Ford AGSF-32Y-PC Spark Plug

While replacing spark plugs, put silicone dielectric compound inside all spark plug wire boots and terminals. Use a gap gauge together with a ratchet, extensions, and a spark plug socket. Check and adjust the gap on the new plugs. If necessary, detach the electrical connector and then remove the spark plug wire. Clean out any debris from the spark plug hole using compressed air. Older models can be compared to a chart when removing old plugs with a spark plug socket. Apply anti-seize compound to threads of the new plug before threading it into the hole. Examine it first before connecting a new spark plug wire. Change other plugs one by one in a similar way as explained above.

The serpentine drive belt plays a crucial role in various engine components' operation, such as the alternator, power steering pump, water pump (for four-cylinder models), and air conditioning compressor.

Disconnect each wire from the spark plug and ignition coil pack or distributor one at a time, checking for secure fitment and corrosion, and replace any damaged wires as needed.

Tensioner replacement requires removing the drive belt, and the process varies for four-cylinder and V6 engines, depending on the model year. It is important to ensure proper tightening of tensioner bolts during reinstallation.
