Is It Time For A Subaru Ignition Coil Replacement?

Your Subaru engine relies on a strong spark to ignite the air-fuel mixture for correct combustion and smooth operation. A weak or failing ignition coil makes your vehicle run poorly, leading to frustrating performance issues and potential damage over time. The Subaru ignition coil replacement process restores power and efficiency to your engine so you avoid costly repairs later on. You often notice strange symptoms when a coil begins to fail and require a quick diagnosis.

Common Symptoms of a Failing Subaru Ignition Coil

A failing ignition coil often presents with very clear and distinct symptoms you notice during everyday driving. You may experience a rough idle where the car shakes or vibrates when it sits still at a stoplight. You will feel a significant loss of power or hesitation when you try to accelerate on the highway. A flashing check engine light on your dashboard warns you about engine misfires and suggests an urgent problem. These are all signs your Subaru ignition coil is ready for replacement.

How to Test a Subaru Ignition Coil

Testing a Subaru ignition coil requires a few simple tools and a careful approach to ensure you get accurate results. You start by using a multimeter to measure the resistance across the primary and secondary windings of the coil. The results of the multimeter test tell you if the coil works correctly or if it has an internal short circuit. You can also use a spark tester to check for a strong spark at each individual spark plug. These two methods together help you confirm a failing coil.

Steps to Replace a Subaru Ignition Coil

Replacing a Subaru ignition coil is a straightforward process you can perform at home with basic hand tools. First, you disconnect the negative battery cable to prevent any electrical shocks during the repair. Then you remove the coil's mounting bolts and disconnect the electrical connector from the wiring harness. You install the new coil in the reverse order, making sure you connect all wires and bolts securely for safe operation. Remember to clear any engine codes with an OBD-II scanner.

Cost of Subaru Ignition Coil Replacement

The cost of a Subaru ignition coil replacement varies depending on your specific Subaru model and where you buy your parts. Individual coils can range from $50 to $150 each, so the total cost changes if you need to replace just one or all of them. The labor costs for a professional installation also add to the final price. These prices are often much less than the cost of a complete engine repair or other serious damages caused by a failing ignition coil.

Preventative Maintenance for Subaru Ignition Coils

Preventative maintenance helps you extend the life of your Subaru ignition coils and keeps your engine running smoothly for many years. You should replace your spark plugs at their recommended intervals and use quality parts to reduce strain on the ignition system. You also inspect the wiring and connectors around the coils for any signs of wear or damage that could lead to future problems. A properly maintained ignition system saves you from unexpected breakdowns and costly repairs.
