2011 Kia Optima Service and Repair Manual

Every specification and tightening sequence in the 2011 Kia Optima factory service and repair manual is the one Kia published for this exact year, engine and trim, not a near-enough figure carried over from an adjacent model year — so what you set on the car is what the factory intended for it.

Known issues on the 2011 Optima. Four recalls are on federal record for this model year. The first concerns the engine itself and traces to machining errors during the engine manufacturing process: bearing wear may result in the engine seizing, increasing the risk of a crash. The second is filed against the hydraulic anti-lock brake and traction control system, where an engine compartment fire while parked or driving can increase the risk of injury. The third covers the fuel delivery hoses, lines and fittings on vehicles that previously received an engine replacement under that first engine recall — a fuel leak in the presence of an ignition source can increase the risk of a fire. The fourth covers the brake light switch: the stop lamps can fail to illuminate during braking, or the cruise control may not disengage. Owners have filed 769 complaints for the year and Kia has issued 169 technical service bulletins. The factory diagnostic and repair procedures behind each of those systems are here.

From checking bearing clearances after an oil-pressure warning to tracing a stop-lamp switch fault or a scheduled service on the 2.0L turbo or the Hybrid, it keeps you on Kia's own procedure and the correct specification for your 2011 Optima.
