Sluggish hot starts after a battery and cable replacement
Devil Boy’s 997 still cranked sluggishly when hot after a new battery and starter/alternator cable. He then replaced the starter and reported much quicker starts, with hot starting no longer an issue. He put the job at about 2.5 hours. This is his reported result, without a stated follow-up duration or a confirmed diagnosis for every slow-cranking 997.
Clearing access through the intake
The author began by disconnecting the battery, then removing the airbox, throttle body and intake plenum. He described four E10 throttle-body bolts and loosening the intake clamps with a 7 mm socket. The tuning pipe also came out after disconnecting the small vacuum line behind it. He moved the air/oil separator hoses aside to make room for his hands and tools.
Reaching the starter fasteners
Devil Boy disconnected the starter leads using 13 mm and 10 mm sockets. The starter had two E14 mounting bolts, at the upper right and lower left. He reached them with a 24-inch extension and a universal joint held at the needed angle with tape, using a breaker bar for the initial release. He approached the lower bolt from a lower angle before removing the starter.
The replacement and the reported torque
The author used a remanufactured starter identified as part 12446 in his account. He wrote that the mounting bolts were tightened to 33 ft-lb according to a workshop manual. That value and identifier are retained as his source statements; they have not been independently verified as the correct specification or fitment for another 997. His historical purchase does not establish current availability or price.
Restoring the vacuum line and intake connections
After cleaning and reconnecting the starter leads and refitting the separator hoses, Devil Boy reconnected the small vacuum line behind the tuning pipe. He used the yellow witness mark to check the connection and the locating tabs to check the rubber tubes were centered. He left the plenum clamps partly loose until the throttle body was aligned with its rubber bumper and bolted in place, then tightened the clamps, reconnected the hose and electrical connector, and refitted the airbox before reconnecting the battery.
