Chevrolet Colorado Ignition Coils

 

The Chevrolet Colorado comes with three different types of engines. A 4 Cylinder, a 5 Cylinder, and a 6 Cylinder engine. Each type of engine uses the ignition coil on plug distributor-less ignition setup. When one coil fails, and the rest are old, it's more cost efficient to replace all of the coils at the same time. Pay attention carefully to the year and some later years of the same generation use different type of ignition coils. We have what you need at the price you've been looking for. Not to mention a lifetime warranty, and free shipping. We also allow a full 2 months to return any new, unused ignition coils without question, and we dont' charge restocking fees. There is a number of reasons why the coils can fail in the Colorado, and th two most common reasons? Old Spark plugs and bad grounds/arching your tools while wrenching. Arching happens while working on electrical components like the batters, alternator, or starter. It's easy to accidentally touch the metal part of your ratchet to a power source causing sparks. This is called "arching". In my years of working on vehicles, I have personally made this mistake. While accidentally arching your tools can cause damage to other components, it doesn't always happen. The ignition coils are usually the first to take on damage when this happens. As far as old spark plugs go, old spark plugs have large gaps. The electrode wears down, increasing the gap between the tip of the spark plug. This increases resistance, and forces the ignition coil to work harder to do the same job. Other causes of failure are the typical: improperly washing your engine bay, leaky center valve cover gaskets that leak oil into the spark plug holes, damaging both the spark plug and ignition coil. if you live in a humid state, the coils will not last as long as your friend who lives in a state like Arizona. The last reason that is not really a big reason, but more of an observation from us is design. Some manufacturer's design of their ignition coils do not last a long time. Fortunately The Chevy Colorado didn't have an issue with this.

Replacing Ignition Coils in Your Chevrolet Colorado

 

This is fortunately quite easy with this vehicle for most mechanics with basic wrenching experience. Each coil is held on with a 10mm bolt, and comes off without much work. Diagnosing which coil is bad is easy as well. If you have a code P0301 though P0306, OR common codes with the Colorado are P0351 through P0356 indicating an ignition coil circuit problem. This type of code can show up for a bad ignition coil. Simply swap the coil pack form the misfiring cylinder over to another cylinder to see if there is a change. If the misfire code changes, then the problem is with the ignition coil packs. If the code does not change, then the problem is with something else. Doing this will prevent you from spending money on parts that were never bad in the first place.
