It is never relaxing to listen an injector noise on your Cadillac SRX. It is a noise that arises frequently, usually when you accelerate or your engine is idling. However, this symptom may be relating to different kind of problems with your car injectors. It may not be anything major, but when a persistent noise appears, you have to be sure. Most importantly since replacing your Cadillac SRX’s injectors can be costly. That’s why our team chose to compose this content in order to support you see more clearly, learn about the different conceivable failures and identify your issue. To do this, we will first look at the normal function and usefulness of the injectors in your Cadillac SRX, then at the conceivable triggers from which an injector noise may come.injector-noise-cadillac-srx

Attributes of the injectors

Injectors are a very significant component of the operation of your engine motor. They were launched to the modern automobiles about 20 years ago. Before their arrival, 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 obtained from the various sensors equipping the car (engine temperature, acceleration level, engine speed, etc.). Their objective 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 origins of a clicking or knocking noise coming from the injectors of your Cadillac SRX

Experiencing injector noises on your Cadillac SRX may result from different locations, we will now look into the potential causes of these. In most cases, 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 implemented to get rid of them. If you listen another clicking noise but it is not from your injectors, we suggest you to go through this content about clicking noise on Cadillac SRX to find the cause.

The explanations for injector clicking or knocking noise Cadillac SRX

A clicking or knocking noise from your injectors can be explained for different explanations. In fact, the injectors of your Cadillac SRX have three main missions, to control the vaporisation of the fuel, i.e., to transform the liquid into “gas” during injection, to facilitate its combustion. Then, its task is to manage the air/fuel dosage and at last the homogeneity of the mixture, always with the objective of improving combustion. If one of these three features is altered, the main role of the injectors will be disrupted and this will lead to poor combustion. This bad combustion will be a violent explosion in the cylinders because of bad timing, or a bad quantity of mixture or finally an inhomogeneous mixture and will provoke thoses knocking or clicking noises on your Cadillac SRX. The main cause of these problems usually originates from a particle that gets into the injectors. The precision of the injector being in the nanometer range, any possible obstruction will inevitably end in a malfunction of the injector. If after checking, this noise originates from another component of the engine of your Cadillac SRX, have a look at this content for more informations.

The side effects of injector noise on Cadillac SRX

Now that we have examined the different causes for injector noise on your Cadillac SRX, we will end by stating the possible end result of malfunctioning one or more of your injectors. Whether only one is obstructed, or broken, or your entire fuel rail is involved, you cannot escape these side effects which can quickly become critical….
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 known effects felt 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 obviously have a loss of power
Finally, you risk degrading one of your pistons or your engine. Poor combustion will quickly damage your cylinders or pistons and your engine may tighten.
Here are three little tips to limit the risks connected 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>
