You don't - its all done by the PCM (computer). Eric
There is no timing belt. Saturn Ion's use a timing chain.
The timing is controlled by the vehicle's computer. There is no need to adjust it during normal maintenance. I don't believe that it is possible to adjust the timing on that vehicle. I think that it was set and sealed at time of manufacture. Safest thing is to check with the dealer.
All vehicles without a distributor (which Saturn sc is one)can not have there timing adjusted(done by the computer).
Chain
no timing adjustment its all computer controlled
The SC2 is an 'S' series Saturn, and all 4 cylinder engines of the S series Saturn's used a timing CHAIN rather than a timing belt.
The 4 cylinder Saturn engines used an "Oil bath" timing chain. The V6 Saturn engines used an "external" timing belt.
The clutch pedal cannot be adjusted
use a laptop and the appropriate programs to adjust the timing via the car's ECU
The timing in a Saturn is not adjustable. The ignition timing is computer controlled by the Ignition control module located underneith your coil packs. if there is an issue with engine valve timing, you must replace all timing components, ie... timing cam gears, crank gear, hydralic tentioner and guides.
cant computer controled no adjustment
The V6 engine in a LS2 has a timing belt with replacement intervals at 100k miles
