Detailed Description

This vapor canister is made to match the original equipment evap canister used on select 1997-2002 Chevrolet Blazer, Chevrolet S10, GMC Jimmy, GMC Sonoma, and 1997-2000 Oldsmobile Bravada applications, along with select Cadillac DeVille and Cadillac Eldorado models. Dorman 911-271 helps restore the evaporative system’s ability to capture fuel vapors and route them through the emissions control system as the vehicle was originally engineered to do. This part cross-references Standard Ignition (e.g., CP445, CP535) for the same application.

What It Helps Address

• Evaporative emissions system fault codes
• Fuel vapor odor around the vehicle
• Damaged or cracked canister housing
• Charcoal media breakdown inside the canister
• Loss of proper vapor storage in the EVAP system
