A Comprehensive Guide to the Ignition Contact Set for the 1965-1972 Dodge Coronet
Keep your classic Coronet's ignition firing reliably with the right parts and knowledge.
- The ignition contact set (points) is a critical wear item on 1965-1972 Coronets that requires regular replacement.
- Symptoms of failure include no-start conditions, rough idling, and misfiring.
- Always replace the condenser at the same time as the points to prevent premature failure.
- Using a premium aftermarket brand like Standard Blue Streak is recommended for better durability and performance.
Understanding the Heart of Your Coronet's Ignition
For owners of a classic 1965-1972 Dodge Coronet, the ignition contact set is a regular maintenance item that is key to engine performance. Unlike modern cars with electronic ignition, your Coronet relies on this mechanical system to time its spark. These points wear down over time from the constant opening and closing, and the rubbing block that rides on the distributor cam wears, changing the ignition timing and dwell. Regular inspection and replacement are essential for a smooth-running engine.
Symptoms of a Failing Ignition Contact Set
When your ignition points start to fail, the symptoms are often very noticeable. You don't have to be a master mechanic to spot the signs. Being aware of these can save you from being stranded.
- Engine Won't Start: The most severe symptom is a no-start condition. The engine will crank over but won't fire up because the points are not triggering the coil to create a spark.
- Rough Idle and Poor Running: As the points wear or become pitted, the engine may run rough, misfire, or hesitate during acceleration. This can sometimes get worse as the engine warms up.
- Engine Stalling: Worn or improperly gapped points can cause the engine to stall, especially at idle. The connection can become erratic, leading to a loss of spark.
A Note on "New OEM" Parts
Finding a true "New Old Stock" (NOS) Mopar ignition contact set for a vehicle of this age is very difficult and often expensive. The market primarily consists of aftermarket parts. Fortunately, reputable aftermarket brands have been making these components for decades and offer excellent quality.
Choosing the Right Aftermarket Ignition Contact Set
With only one primary brand available, the choice comes down to the quality tier. Standard Motor Products (SMP) is a long-standing, reputable manufacturer of ignition components. They offer different product lines for your Coronet.
- Standard (Red Box): This is their standard replacement line. It offers good quality that meets or exceeds original specifications and is a reliable choice for a daily driver or stock restoration.
- Standard Blue Streak: This is SMP's premium line. Blue Streak points are often built with higher quality materials, such as a ventilated design and a rubbing block made for longevity. Many classic Mopar enthusiasts prefer Blue Streak parts for their durability and consistent performance. Given the small price difference, opting for the Blue Streak set is a worthwhile investment for peace of mind.
Pro Tip: Always replace the condenser when you replace the ignition points. A failing condenser is a common cause of premature point failure. Most quality contact sets are sold as a kit that includes a new condenser.
Typical Costs for Replacement
The cost to replace an ignition contact set is very reasonable, especially if you do the work yourself. The parts are inexpensive, and the labor is straightforward for those familiar with older cars.
| Part/Service | Estimated Cost |
|---|---|
| New Aftermarket (Standard/Blue Streak) | $16.49 - $34.07 |
| Shop Labor | $75 - $150 |
Frequently Asked Questions (FAQ)
How often should I replace my ignition points?
As a general rule, ignition points should be inspected at every oil change and replaced as part of a tune-up every 10,000 to 20,000 miles. The rubbing block wears down over time, which closes the point gap and retards ignition timing, so regular checks are important for performance.
What tools do I need to replace my ignition points?
You will need basic hand tools like a screwdriver and wrenches to remove the distributor cap. To properly set the new points, you will need a feeler gauge to set the gap and, ideally, a dwell meter to verify the setting. You should also have a small amount of distributor cam lubricant.
What is the difference between points and electronic ignition?
Points are a mechanical switch, while electronic ignition uses a magnetic pickup (reluctor) and a control module to trigger the coil. Electronic systems have no moving parts that wear out, so they are more reliable, require less maintenance, and provide a more consistent spark, especially at high RPM. Many owners of classic cars convert to electronic ignition for these reasons.
Are there any recalls or TSBs for my Coronet's ignition points?
No. There are no active recalls or Technical Service Bulletins (TSBs) from the NHTSA for the ignition contact set on a 1965-1972 Dodge Coronet. Recalls found for Dodge ignition systems apply to much newer vehicles with modern electronic components.
Technical Specifications
Mechanical breaker points system. Requires a specific gap setting (e.g., 0.017 inches) which translates to a dwell angle (e.g., 30 degrees). Always use cam lubricant on the rubbing block.
