of 9.1 liters applies uniformly across the 2001-2005 model years for the 3.4 V6, with no variation recorded between those years in the specifications.
