Part A is a fan clutch. These are being used less and less but can still be found on many vehicles. This one is off of an 02 jeep with a 4.0. Common failures are one of three possibilities.

-The bearings will start to go out and the fan clutch will start to have some play.

-They will stay engaged all the time. If you have a vehicle with one and you hear the load roar at start up that goes away after a couple of seconds that’s the fan clutch. Imagine that sound all the time while the vehicle is running!

-last, they won’t engage at all. You would typically notice a hot or over heat issue at a stop.

Part B is a coil over style coil. This particular one is out of a late model, 4 Cyl, Volkswagen. When this part fails it will disable one cylinder as each cylinder has its on coil. For some reason these seem to fail a lot on the Volkswagens? We also see a fare share of them on the Ford pickups.

Part C is a coil pack. The difference between B and C is that a coil pack controls two cylinders at a time while a coil over type coil controls only one cylinder. This particular one has three individual coils in one package that control 6 cylinders. They can also be configured to have one coil that controls two cylinders (GM Cars, a four cylinder would require 2, a six cylinder would require 3, and an 8 cylinder 1would require 4) and two coils that control four cylinders (Ford 4 cylinders).

Part D is an inner tie rod. For some reason these have a high failure rate on the Taurus, Sable, and Windstar. Many of us are familiar with the outer tie rod which is threaded to the end of the inner tie rod. The inner tie rod is threaded onto the rack. Typically the inner tie rod is more labor intensive to replace and as a result usually cost more to replace. Just like an outer tie rod the inner will start to have some play in it when it starts to go bad. This one happens to be out of a 99 Sable.

Part E is the famous DPFE Sensor. These can be found on all Ford, Lincoln, and Mercury products except the Mercury Villager. (there may be other exceptions that I cant think of right now). DPFE stands for Delta Pressure Feedback of EGR. Its basically measures the difference in pressure between the two pipes that it is attached to. The two pipes come out of the EGR tube that runs into the intake. As more EGR gases flow through the pipe the more difference in pressure there is between the two pipes. When there is a problem the check engine light will come on. More often than not the DPFE sensor is the problem. Other issues can cause the same code like blocked EGR passages.
