It is hardly ever enjoyable to listen to an injector noise on your GMC Savana. It is a noise that comes up continually, usually when you accelerate or your engine is idling. However, this sign may be related to several types of concerns with your vehicle injectors. It may not be anything serious, but when a frequent noise happens, you have to be sure. Most importantly since replacing your GMC Savana’s injectors can be costly. That’s why our team chose to produce this article content in order to support you see more clearly, learn about the different conceivable failures and distinguish your trouble. To do this, we will first look at the normal running and usefulness of the injectors in your GMC Savana, then at the conceivable causes from which an injector noise may come.
Benefits of the injectors
Injectors are a very important part of the operation of your engine. They were launched to the modern vehicles about 20 years ago. Before their appearance, 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 received from the various sensors equipping the vehicle (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 coming from the injectors of your GMC Savana
Listening injector noises on your GMC Savana may result from different origins, 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 origins of these noises and the solutions to be adopted to eliminate them. If you listen to another clicking noise but it is not from your injectors, we encourage you to browse this article content about clicking noise on GMC Savana to find the cause.
The explanations for injector clicking or knocking noise GMC Savana
A clicking or knocking noise from your injectors can be explained for different explanations. In fact, the injectors of your GMC Savana 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 mission is to control the air/fuel dosage and at last the homogeneity of the mixture, always with the aim of improving combustion. If one of these three characteristics is altered, 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 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 GMC Savana. The main cause of these problems generally comes from a particle that gets into the injectors. The accuracy of the injector being in the nanometer range, any possible obstruction will inevitably produce a malfunction of the injector.

The consequences of injector noise on GMC Savana
Now that we have analyzed the several causes for injector noise on your GMC Savana, we will end by stating the possible end result of malfunctioning one or more of your injectors. Whether only one is blocked, or damaged, or your entire fuel rail is involved, you cannot escape these side effects which can quickly become major….
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 consequences 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 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 linked 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 changing your diesel fuel filter regularly>
