Detailed Product Information

This Dorman vapor canister, part number 911-149, is engineered for direct replacement on vehicles that use a factory-style evap canister layout. It uses a plastic housing and carbon filter media to help manage fuel vapor storage within the evaporative emissions system. For drivers searching for a vapor canister for 2004-2016 Chevrolet Tahoe, 2004-2016 GMC Yukon, or 2004-2016 Cadillac Escalade applications, this part provides an OE-matched service solution. It also fits select 2004-2005 Buick Rendezvous, 2004-2005 Cadillac CTS, and 2004-2005 Cadillac SRX models.

This part number 911-149 cross-references Standard Ignition CP434 and CP524 for the same application.

What This Part Helps Address

  • Evaporative emissions fault codes related to vapor storage
  • Fuel vapor leaks from a damaged or saturated canister
  • Check engine lights tied to EVAP system performance
  • Failed emissions inspection caused by evap system issues
  • Odor concerns from a compromised vapor canister housing

Installation Notes and Tips

Verify port count, port diameters, and overall length against the original canister before installation. This vapor canister uses 3 ports and no connectors or terminals, so transfer and reconnect all EVAP hoses exactly as removed. Confirm vehicle application carefully, including the 2008-2013 Cadillac Escalade models that exclude the Advanced Hybrid System. Professional installation is recommended when diagnosing EVAP leaks or replacing related hoses and seals.

Quality Assurance

Dorman manufactures this vapor canister to match the original equipment evap canister on select vehicle years, makes, and models, helping restore emissions control function with an OE-style replacement design.
