A Guide to the Starter Motor for the 2005-2007 Mercury Montego
If your Montego won't crank or is slow to start, the starter motor could be the reason; here is what you need to know.
- The most common symptoms of a failing starter are a slow crank, a single click, or no crank at all.
- Always test the battery and check fuses/relays before replacing the starter; these are common and cheaper failure points.
- A new aftermarket starter from a brand like MPA provides a good balance of cost and reliability for your Montego.
- Replacement is a feasible DIY job, but accessing the starter, which is on the back of the engine, can be challenging.
Is Your Montego's Starter Failing?
A failing starter rarely dies without warning. Before it fails completely, you will likely notice one or more symptoms. Always check that your battery is fully charged and the terminals are clean before suspecting the starter, as a weak battery can cause similar issues.
Don't Ignore a Grinding Noise
A grinding noise during startup is a serious symptom. It often means the starter gear is not meshing correctly with the engine's flywheel. Continuing to crank the engine can cause severe damage to the flywheel, a much more expensive and difficult repair than replacing the starter itself.
Choosing a New Aftermarket Starter
When replacing the starter on your Montego, you have several options. An OEM (Original Equipment Manufacturer) part from Ford is the most expensive choice. A used OEM starter from a salvage yard is a cheaper but risky alternative, as its history and remaining lifespan are unknown. For most owners, a new aftermarket starter offers the best balance of quality, price, and reliability. Brands like MPA (Motorcar Parts of America) produce new aftermarket parts that are designed to meet or exceed original specifications, providing confident cranking performance without the high cost of an OEM part. These new parts are often a better value than remanufactured units, which are rebuilt from used components.

Pro Tip: Check the Starter Relay First
Sometimes a no-crank, no-start issue can be caused by a simple, inexpensive starter relay. On the Montego, these relays are located in the under-hood fuse box. A quick wiggle and push on the relays has been known to solve the problem for some owners. 🎬 Watch: How to fix a no-start issue with a simple relay check. If that doesn't work, swapping the starter relay with an identical one from a non-essential system (like the horn) can be a quick diagnostic test.
Known Issues & Recalls
The 2005-2007 Mercury Montego and its sibling, the Ford Five Hundred, do not have any specific recalls or Technical Service Bulletins (TSBs) directly related to starter motor failure. However, owners on forums have reported issues with grinding noises and improper gear engagement, sometimes even after replacing the starter. This may point to a potential alignment issue that can sometimes be corrected with shims. There are also reports of no-crank conditions that can be traced back to fuses or relays rather than the starter motor itself.
Frequently Asked Questions (FAQ)
Where is the starter located on a 2005-2007 Mercury Montego?
The starter motor is located deep on the backside of the 3.0L V6 engine, near the transaxle. Access requires removing the air cleaner box assembly to create working space from the top 🎬 See this walkthrough for accessing the starter on the 3.0L engine. of the engine bay.
Is replacing the Montego starter a difficult job?
It is a moderately difficult job for a DIY mechanic. While it doesn't require highly specialized tools, accessing the starter bolts can be tricky due to the tight space. You will need tools like an 8mm, 10mm, and 13mm socket, along with extensions and possibly a swivel adapter. Several owners and mechanics have noted that getting to the bolts is the hardest part of the job.
What are the main symptoms of a bad starter on the Montego?
The most common symptoms are a slow, struggling engine crank, a single loud click when you turn the key, 🎬 Watch: A quick hack for a starter clicking but not cranking. or no sound and no crank at all. You may also hear a grinding or whining noise, which indicates a serious problem that should be addressed immediately.
Could my starting problem be something other than the starter?
Yes. Always check the battery first. A dead or weak battery is the most common cause of starting issues. Also, check the battery cable connections for corrosion. A faulty ignition switch, starter relay, or even the anti-theft system can also prevent the car from starting.
