Used Pontiac Parts

Platform sharing is what makes a Pontiac sourceable. The Torrent was identical to the Chevrolet Equinox and the G5 was Pontiac's version of the Chevrolet Cobalt — Cobalt, G5, Saturn Ion and Chevrolet HHR all sit on GM's Delta platform. The G6 shares GM's Epsilon platform with the Chevrolet Malibu and Saab 9-3, and the Solstice uses GM's Kappa platform, which also underpins the Saturn Sky. Ask for the GM equivalent as well as the Pontiac name and the search widens immediately.

Two Pontiacs sit outside the GM North America parts tree. The Vibe (2003-2010) is a Toyota underneath: it shares the GM S / Toyota MC platform with the Toyota Matrix, is Corolla-derived, was built by the NUMMI joint venture in Fremont, California, and second-generation cars use Toyota's 1.8 2ZR-FE and the 2.4 2AZ-FE also used in the Camry and 2005-2008 RAV4. The G8 (2008-2009) is a rebadged Holden Commodore built in Australia on GM's Zeta platform.

• The 3.8-litre 3800 V6 in the Grand Prix carries repeated recalls for oil reaching the exhaust manifold — rocker cover gasket seepage on 1997-2003 supercharged cars, oil deposited on the manifold under hard braking on 1997-2003 naturally aspirated cars, and a later re-recall of 1997-2004 cars already repaired. The stated consequence each time is an engine-compartment fire. Check the VIN for open recalls and treat a burning-oil smell as a professional job.
• The 3.6-litre High Feature V6 is the other big one. GM service bulletin 12-06-01-009D covers timing chain and guide replacement, with codes P0008, P0009 and P0016-P0019, on 2007-2010 G6, 2008-2009 G8 and 2008-2009 Torrent fitted with the 3.6 (RPO LY7) and built after 15 July 2006. If your 3.6 sets one of those codes, get the chain assessed before spending on a used engine.
• Two safety-critical recalls matter here: 2007 Pontiac G5 cars (with the Cobalt, later joined by 2006-2007 Solstice) for ignition switches that could leave the run position and disable the airbags, and 2005-2009 G6 cars for sudden loss of electric power steering assist. Ignition, airbag and steering work is professional-install — confirm recall status by VIN first.

Safety- and emissions-related parts should be diagnosed and installed by a licensed mechanic.

• 'V6' is not an order. The G6 launched with a 3.5-litre pushrod V6 and later cars use the 3.6 that GM identifies by RPO code LY7. Give us the VIN or RPO code, not the displacement.
• The Grand Prix GXP's 5.3-litre LS4 V8 is front-drive-specific, with a shortened crankshaft and other changes made to fit the transverse platform. A rear-drive LS V8 is not a substitute.
• Order a Vibe as a Toyota, not a Pontiac — it shares the Matrix platform, is Corolla-derived and uses Toyota engines, so the engine code beats the badge.
• The G5 was sold in the US only as a coupe; the four-door was a Canada and Mexico car (Pursuit, G4 in Mexico). Confirm body style before ordering panels or glass.

Pontiac cars open the VIN with 1G2 when US-built and 2G2 when Canada-built; in a GM car VIN position 4 is the platform, 5 the series, 8 the engine type and 10 the model year. GM identifies engines by RPO code rather than displacement — its 3.6 bulletin lists affected cars as RPO LY7 — and those codes print on the Service Parts Identification label, commonly in the glove box.
