The power of Cadillac DTS vehicles relies mainly on the Spark Plug that ignites the air-fuel mixture required for the engine combustion. It works by contributing a high voltage electrical energy from the ignition system it produce a spark that lead to the burning of the mixture hence contributing to the formation of the combustion pressure that pushes the piston. Cadillac DTS models have used many types of Spark Plugs include copper/nickel, platinum, double platinum and Iridium plugs depending on ignition systems and performances. Most of the differences that we can observe between these Spark Plugs are related to the material they are made of and their resistance. Copper/nickel plugs are generally employed in older ignition systems because these have lower operating temperature, on the other hand, platinum and iridium plugs are longer lasting and provide improved performance at higher temperatures. These are the double platinum plugs which are suitable for Distributor-less Ignition Systems (DIS) to give long service and high performance.
Cadillac DTS Spark Plug Parts Questions & Experts Answers
- Q: How to replace spark plugs and ensure proper installation on Cadillac DTS?A:Start the Ignition Coil replacement procedure by removing the specific Ignition Coil based on whether it belongs to bank 2 or bank 1. Wait until the engine has cooled down before touching spark plugs to stop the damage of Cylinder Head threads. Thoroughly clean the Spark Plug recess area using a thread chaser after which you should check the seating area to prevent contamination from affecting plug placement. Thorough inspections should be performed on spark plugs while they remain in their engine position (Spark Plug Inspection). Installation of new spark plugs needs to use items that conform to the vehicle specification exactly since using different heat levels can result in engine damage. Use a round feeler gauge to inspect the gap of new and reconditioned spark plugs since handling may have changed the pre-set gaps then compare the results against the specifications in the ignition system specifications to make any necessary adjustments. The thread chaser enables easy and complete insertion of the Spark Plug into the Cylinder Head to prevent overheating and thread damage. Fasten the proper Ignition Coil after tightening the Spark Plug(s) to 15 n.m (11 lb ft). In case of bank 1 use Ignition Coil replacement - bank 1 and bank 2 requires Ignition Coil replacement - bank 2.
