2003 Nissan 350Z Service and Repair Manual

This manual for the 2003 Nissan 350Z is built around one year, one engine family and one set of trims, so the torque values, wiring diagrams and service intervals inside are the ones Nissan published for a 350Z equipped with the 3.5L V6 (VQ35DE) rather than a generic figure pulled from a later refresh.

Known issues on the 2003 350Z. Four recalls are on federal record for this model year. The first covers aftermarket ZF Service replacement clutch kits fitted with an oversized clutch disc, which can let the car move unintentionally at start-up if the driver doesn't cover the service brakes. The second covers certain CK Motorsports replacement headlight and side marker lamps sold without amber reflectors, leaving the car poorly illuminated and at risk of a crash without warning. The third covers a fuel filler hose that can crack and leak fuel near an ignition source, raising the risk of fire. The fourth covers a crank or cam position sensor circuit board with an improper solder joint that can trigger the "Service Engine Soon" light, cause a no-start condition, reduced power, or a stall without warning. Owners have filed 275 complaints for the year. The factory diagnostic and repair procedures behind each of those systems are here.

From a stalling engine sensor to a fuel line inspection or clutch service, it keeps you on the OEM procedure and the correct specification for your specific 2003 350Z.
