Saturn Relay 2005-2007 Starter Motor: A Complete Replacement Guide
A single click when you turn the key is a classic sign of starter failure on your Saturn Relay; here's how to fix it.
- A single, loud click with no engine crank is the most common symptom of a failed starter on the Saturn Relay.
- Before replacing the starter, always check for a weak battery and clean, tight battery connections first.
- This is a DIY-friendly repair for those with basic tools; the starter is held by two bolts and is relatively easy to access.
- A brief period of continued cranking after releasing the key is a normal, computer-controlled feature and not a defect.
Is Your Saturn Relay Starter Failing?
When a starter motor begins to fail, it can leave you stranded without warning. For the 2005-2007 Saturn Relay, the symptoms are usually straightforward. Understanding these signs can help you decide if it's time for a replacement.
Check the Simple Things First
Before blaming the starter, make sure your battery is fully charged and the battery terminals are clean and tight. A weak battery or poor connection is the most common reason for a no-start condition. Many starting issues can also be traced to fuses or relays in the underhood fuse box.
Common Failure Symptoms
- Single, Loud Click: The most common symptom for these vans. You turn the key, and all you hear is one loud click from the engine bay. This sound is the starter's solenoid engaging, but the motor itself fails to turn, indicating a high probability of starter failure.
- No Sound at All: If you turn the key and nothing happens, the problem could be the starter, but it's also very likely to be a dead battery, a bad ignition switch, or a failed starter relay.
- Grinding Noise: If you hear a metallic grinding sound during or after cranking, it could be the starter gear failing to engage or disengage properly with the engine's flywheel. This can also indicate worn teeth on the flywheel itself.
- Intermittent Starting: The van starts fine one day but won't crank the next. This often points to a developing electrical issue within the starter motor, such as worn brushes or a bad spot on the motor's windings.
Choosing the Right Aftermarket Starter
You don't need to buy a part from a dealership to get your Relay running reliably again. Quality aftermarket brands offer excellent performance and value. For this part, the choice between OEM and a quality aftermarket part is not a major concern, as top aftermarket brands produce reliable units.
Brand Quality Tiers
- Premium Aftermarket (ACDelco Gold/Professional): ACDelco is General Motors' own parts brand, and their top-tier parts are considered a benchmark for quality. These are typically all-new units, not remanufactured, and are built to meet or exceed original factory specifications. Expect excellent fit and long-term reliability.
- Quality Aftermarket (MPA, ACDelco Silver): Brands like MPA (Motorcar Parts of America) specialize in starters and alternators. They produce high-quality new and remanufactured parts that are rigorously tested. These brands offer a great balance of price and performance, providing a dependable repair without the premium price tag.
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket Starter | $56 - $192 |
| Shop Labor | $120 - $200 |
| Total Estimated Cost | $176 - $392 |
A Note on Remanufactured Parts
A remanufactured starter is an old unit that has been rebuilt with new components to fix common failure points. A quality remanufactured part from a reputable brand like MPA or ACDelco can be just as reliable as a new one and is a good, cost-effective option.
Frequently Asked Questions
My engine keeps cranking for a second after I let go of the key. Is my new starter bad?
No, this is a normal and documented feature of your Saturn Relay and other GM vehicles from this era. The engine's computer (PCM/ECM) controls the starter. Once you hold the key in the 'start' position for a moment, the computer takes over and will crank the engine until it starts or until a set time limit is reached, even if you've already released the key. This is not a fault with the starter.
Can I replace the starter myself?
Yes, this is a job that a DIYer with basic tools can accomplish. The starter is accessible after removing a small cover. It is held on by two bolts and has three wire connections. Always disconnect the battery's negative terminal before beginning any work on the starter to prevent electrical shorts.
Is a 'no-start' problem always the starter motor?
No. A no-start or no-crank condition can be caused by many things. The most common culprits are a weak battery, corroded battery terminals, a bad starter relay, a blown fuse, or a faulty ignition switch. Some owners have also reported that the vehicle's security system can prevent it from starting. Always diagnose the simple things first.
Are there any recalls for the starter on the Saturn Relay?
No, there have been no recalls issued by the NHTSA or General Motors for the starter motor on the 2005-2007 Saturn Relay. Recalls for this vehicle were related to other issues like seat latches and labels.
