Zhermik EVAP Charcoal Vapor Canister for Silverado & Sierra 2004–2016 — Direct-Fit OE Replacement

Zhermik Fuel Evap Charcoal Vapor Canister is a direct-fit replacement charcoal canister designed to capture and store fuel vapors for compatible Chevrolet Silverado and GMC Sierra models.

This replacement vapor canister is built to match original-equipment form, fit and function for a range of 2004–2016 Silverado and 2004–2011 Sierra trucks. It uses high-density activated charcoal to adsorb fuel vapors, restoring the vehicle's evaporative emission control performance without custom modification. The unit is compatible with several OEM numbers (911-095, 12569373, 15137021, CP455, CP545, VC4124), making it a straightforward swap for the listed model years and trims when an EVAP canister fault is present.

How does this canister fit my Silverado or Sierra?

This Zhermik canister is manufactured to meet OE mounting points and inlet/outlet locations for specified model years and trims, allowing a bolt-in replacement in most cases. Before purchase, verify your vehicle's part number or compare the physical canister and hose connections to ensure compatibility.

• Fits: 2004–2016 Silverado 1500 Classic and selected HD models listed in the product details.
• Also fits: 2004–2011 GMC Sierra 1500 and specified HD/3500 variants.
• Compatible OEM numbers: 911-095, 12569373, 15137021, CP455, CP545, VC4124.
• Check: confirm your year, cab/bed configuration, and original canister shape before ordering.

What materials and performance features does it offer?

The canister is filled with high-density activated charcoal formulated to adsorb hydrocarbons efficiently while resisting collapse from vibration and heat cycles. It is produced to OE-equivalent durability standards, delivering consistent adsorption capacity and connection integrity under normal operating conditions.

• Core material: high-density activated charcoal for effective vapor adsorption.
• Construction: OE-spec housing and inlet/outlet port placements for secure fitment.
• Durability: resilient to typical engine-bay temperatures and road vibration.
• Function: restores EVAP vapor capture and routing when replacing a failed canister.

How difficult is installation and what should I expect?

Installation is typically straightforward for a mechanically inclined person with basic hand tools because the canister bolts into the original location and uses the existing hoses and fittings. Expect to remove a few fasteners and disconnect vacuum and vent hoses; if hoses or connectors are cracked, replace them to ensure a leak-free system.

• Tools: basic socket set, pliers, and screwdrivers usually suffice.
• Time: most installations take 30–90 minutes depending on vehicle access and rust conditions.
• Tip: inspect vacuum lines and purge valve for wear while replacing the canister.
• Relearns: some vehicles may require an EVAP system readiness cycle before diagnostic codes clear.

Will this fix an EVAP system trouble code?

Replacing a faulty or saturated charcoal canister can resolve many EVAP-related trouble codes tied to vapor storage and purge flow, but diagnostics should confirm the canister is the root cause. Other components—hoses, purge valve, pressure sensors—can also trigger codes, so check the entire EVAP system when troubleshooting.

• Common codes: P0440, P0442, P0455 may be associated with canister failure or leaks.
• Diagnostic step: smoke-test the EVAP system and inspect hoses before swapping parts.
• Comprehensive repair: replace worn hoses, grommets, or valves if found defective.

Who is this for: This Zhermik vapor canister is intended for Chevrolet Silverado and GMC Sierra owners, repair shops, and DIY technicians who need a reliable, OE-compatible replacement for the listed 2004–2016 Silverado and 2004–2011 Sierra models. Choose this unit if your diagnostics point to a saturated or damaged charcoal canister and you want a direct-fit component that matches OEM numbers 911-095, 12569373, 15137021, CP455, CP545, and VC4124.
