2002 Cadillac Seville SLS Question: Humm????
Dose any one know where the spark plugs are located On My car??????? - Visitor
They are under the ignition coil assembly - which is located in the middle of the valve covers. Better if you get a manual for this car and understand the process clearly, or take it to a repair shop and ask them to replace them. Zee - ZeeTech
