The Nissan Rogue SV, a popular compact SUV, has won the hearts of many drivers for its practicality, comfort, and reliability. Central to its smooth operation is the engine mount system. If you're a Nissan Rogue SV owner, understanding the ins and outs of your vehicle's engine mounts can help you maintain optimal performance and avoid potential issues down the road. This guide will walk you through everything from what engine mounts are and their importance in the Nissan Rogue SV to signs of wear, replacement procedures, and more.
The engine of a Nissan Rogue SV, whether it's the standard 2.5-liter four-cylinder engine found in many models, is a heavy and complex piece of machinery. Engine mounts are designed to bear the weight of the engine, keeping it in the correct position within the engine bay. This proper positioning is essential for the engine to work in harmony with other components such as the transmission, driveshaft, and exhaust system. For example, if the engine is not held in place correctly, it can cause misalignment with the transmission, leading to problems in power transfer and potentially causing damage to both components.
Engines, by their very nature, produce vibrations during operation. These vibrations are a result of the internal combustion process, where pistons move up and down rapidly, and the crankshaft rotates. In the Nissan Rogue SV, engine mounts play a vital role in reducing these vibrations from being transmitted to the rest of the vehicle. The rubber components of the engine mounts are engineered to absorb and dissipate these vibrations. Without effective engine mounts, the vibrations would be felt throughout the car, causing discomfort to the driver and passengers, and potentially leading to premature wear of other vehicle parts due to the continuous shaking.
A Nissan Rogue SV with healthy engine mounts offers a smooth and comfortable ride. The engine mounts' ability to dampen vibrations means that you won't feel excessive shaking or rumbling while driving. This is especially important during idle, when the engine is still running but not under heavy load. A smooth idle is a sign that the engine mounts are doing their job correctly, allowing you to enjoy a quiet and comfortable driving experience, whether you're stuck in traffic or cruising on the highway.
By keeping the engine firmly in place and reducing vibrations, engine mounts in the Nissan Rogue SV protect other critical components. For instance, they prevent the engine from shifting or moving around during acceleration, braking, or cornering. This stability is crucial for the proper functioning of the exhaust system. If the engine were to move excessively, it could cause the exhaust pipes to bend or break, leading to exhaust leaks. Additionally, the transmission benefits from stable engine mounts as it ensures a consistent connection between the engine and the transmission, reducing the stress on transmission components and extending their lifespan.
Properly functioning engine mounts also contribute to the safety of the Nissan Rogue SV. In the event of a collision, the engine mounts are designed to keep the engine in its place within the engine bay. This helps prevent the engine from moving into the passenger compartment, which could cause serious injury to the driver and passengers. Additionally, since engine mounts affect the overall handling and stability of the vehicle, worn-out mounts can lead to unpredictable handling, especially during sudden maneuvers, increasing the risk of accidents.
One of the most noticeable signs of worn engine mounts in a Nissan Rogue SV is an increase in vibration. You may feel a significant shaking in the steering wheel, gearshift, or seat, especially when the engine is idling. This vibration can range from a mild rumbling to a more severe shaking, depending on the extent of the damage to the engine mounts. If you notice that your Rogue SV has become much more vibratory than usual, it's a strong indication that the engine mounts may be worn out and are no longer effectively dampening the engine's vibrations.
Worn engine mounts can also produce unusual noises. You may hear clunking or knocking sounds, especially when you start or stop the engine, shift gears, or accelerate. These noises occur because the engine is moving more freely than it should due to the weakened or damaged mounts. For example, when you shift from park to drive, the engine may shift slightly, causing a clunking noise if the mounts are not holding it firmly in place.
In some cases, you may be able to visually observe the engine moving more than normal. If you open the hood of your Nissan Rogue SV and notice that the engine seems to be sitting at an odd angle or is shifting more than you remember, it could be a sign of damaged engine mounts. This misalignment can also affect the performance of other components connected to the engine, as mentioned earlier.
Some engine mounts in the Nissan Rogue SV are filled with hydraulic fluid to enhance their vibration-dampening capabilities. If you notice a pool of fluid under your vehicle, it could be a sign that one of these hydraulic engine mounts has developed a leak. This fluid is usually a clear or slightly colored liquid, and if left unattended, it can cause the engine mount to fail completely.
◆Socket set: You'll need a variety of socket sizes to remove and install the bolts that hold the engine mounts in place.
◆Jack and jack stands: To safely lift the vehicle and support it while working on the engine mounts.
◆Torque wrench: This is crucial for tightening the bolts to the manufacturer's specified torque settings. Using the wrong torque can lead to the engine mounts not functioning properly or even coming loose.
◆Pry bar: A pry bar can be useful for gently prying the old engine mounts out of place and positioning the new ones.
Engine support bar (optional but recommended): For larger engines, an engine support bar helps lift and stabilize the engine slightly when removing mounts, preventing strain on other components.
◆Safety First: Before starting any work on your vehicle, make sure it is parked on a level surface and the emergency brake is engaged. Disconnect the negative terminal of the battery to prevent any electrical accidents.
◆Lift the Vehicle: Use a jack to carefully lift the Nissan Rogue SV and place jack stands under the vehicle's frame at the recommended lifting points (check your owner’s manual for exact locations—typically near the front wheels and rear of the front subframe). Make sure the vehicle is stable and secure on the jack stands before proceeding.
◆Locate the Engine Mounts: In the Nissan Rogue SV, the engine mounts are typically located at three key points:
◆Front mount: Positioned near the front of the engine, connected to the front subframe.
◆Rear mount: Attached to the rear of the engine block and the vehicle’s chassis.
◆Transmission mount: While not a strict “engine mount,” it works with engine mounts to stabilize the powertrain—located where the transmission connects to the subframe.
Remove any plastic engine covers or heat shields that block access to the mounts (use a socket wrench to remove retaining bolts).
◆Support the Engine: If replacing the front or rear mount, use an engine support bar (secured to the engine bay’s lifting points) or place a jack with a rubber pad under the oil pan to lift the engine slightly (1–2 inches). This relieves pressure on the old mount, making it easier to remove without damaging surrounding parts.
◆Remove the Old Mounts: Use a socket wrench to remove the bolts connecting the old mount to the engine and chassis. For rusted bolts, spray penetrating oil and let it sit for 10–15 minutes to loosen. Once bolts are removed, use a pry bar to gently separate the mount from the engine/chassis—avoid forcing it, as this can bend metal components.
◆Inspect and Clean: Check the engine and chassis mounting points for rust, cracks, or debris. Use a wire brush to clean any rust or dirt, ensuring the new mount sits flush. If mounting points are damaged, consult a mechanic—this may require professional repair.
◆Install the New Mounts: Align the new engine mount with the mounting points (ensure rubber bushings are oriented correctly—match the old mount’s position). Hand-tighten the bolts first to hold the mount in place, then use a torque wrench to tighten them to Nissan’s specified torque (typically 30–45 ft-lbs for Rogue SV—check your service manual for exact values).
◆Reassemble and Test: Remove the engine support/jack, reattach any engine covers or heat shields, and reconnect the battery. Start the engine and let it idle—check for vibrations or unusual noises. Take the vehicle for a short test drive, accelerating and shifting gears to ensure the new mounts perform correctly.
The Nissan Rogue SV has had minor powertrain updates over the years (e.g., 2014–2020 2.5L QR25DE engine, 2021+ 1.5L VC-Turbo engine). Ensure the mount is labeled for your specific model year—using an incompatible mount can cause misalignment and vibration.
OEM (Original Equipment Manufacturer) mounts: Made by Nissan or its authorized suppliers, these match the factory mount’s fit and performance. Ideal for those seeking exact replacement, though they may cost more (typically 80–150 per mount).
Aftermarket mounts: Reputable brands (e.g., Dorman, Beck/Arnley) offer affordable alternatives (40–100 per mount) with similar durability. Look for mounts with high-quality rubber bushings (resistant to heat and oil) and corrosion-resistant metal brackets.
Avoid cheap generic mounts: These often use low-grade rubber that degrades quickly, leading to premature failure and vibration issues.
Rubber mounts: Standard for most Nissan Rogue SV models—offer good vibration dampening and affordability.
Hydraulic mounts: Found in some newer Rogue SV trims—use hydraulic fluid for enhanced vibration control. If your vehicle originally had hydraulic mounts, replace them with the same type (generic rubber mounts won’t match performance).
On average, engine mounts last 60,000–100,000 miles. However, harsh driving (e.g., frequent stop-and-go traffic, off-roading) or exposure to extreme temperatures can shorten their lifespan to 40,000–60,000 miles.
Short-term driving (a few miles to a mechanic) is possible, but long-term use is risky. Worn mounts cause excessive vibration, which can damage the transmission, exhaust system, and electrical components. They also reduce handling safety—avoid driving long distances with damaged mounts.
DIY cost:120–450 (for 3 mounts, plus tools if needed).
Professional cost:300–800 (includes parts and labor—mechanics charge 1–2 hours of labor,100–150 per hour).
Not necessarily—if only one mount is worn (e.g., rear mount), replace that one. However, if the vehicle has over 80,000 miles, it’s often wise to replace all three mounts. This prevents uneven wear on new mounts (a single old mount can cause the new ones to fail faster) and avoids repeated repair visits.
