It is rarely ever pleasant to hear an injector noise on your Chevrolet Colorado. It is a noise that comes up repeatedly, usually when you accelerate or your engine is idling. However, this sign may be related to several types of problems with your car injectors. It may not be anything serious, but when a frequent noise comes out, you have to be sure. Specifically since replacing your Chevrolet Colorado’s injectors can be costly. That’s why our team chose to write this content page in order to help you see more clearly, learn about the different plausible failures and distinguish your problem. To do this, we will first look at the normal running and usefulness of the injectors in your Chevrolet Colorado, then at the plausible triggers from which an injector noise may come.injector-noise-chevrolet-colorado

Functions of the injectors

Injectors are a very fundamental element of the operation of your engine unit. They were brought in to the modern cars about 20 years ago. Before their arrival, more conventional carburettor-type intake systems were used, which handled the intake of air and fuel into the engine cylinders. With the injectors, manufacturers now have the opportunity, thanks to the injectors pump, to control electronically each stage of the intake process very precisely (quantity of fuel injected, air/fuel mixture) via the analysis of the data accumulated from the various sensors equipping the car (engine temperature, acceleration level, engine speed, etc.). Their goal is therefore to inject under high pressure a precise quantity of an air/fuel mixture at a perfect timing to get the best possible combustion in the cylinders.

The different triggers of a clicking or knocking noise caused by the injectors of your Chevrolet Colorado

Discovering injector noises on your Chevrolet Colorado may result from different sources, we will now center on the potential triggers of these. In general, the regular noise of a faulty injector is of the snap type. Here are the different sources of these noises and the solutions to be adopted to stop them. If you hear another clicking noise but it is not from your injectors, we recommend you to read this content page about clicking noise on Chevrolet Colorado to locate the cause.

The explanations for injector clicking or knocking noise Chevrolet Colorado

A clicking or knocking noise from your injectors can be justified by different explanations. In fact, the injectors of your Chevrolet Colorado have three main missions, to manage the vaporisation of the fuel, i.e., to convert the liquid into “gas” during injection, to facilitate its combustion. Then, its task is to manage the air/fuel dosage and finally the homogeneity of the mixture, always with the target of improving combustion. If one of these three tasks is modified, the main functionality of the injectors will be disrupted and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders resulting from bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Chevrolet Colorado. The main cause of these situations generally originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible blockage will inevitably produce a malfunction of the injector. If after checking, this noise originates from another component of the engine of your Chevrolet Colorado, have a look at this content page for more infos.

The side effects of injector noise on Chevrolet Colorado

Now that we have reviewed the diverse reasons for injector noise on your Chevrolet Colorado, we will end by stating the possible effects of malfunctioning one or more of your injectors. Whether only one is clogged, or broken, or your entire fuel rail is involved, you cannot escape these consequences which can quickly become serious….
First, you risk destroying your exhaust system in the long run, because the unburned fuel residues that will end up in your exhaust system can corrode the metal in it.
One of the most basic repercussions noticed by drivers is a noticeable loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will surely have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will quickly harm your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks relating to your injectors and protect you from engine failure:

  • Do not drive at the bottom of the tank, as you may absorb impurities
  • Use quality fuel
  • Think of swapping your diesel fuel filter regularly>
