You turn the key, the dashboard lights up, and you expect a smooth purr. Instead, you feel a vibration rattling through the steering wheel or hear a clunk when you shift gears. If this sounds familiar, your Honda Accord might be trying to tell you something about its engine mounts.
But before you dive into repairs or order parts, you need to know exactly what you're dealing with. A common question for DIY mechanics and car owners alike is: exactly how many mounts are holding that engine in place? The answer isn't as straightforward as a single number, as it depends heavily on the year, engine type, and transmission of your specific Accord.
In this guide, we’ll break down the engine mounting configurations for the Honda Accord, identify the signs of a failing mount, and help you understand what parts you might need to get your ride back to its smooth, reliable self.
The Honda Accord uses a sophisticated system of mounts to secure the engine and transmission to the vehicle's chassis. These aren't just simple metal brackets; they are engineered components often filled with rubber or hydraulic fluid designed to absorb vibration and dampen noise.
Generally, most Honda Accords feature three to four main engine mounts, plus additional transmission mounts. However, this configuration varies significantly between generations (like the 7th, 8th, or 9th gen) and whether you are driving a 4-cylinder or a V6 model.
Think of engine mounts as the cartilage in your car's skeleton. Their primary jobs are:
1.Securing the Engine: Keeping the heavy engine block firmly attached to the frame.
2.Vibration Dampening: Absorbing the natural vibrations of the combustion engine so they don't transfer to the cabin.
3.Alignment: Keeping the engine properly aligned with the transmission and driveshafts to prevent damage to other components.
To give you a clearer picture, let's look at how the Honda Accord engine mounting system is typically set up. While we can't list every single year model variation in one blog, the following breakdowns cover the most common setups you will encounter.
The 4-cylinder Accords, particularly those from the mid-2000s to early 2010s (like the popular 8th generation), usually utilize a setup involving:
★Front Mount: Located near the radiator. This is often an active or hydraulic mount in newer models to counter idle vibration.
★Rear Mount: Located near the firewall. This takes a significant amount of torque stress during acceleration.
★Side Mount (Passenger Side): Connects the engine block to the side frame rail.
★Transmission Mounts: Usually located on the driver's side and sometimes the rear, supporting the transmission.
The V6 engines produce more torque and require a more robust mounting solution. These often include:
★Front Active Control Engine Mount (ACM): A vacuum-controlled hydraulic mount that adjusts stiffness to dampen the V6's variable cylinder management vibrations.
★Rear Active Control Engine Mount: Similar to the front, working in tandem to smooth out the ride.
★Side Engine Mount: A standard rubber/metal mount.
★Transmission Mounts: Multiple mounts to handle the heavier transmission.
When shopping for replacements, it is crucial to match the Part Number (OE Number) to your specific vehicle chassis code.
For example, looking at the 8th Generation Honda Accord (roughly 2008-2012) and similar chassis, common OE numbers for Honda Accord engine mounting include:
★50810-TA0-A11
★50810-TA0-A12
★50810-TA2-H01
These parts are typically rear engine mounts. They are constructed from durable rubber and metal to withstand the heat and stress of the engine bay. If you have a specific chassis code (like the CP2 or CP3), you will want to cross-reference these numbers to ensure a perfect fit.
Here is a quick reference based on common aftermarket replacement parts found for Honda Accords:
Specification | Details |
|---|---|
Part Name | Engine Mounting / Engine Insulator |
Material | Rubber + Metal |
Common OE Numbers | 50810-TA0-A12, 50810-TA0-A11, 50810-TA2-H01 |
Placement | Typically Rear (depending on specific OE match) |
Vehicle Application | Honda Accord (8th Gen and related models) |
Since engine mounts are made of rubber and fluid, they are subject to wear and tear. Over time, the rubber cracks, or the hydraulic fluid leaks out. How do you know if you need to replace your Honda Accord engine mounting hardware? Look out for these symptoms:
This is the most common sign. If your steering wheel shakes excessively while you are idling at a red light, but smooths out when you accelerate, your mounts (specifically the front or rear active mounts) may be failing.
If you hear a loud thud or clunk when you shift from Park to Drive, or Park to Reverse, that is the sound of the engine shifting physically because a mount is broken. You might also hear this when going over bumps.
Pop the hood and have a friend rev the engine slightly (with the parking brake on and the car in neutral). If the engine rocks violently back and forth rather than staying relatively still, a mount is broken.
If you can see the mounts, inspect them for cracks in the rubber or brown fluid leaking down the side of the metal. Fluid leakage indicates a hydraulic mount has failed.
Replacing engine mounts on a Honda Accord can range from a simple DIY job to a complex project requiring an engine hoist, depending on which mount has failed.
While it is not strictly necessary to replace every mount if only one is broken, it is highly recommended. When one mount fails, it puts extra stress on the remaining mounts, causing them to fail sooner. Replacing them as a set restores the factory geometry and vibration dampening.
You have two main choices: OEM (Original Equipment Manufacturer) or Aftermarket.
★OEM: Guaranteed fit and performance, but often more expensive.
★Aftermarket: High-quality aftermarket suppliers like ST Auto Parts offer mounts that meet OEM standard sizes and quality at a more accessible price point. Look for mounts that offer a warranty (typically 12 months) to ensure peace of mind.
Technically, yes, but it is not recommended for long. A broken mount allows the engine to move excessively, which can damage radiator hoses, wiring harnesses, exhaust pipes, and even the driveshafts.
The cost varies wildly. A single aftermarket mount might cost between $30 and $100. However, labor costs can be significant, especially for the rear mount which is often difficult to access.
Generally, no. While they might look similar, the V6 mounts are often tuned differently to handle the heavier engine weight and different vibration frequencies. Always check the part number.
The Honda Accord is legendary for its reliability and smooth driving dynamics. If that experience has been replaced by rattling and clunking, don't ignore it. Identifying the correct Honda Accord engine mounting configuration is the first step toward a fix.
Whether you need a specific part like the 50810-TA0-A12 or a full kit, ensuring your engine is securely mounted will prolong the life of your vehicle and make your daily commute enjoyable again.
