2008 Kia Optima Service and Repair Manual

This factory service and repair manual is written for the 2008 Kia Optima specifically — matched to the year, the engine under the hood, and the trim on the badge — so every specification and sequence it quotes is the one Kia published for this sedan rather than a near figure inherited from an adjacent model year.

• 2.4L inline-four — DOHC, naturally aspirated, gasoline
• 2.7L V6 — DOHC, naturally aspirated, gasoline

Body styles covered

• 4-door sedan

Trims covered

• EX

Known issues on the 2008 Optima. Three recalls are on federal record for this model year. The first covers the frontal air bag system: the clock spring can develop high resistance, which the record ties to the driver's air bag in the event of a crash. The second covers the automatic transmission's column shift lever and linkage — the shift cable may have been installed incorrectly, with the risk arising if the driver leaves the vehicle without engaging the parking brake. The third covers the brake light switch: failure to illuminate the stop lamps during braking, or an inability to disengage the cruise control. Owners have filed 188 complaints for the year and Kia has issued 29 technical service bulletins. The factory diagnostic and repair procedures behind each of those systems are here.

Whether the job is tracing an air bag circuit fault, correcting a shift cable, or swapping a brake light switch, the 2008 Optima procedure you need is the one Kia wrote.
