The 2006 model year

Overview

The 2006 Silverado light-duty range received revised front styling and added a 5-foot-8-inch Extended Cab short box, distinct from the standard and long Extended Cab boxes and the Crew Cab short box. The selected offerings below follow the dated ordinary 1500 and separate SS order appendices. Other combinations and optional packages remain under research; this is not a complete annual roster.

Year over year

What changed

  • The new Extended Cab short box has distinct CC15553/CK15553 identities; it is not the Crew Cab CC15543/CK15543 short box.
  • The light-duty front appearance changed; separate Heavy Duty and diesel updates are not applied to these 1500 offerings.
  • The SS two-wheel-drive offering began during interim 2005; the 2006 SS appendix documents a separate dated selection.

Worth knowing

Notable

  • Ordinary ordering is dated July 29, 2005; SS ordering June 17, 2005; separate HD material July 1, 2005 is not merged.
  • L33 requires CK15753 and the Light Duty Power Package (PDU), excluding the Z83 Solid Smooth Ride suspension package. Delayed 2LS ordering, regional packages and optional engines retain their source restrictions.
  • The manual permits E85 only for VIN Z/L59; none of these documented standard offerings is L59. Other engines use unleaded gasoline with engine-specific octane requirements. VIN N/LQ9 specifies 91+ premium and also permits 87+ regular with possible reduced acceleration/light knock.
  • Selected ownership topics do not certify every fitted-equipment duty. Verify actual engine, transmission and hardware using the full own-year manual.

Maintenance & service parts

Keep your 2006 Silverado on the road

Start with the service interval, then match the engine or exact version you own. Order links appear only when a catalog-backed part number is available, and every listing still needs a fitment check.

  • Gasoline engine oil and filterView intervals, applicability and sources

    Gasoline engine oil and filter

    Exact reference available

    Follow the gasoline Oil Life System: change oil and filter as soon as possible within 600 miles of the message, and at least once a year even without a message; reset after every change. If accidentally reset, change within 3,000 miles since the previous change, not a routine 3,000-mile interval. Use Maintenance I when the message occurs within 10 months of purchase or within 10 months after Maintenance II. Use Maintenance II after prior Maintenance I; always use II at 10 months or more since service or if no message appears for one year. Diesel requires its separate supplement. Fuel permission and octane are separate: VIN Z/L59 alone permits E85; none of these documented standard offerings is L59. VIN N/LQ9 specifies 91+ premium and also permits 87+ regular with possible reduced acceleration/light knock. Verify actual VIN and engine before using an engine-specific reference.

    Lubricate specified chassis components at Maintenance I and II. Severe-commercial operating conditions require regular 3,000-mile lubrication; this is not a universal interval. Ball joints must be at least 10°F component temperature before lubrication, not an ambient-temperature shortcut. The period specification is NLGI No. 2 Category LB or GC-LB; no current product is assigned.

    Applies to: 2006 · Vortec 4300 V6 (LU3), Vortec 4800 V8 (LR4), Vortec 5300 V8 (LM7), Vortec 5300 V8 (L33), Vortec 6000 V8 (LQ9) · MG5 5-speed manual with overdrive, M30 4-speed automatic with overdrive, M32 4-speed heavy-duty automatic with overdrive · United States · Only the documented 2006 gasoline standard offerings. Actual fitted hardware must be verified; no diesel, HD, generic displacement or adjacent-year inheritance.

    Published interval: At Maintenance I and II; severe-commercial use separately requires regular 3,000-mile lubrication. Preserve the ball-joint component-temperature condition.
