Step-by-step guide to replacing the passenger side engine mount on a 2018-2021 Honda Accord with the Precision Works kit, including torque specs and common mistakes.

Quick Answer

Replace the passenger side engine mount on your 2018-2021 Accord with the Precision Works Engine Mount Kit by supporting the engine, removing the old mount, and torquing the new one to spec. This DIY takes about two hours and restores engine stability.

Why Replace the Passenger Side Mount?

The passenger side mount is a common failure point on the 2018-2021 Accord, often showing symptoms like excessive vibration at idle, a clunking noise when shifting, or visible cracks in the rubber bushing. Replacing it early prevents stress on the other mounts and keeps the drivetrain aligned.

While you can replace just the passenger side mount, consider inspecting the other mounts at the same time. If they show similar wear, replacing them together saves labor later, though it increases the upfront cost.

What You'll Need

Gather a floor jack, a block of wood, a socket set with extensions, a torque wrench, and a breaker bar. You'll also need the new Precision Works mount and, ideally, new bolts if the originals are corroded.

The Precision Works Engine Mount Kit is engineered to minimize excessive engine movement, providing enhanced stability and improved performance. It's a direct-fit upgrade for the 2018-2021 Accord, so no modifications are required.

Installation Steps

Support the Engine: Place a floor jack with a block of wood under the oil pan (or a designated lift point) and raise it just enough to take the weight off the mount. Do not lift the car off the ground. The engine must be supported before you remove any mount bolts.
Remove the Old Mount: Use a socket and breaker bar to remove the bolts securing the mount to the chassis and the engine bracket. If the mount is seized, apply penetrating oil and let it sit for 10 minutes before trying again. Don't force a stubborn bolt—use penetrating oil to avoid stripping.
Clean the Mounting Surfaces: Wipe the engine bracket and chassis mounting points with a clean rag to remove dirt and oil. This ensures the new mount sits flat and prevents premature wear. A clean surface helps the mount seat correctly and avoids alignment issues.
Install the New Mount: Position the Precision Works mount in place and hand-thread the bolts. Tighten them in a crisscross pattern to avoid binding, then torque to spec: 49 ft-lbs for the chassis bolts and 32 ft-lbs for the engine bracket bolts. Always use a torque wrench—over-tightening can damage the mount's rubber bushing.
Lower the Engine and Test: Slowly lower the jack, then start the engine and let it idle. Check for excessive vibration and listen for any clunking. If the engine still moves excessively, re-check the torque on all bolts. A smooth idle and no movement when revving indicates a successful install.
