The Holden Cruze coil pack is the part of the engine responsible for producing electricity, which is then used to power all of the electrical systems in your car. A defective coil pack can cause problems such as poor acceleration and difficulty starting and stalling. You need to replace your coil pack because if the spark plugs do not get enough power, they won’t work correctly. You will notice that your car needs help starting, especially on cold mornings.
What is the Holden Cruze coil pack?
A Holden Cruze coil pack is a part of the engine that supplies electricity to spark plugs. Pressing on your accelerator sends signals to your motor control module (MCM) and, ultimately, to each cylinder’s ignition coil. The MCM alerts each ignition coil to fire its spark plug simultaneously with all other cylinders in your engine.
When one or more cylinders fail to fire, a misfire will occur. It can cause many different symptoms depending on how many cylinders are affected by this problem:
- The car may idle unevenly or have trouble starting.
- There might be hesitation when accelerating.
- Some warning lights on your dashboard might come on.
You need to replace your Cruze coil pack if the engine misfires.
The engine will not start or run correctly. The Check Engine Light will be on, and you may notice the following symptoms:
- Your vehicle won’t start or drive when you step on the accelerator pedal. You may notice a hesitation in acceleration or a slight loss of power when driving at highway speeds. You also may hear engine noise when accelerating from any speed above 30 miles per hour (48 kilometres per hour).
- You hear an unusual sound from under your hood that continues when you turn off the engine and restart it again. It lasts only a short time before going away thoroughly after several minutes of driving at speeds greater than 40 miles per hour (64 kilometres per hour). If this happens more than once after restarting your vehicle, have it checked by a professional mechanic immediately!
The engine does not start.
Before replacing the ignition coil, we recommend checking if your car battery is in good condition. If not, you need to replace the battery and see if that fixes your problem.
In the case of a standard car battery, we suggest checking the starter by disconnecting its negative terminal and connecting it to an ignition source. Then try turning over the engine manually. If it turns over usually and smoothly, then there’s nothing wrong with your starter or starter relay; instead, the issue may be somewhere else on this list:
- Ignition switch
- Ignition coil (part of distributor)
- Fuel pump
- Fuel injectors
One of the most common problems with Cruze is a bad ignition coil.
The ignition coil is a magnetic device that generates current when the ignition switch is turned on. When you start your car, the coils pull in and amplify the voltage from your battery by creating an electromagnetic field that turns over your engine.
If you have any of these symptoms, likely, something isn’t right with your connection to your engine:
- Your car won’t start or only starts after long cranking.
- While moving, the engine stalls or dies.
- There are multiple clicks when turning on the key.
The ignition System is not working.
The engine does not start, or the engine starts but fails to run. When you turn off your ignition switch, you may hear a radio frequency interference noise from under the hood. If any of these occur, it indicates that one or more coils are failing and require replacement.
The engine starts but runs poorly. You may hear a clicking noise when you turn the key to start the engine, or your vehicle will not start at all.
The engine may stall when you accelerate or drive at higher speeds. The idle speed is rough, and it feels like the car is about to stall. The check engine light may be on or flashing, or there may be an electrical short in your ignition system.
Check Engine light is on.
If the check engine light is on, you should read your vehicle’s owner’s manual to determine what the code means and research how to fix it. The most common cause for this is a loose gas cap. When you go to the gas station, ensure you tighten your gas cap as much as possible before driving away from the pump.
If this doesn’t solve the problem or other codes are present when we check our car’s systems with an OBD-II scanner (or “diagnostic tool”), we need to replace the Holden Cruze coil pack.
The Holden Cruze is a small and often overlooked family car.
It’s an excellent car for families with small children as it has good safety features, but it’s also very reliable. It has a different reputation than some other vehicles in its class, and many people overlook this vehicle when looking to buy a new car.
The Holden Cruze was first released in 2008 and was designed by GM alongside the Daewoo Kalos. The model was built using an improved Opel Corsa platform with four-wheel drive capability added at the request of Australian consumers who wanted more traction on low-grip surfaces such as sand or mud and off-road driving capability.
The Holden Cruze was designed to be a competitor to the Toyota Corolla and Mazda3, but it quickly became clear that the car was much better than its competitors. It won many awards including the 2009 World Car of the Year award, Best Family Car from Wheels Magazine in 2010, Best Small Family Car from Auto Express in 2011, and many others.
Radio frequency interference.
Radio frequency interference is a common cause of several issues in cars. The issue is that the radio’s antenna picks up random signals from other sources, which are then transmitted to your car’s electrical system.
It can cause several problems with your engine, including the following:
- Your car may stall when you switch on the ignition.
- Your engine suddenly loses power or misfires while driving at high speeds or accelerating.
- A clicking sound is heard from the engine compartment when you turn on the radio and adjust its volume levels.
The radio volume fluctuates when you drive over bumps in the road. The radio reception is weak or static, even when you are in a clear area with no other cars around.
You can use the Holden Cruze Tools to check the problem with the Holden Cruze coil pack.
Using the Holden Cruze Tools to check the problem of the Holden Cruze coil pack is straightforward. The following steps are used to check the situation of the Cruze coil pack:
- Open the bonnet of your vehicle and locate the battery, which is located on top of a metal tray at the front of your engine bay.
- Locate two cables connected to clips on either side of your battery; these are known as terminals and should be labelled ‘+’ or ‘–’ depending on whether they can give or receive power respectively (i.e., if you connect something else with them, it will work). Identify which terminal corresponds with each cable attached in step 1 above – this may be difficult if there are other cables nearby but don’t worry too much, as we’ll discuss ways around this shortly!
- Use a multimeter to measure the voltage across each terminal by placing one end of the meter’s probes onto each. If you don’t have a multimeter, check that there is no visible damage on either cable and compare them to another set of wires known to be good; if they are damaged, you will need to replace them.
Conclusion
The good news is that you can replace a Cruze coil pack yourself. The bad news is that it will require some tools and expertise. Overall though, this is a relatively simple process that most people can do on their own if they’re willing to invest some time into learning how to do it.
