Chevy 350 Ignition Coil Location And Everything About Them
Fixing the ignition coils is essential when you experience issues like engine misfire and the Check Engine light that won’t go off. However, finding them might be challenging if you don’t have any prior knowledge.
So, do you have an idea of the Chevy 350 Ignition coil location in your car? It would be right beneath the fuel pressure regulator. The ignition coils are situated close to a valve cover on the Chevy 350. Each spark plug normally has a coil-on-plug ignition coil positioned next to or immediately above it.
Thus, to reach the coils, unscrew the plastic engine protectors and the inlet air tubes. However, the answer doesn’t end here if you have very little knowledge about the engine. You certainly need to know the location when you need to change them.
Hence, a simple chart is given below that will help you with identifying a bad coil;
Symptoms | Reason |
Having Trouble Starting The Engine | Not enough voltage is provided by the malfunctioning coils |
Engine Stuttering Or Misfiring | Uneven sparks from the spark plug cause the engine to stall |
The Smell Of Gas | Engine misfiring causes emissions as the engine is under more stress |
Low Mileage | The system will try to compensate for the weak spark plugs by pumping additional gasoline |
Check Engine | The engine identifies that there is something wrong with it |
Why Ignition Coils Are Important?
The ignition coil also referred to as a spark coil, aids in the starting of a car’s engine. It is a critical component of the ignition system. Although a vehicle’s battery has only 12 volts, it takes thousands of volts to ignite the spark plug. This is the importance of these coils.
It is a small transformer that turns the automobile battery’s 12 volts into thousands of volts as required. Thus, the energy from the ignition coil is required for the spark to create the requisite spark for combustion. If there is no combustion, your automobile will not even start!
Symptoms Of A Bad Ignition Coil
Before you even think about searching for the ignition coils and laying your hands on them, make sure it’s a bad one. The indications are clear signs that would help you identify them. So here are the signs of bad ignition coils that will ensure you that you have a bad one;
Having Trouble Starting The Engine
A faulty ignition coil might be the source of your car’s engine starting problems. If you have a large number of faulty ignition coils, you may encounter malfunctioning ignition with difficulty starting your car.
However, there are a variety of various issues that might make it challenging for an engine to start. Also, difficulty in starting the engine by itself isn’t sufficient to prove a coil issue.
Engine Stuttering Or Misfiring
Your ignition coil may be defective if your engine stutters or misfires while you are idling, stopping quickly, or accelerating. A misfire indicates that one of the engine’s cylinders is not firing properly. Moreover, you might hear a spitting or sputtering noise or feel like a jerk or severe vibration.
Due to the malfunctioning ignition coil, uneven sparks from the plugs cause the automobile to stall.
Smell Of Gas
Concerning the last symptom, misfires can cause emissions and are also more likely to happen when the engine is under stress. Increased emissions and a gas-like odor coming from the exhaust are signs of a faulty ignition coil.
Low Mileage
If you notice that your car gets lower mileage than normal with a full tank of gas, you may have a faulty ignition coil. This happens when the system tries to compensate for the weak spark plugs by pumping additional gasoline.
Check Engine
The check engine light’s purpose is to alert you to an issue with the engine. Your check engine light will detect the ignition issue if you are traveling and turn it on. Hence, the check engine light should never be ignored. However, it could also be a sign of several various engine issues.
Chevy 350 Ignition Coil Location
As soon as you open your engine bay, you come across your Chevy 350 engine. Here, you will come across a plastic that covers a portion of the engine. It is meant to be unscrewed.
You would need a small flat-blade screwdriver to unscrew the bolts properly. However, always take care of yourself by taking precautions such as using protective gloves. Also, don’t forget to remove the negative battery cable first so that you don’t hurt yourself.
Accordingly, while you get access to the engine’s insights, you will come across a fuel pressure regulator that stands out from the rest. That is easy to identify. Then, you will come across four ignition coils that are directly linked to the spark plugs right beneath the regulator.
On the other hand, you might also need to take care of the inlet tubes and you have to unplug those before you get your hands on them.
Frequently Asked Questions (FAQs)
Hope you have got your answer now. It’s time for the FAQ section where we brought up questions from Chevy 350 users and answered them in short. So let’s take a look at them as well.
The ignition coils are responsible to make the engine start. Without the proper amount of energy that the ignition coils would have given, it’s impossible to start any engine.
Swapping parts is an easy approach to determining whether the problem is with the coil or the spark plug. Connect the suspicious ignition coil to a new plug with new wiring as you’ll probably need to change them anyhow. If it still won’t ignite, the coil is to blame.
It may have an excessively high resistance or have a gap in the middle of the circuit if there are wires connecting the spark plug and the coil pack. If the coils are connected directly to the plugs, the contact surfaces are damaged, and the misfire will persist.
Conclusion
To conclude, that was all for our chevy 350 ignition coil location and everything you needed to know about them. As soon as you identify the fuel pressure regulator, you will be able to easily identify the ignition coils. It’s right beneath them.
On the other hand, don’t take bad ignition coils for granted. They play a significant role in the engine and you shouldn’t play with a bad one. Always look out for the symptoms such as Check Engine lights on or continuous misfires by the engine.
