If it ain't broke, don't fix it. Replacing all of the above described items certainly seems like it would prevent the possibility of them failing at some point in the future, but if they're all working, why replace them. I was still running on the original injectors, coil pack and control valves on my American built vehicle with over 150,000 miles when I traded it in for a new car. It sounds like a dealer is trying to milk you for whatever they can get. However, maybe they know something that the rest of us don't; maybe those parts tend to fail on that particular vehicle. Either way, I don't think I'd replace all of those parts as routine maintenance.
No, diesel common rail systems do not use coil packs. Coil packs are typically associated with gasoline engines that use spark ignition, where they provide the necessary spark to ignite the air-fuel mixture. Diesel engines, on the other hand, rely on compression ignition and use fuel injectors to deliver fuel into the combustion chamber at high pressure.
change the injectors you could have plugged injectors.
Make sure your Truck is in good maintenance. New plugs, air filter, fuel filter etc. Then check engine codes. Also may want to check coil packs, injectors and give a compression test.
Desiccant Packs are use to control moisture, humidity, mold and mildew. These Desiccant Packs are USFDA Arpprove and fill with Silica gel, Molecular Sieve, Activated Clay and Carbon.
both the 3100 and 3800 series engines have the ignition control module mounted under the coil packs. remove the coil packs and there it is.
there is no distributor. it uses coil packs and control modules
No. The coil packs can be removed without taking the fuel rail off.
The ignition control module is located on the left side of the engine, it is what the coil packs are attached to. If you remove both coil packs and unplug the two connections it will come right off.
It's not advisable to leave a hydrocollator off with hot packs submerged in cooler water for several days. The packs may not maintain their therapeutic heat and could become damp or develop bacteria. It's best to keep the hydrocollator on to ensure the packs remain properly heated and hygienic for use. Regular maintenance will help prolong the life of the hot packs.
no you can get sick
no.... check the fuel injectors, and the distributor set (or coil packs)
The plate that coil packs are placed on is typically called a "coil pack mounting plate" or simply a "coil pack plate." It provides a secure mounting location for the coil packs on the engine.
