Get Mazda Demio DE Engine Mounting Assy D652-39-060 in Kenya
The engine mounting assembly, also known as the engine mount, is a critical component of a vehicle’s drivetrain. Whether you drive a Toyota Prado 120/150, Nissan Note, Wingroad, Tiida, or any other car, the engine mount plays a crucial role in stabilizing the engine, absorbing vibrations, and maintaining alignment.
A worn-out or broken engine mount can lead to excessive engine movement, vibrations, misalignment, and even damage to other components. In this guide, we will cover the function of engine mounts, types, common failure symptoms, maintenance tips, and how to replace them.
What Is an Engine Mounting Assembly? 🤔
The engine mount is a rubber and metal bracket that secures the engine to the vehicle’s chassis. It absorbs shocks, vibrations, and movement generated by the engine and prevents excessive shifting when the car is in motion.
Main Functions of an Engine Mount:
🔹 Secures the Engine – Holds the engine in place and prevents movement.
🔹 Reduces Vibrations – Absorbs engine vibrations for a smooth ride.
🔹 Prevents Engine Damage – Minimizes stress on engine components.
🔹 Supports Transmission Alignment – Ensures proper drivetrain function.
🔹 Enhances Driving Comfort – Reduces cabin noise and harshness.
Without a properly functioning engine mount, your vehicle may experience excessive engine movement, vibrations, and potential drivetrain misalignment.
How Does an Engine Mount Work? ⚙️
The engine mount assembly consists of a rubber or polyurethane cushion encased in metal. Some modern mounts are hydraulic or electronic for better vibration damping.
Working Principle:
1️⃣ The engine generates vibrations and movement during operation.
2️⃣ The engine mount absorbs these vibrations using rubber or fluid-filled cushions.
3️⃣ It prevents excessive movement of the engine when accelerating or braking.
4️⃣ Maintains alignment between the engine and transmission.
5️⃣ Ensures the vehicle operates smoothly without excessive noise or shaking.
If an engine mount fails, the engine can move excessively, causing vibrations, clunking sounds, and alignment issues.
Why Is the Engine Mount Important? 🚘
Your vehicle’s engine mount is essential for:
✔️ Engine Stability – Keeps the engine secure in place.
✔️ Vibration Control – Reduces cabin noise and discomfort.
✔️ Transmission & Drivetrain Health – Prevents misalignment.
✔️ Extended Engine Life – Reduces unnecessary stress on components.
✔️ Smooth Driving Experience – Eliminates shaking and rattling.
A damaged or worn-out engine mount can lead to significant engine misalignment, affecting performance and safety.
Signs of a Failing Engine Mount 🚨
Engine mounts typically last between 80,000 – 150,000 km, but they can fail earlier due to stress, age, and harsh driving conditions. Here are the most common warning signs:
🛑 Excessive Engine Vibration – The vehicle shakes more than usual.
🔊 Loud Clunking or Banging Noises – When accelerating or shifting gears.
⚙️ Engine Movement – The engine shifts more than normal under the hood.
🚗 Misalignment of Transmission & Drivetrain – Leads to poor power transfer.
💨 Increased Cabin Noise – More engine noise inside the car.
🔴 Visible Cracks or Wear on the Mount – Inspect for physical damage.
Ignoring these symptoms can lead to serious drivetrain damage and costly repairs.
Common Causes of Engine Mount Failure ❌
Several factors can cause engine mounts to wear out or break:
🔹 Age & Mileage – Rubber degrades over time, losing elasticity.
🔹 Excessive Engine Vibrations – Poor balance or misalignment increases stress.
🔹 Rough Driving & Potholes – Impacts weaken the mount over time.
🔹 Oil & Coolant Leaks – Fluids degrade rubber components.
🔹 Incorrect Installation – Poor fitting causes premature wear.
If you notice signs of engine mount failure, it’s crucial to replace it immediately.
Types of Engine Mounts 🛠️
There are different types of engine mounts, each designed for specific vehicles and performance needs:
1️⃣ Rubber Engine Mounts
✔️ Common in most vehicles
✔️ Affordable and effective at reducing vibrations
✔️ Can wear out over time due to rubber degradation
2️⃣ Hydraulic Engine Mounts
✔️ Filled with liquid for better vibration absorption
✔️ More effective in reducing noise & harshness
✔️ More expensive than standard rubber mounts
3️⃣ Electronic/Active Engine Mounts
✔️ Used in high-end and luxury vehicles
✔️ Automatically adjusts damping based on engine load
✔️ More complex and costly
For Toyota Prado 120/150, Nissan Note, Wingroad, and Tiida, hydraulic or rubber engine mounts are commonly used.
How to Replace an Engine Mount – Step-by-Step Guide 🔧
Replacing an engine mount requires mechanical knowledge and proper tools.
Tools & Materials Needed:
✔️ New engine mount assembly (OEM or aftermarket)
✔️ Jack & jack stands
✔️ Wrenches & sockets
✔️ Torque wrench
✔️ Engine support (jack or hoist)
Replacement Process:
1️⃣ Lift the Vehicle – Secure it with jack stands.
2️⃣ Support the Engine – Use a jack to hold the engine in place.
3️⃣ Locate the Engine Mounts – Usually found on both sides of the engine.
4️⃣ Unbolt & Remove the Old Mount – Carefully detach it.
5️⃣ Install the New Mount – Align it properly before securing.
6️⃣ Tighten Bolts to Spec – Use a torque wrench.
7️⃣ Lower the Engine & Test Drive – Ensure proper fitment.
💡 Tip: If replacing one engine mount, check the others for wear as well.
OEM vs Aftermarket Engine Mounts 🏁
When choosing an engine mount replacement, you have two options:
🔹 OEM (Original Equipment Manufacturer):
✔️ Designed for a perfect fit
✔️ High-quality materials and durability
✔️ More expensive but long-lasting
🔹 Aftermarket Engine Mounts:
✔️ Available from various brands
✔️ Some offer performance improvements
✔️ Quality varies – Choose trusted brands
For Toyota Prado 120/150, Nissan Note, Wingroad, and Tiida, OEM engine mounts provide the best fit and durability.
Maintenance Tips for Long-Lasting Engine Mounts 🏎️
To extend the lifespan of your engine mounts, follow these tips:
✅ Inspect Engine Mounts Every 50,000 km – Look for cracks or leaks.
✅ Fix Oil & Coolant Leaks – Prevent rubber degradation.
✅ Avoid Harsh Acceleration & Braking – Reduces stress on mounts.
✅ Drive Smoothly on Rough Roads – Prevents excessive impact damage.
✅ Replace Worn Mounts Immediately – To avoid damage to other components.
Proper maintenance ensures a smooth and vibration-free ride.
Final Thoughts 💭
The engine mounting assembly is a vital component that secures the engine, reduces vibrations, and ensures smooth operation. Keeping it in good condition prevents misalignment, excessive noise, and drivetrain issues.
