It is never enjoyable to hear an injector noise on your Cadillac Escalade. It is a noise that appears continually, usually when you accelerate or your engine is idling. However, this indication may be connected to different sort of concerns with your car injectors. It may not be anything major, but when a repeated noise shows up, you have to be sure. Specifically since fixing your Cadillac Escalade’s injectors can be costly. That’s why our team chose to create this content in order to help you see more clearly, learn about the different possible failures and establish your problem. To do this, we will first look at the normal running and usefulness of the injectors in your Cadillac Escalade, then at the possible causes from which an injector noise may come.injector-noise-cadillac-escalade

Benefits of the injectors

Injectors are a very fundamental element of the operation of your engine. They were brought in to the modern automobiles about 20 years ago. Before their appearance, more conventional carburettor-type intake systems were employed, which handled the intake of air and fuel into the engine cylinders. With the injectors, manufacturers now have the ability, 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 collected from the various sensors equipping the car (engine temperature, acceleration level, engine speed, etc.). Their aim is therefore to inject under high pressure a precise quantity of an air/fuel mixture at a perfect timing to obtain the best possible combustion in the cylinders.

The different reasons of a clicking or knocking noise based on the injectors of your Cadillac Escalade

Finding out injector noises on your Cadillac Escalade may originate from different locations, we will now look into the potential triggers of these. Generally, the regular noise of a faulty injector is of the snap type. Here are the several sources of these noises and the solutions to be applied to eliminate them. If you hear another clicking noise but it is not from your injectors, we suggest you to read this content about clicking noise on Cadillac Escalade to find the reason.

The explanations for injector clicking or knocking noise Cadillac Escalade

A clicking or knocking noise from your injectors can be explained for different explanations. In fact, the injectors of your Cadillac Escalade 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 control the air/fuel dosage and finally the homogeneity of the mixture, always with the objective of improving combustion. If one of these three tasks is modified, the main purpose of the injectors will be disturbed and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders as a consequence of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will induce thoses knocking or clicking noises on your Cadillac Escalade. The main reason of these trouble usually comes from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably result in a malfunction of the injector.

The consequences of injector noise on Cadillac Escalade

Now that we have reviewed the diverse causes for injector noise on your Cadillac Escalade, we will end by stating the possible side effects of malfunctioning one or more of your injectors. Whether only one is obstructed, or damaged, or your entire fuel rail is involved, you cannot escape these side effects which can almost instantly become considerable….
First, you risk destroying your exhaust unit 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 effects felt by drivers is a significant loss of power. In fact, if your engine is running on 3 out of 4 cylinders for example, you will inevitably have a loss of power
Finally, you risk deteriorating one of your pistons or your engine. Poor combustion will almost instantly affect your cylinders or pistons and your engine may tighten.
Here are three little suggestions to limit the risks associated with 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 changing your diesel fuel filter regularly>
