How to Replace the Engine Mounts on a Mercedes-Benz GLK?

First, remove the heat shield, which requires lifting the engine. Be careful to disconnect the sensor wires and brake fluid lines to avoid pulling them. Remove the alternator and the half-shafts on both sides. Remove the mounting bolts for the engine mounts from both the left and right sides. Use a 13mm wrench. Lower the entire engine and then use a crane to lift it. Avoid overextending the wiring harness and coolant hoses. Once the engine mounts on both sides are detached, they can be removed. Install the new engine mounts.
I've replaced the engine mounts on my Mercedes GLK several times myself, and it's quite an interesting job but requires a full set of tools. The first step is to park on level ground, engage the handbrake, and let the engine cool for half an hour. Then use a jack with a capacity of over three tons to lift the front of the car, making sure the support stands are stable, and remove the front wheels to create more space. Next, crawl under the car and locate the engine mount position at the support points; there are two nuts securing it at the lower side of the engine. Slowly loosen them with an E18 socket wrench, being careful not to apply too much force and break the bolts. If the old mount is aged or deformed, pry it out, clean the mounting surface, and ensure the new mount is aligned with the holes before installation. When tightening the nuts, use a torque wrench to reach 90 Nm to avoid over-tightening and causing damage. After completing the job, lower the car and test drive to see if the engine vibration has reduced. Doing it yourself can save hundreds in labor costs, but if you're inexperienced, it's best to practice on a scrap car first. The whole process takes at least two hours, so take your time and don't rush.
When I first started learning car repairs, even changing engine mounts felt daunting. Now, let me share some tips for beginners. The engine mount on a Mercedes-Benz GLK is a rubber block fixed beneath the engine, which can cause vibrations or strange noises when worn out over time. Replacing it isn’t too complicated: first, turn off the engine and wait about ten minutes for it to cool down, then safely jack up the front of the car—make sure the support stands are properly placed. Next, crawl under to locate the engine mount, remove the nuts to take out the old mount, align the new one into the slot, and tighten it back up. All you need are basic tools like a wrench and a jack, which you can rent online if necessary. If you can’t see the position clearly, take photos with your phone or follow step-by-step videos from a car repair app. It’s also a good idea to have a friend assist, especially when moving the engine to prevent parts from slipping. A new mount costs around 300-400 RMB, and tools can be rented for just a few dozen RMB. Doing it yourself saves the 200-300 RMB labor fee you’d pay at a shop—simple, safe, and cost-effective.
