A basic toolkit plus engine-support gear will cover most engine-mount replacements: floor jack, jack stands, a socket set, and a torque wrench, along with an engine-support method and some common hand tools. You may also need specialty items if bolts are stubborn or access is tight.
Engine mounts secure the engine to the chassis and dampen vibration. Replacing them typically involves lifting the engine to relieve load, removing fasteners around the mount area, and installing new mounts with the correct torque. Because vehicle designs vary, the exact tools and steps can differ by make and model, but the core tool categories below apply to most front- and rear‑engine layouts. Check your service manual for model-specific instructions and torque specs.
Core tools for a standard engine-mount change
The following core tools cover the bulk of front- or rear-engine mount replacements on common passenger cars. They enable safe lifting, access, and reliable reassembly.
- Floor jack and jack stands
- Wheel chocks
- Socket set (metric sizes common to the vehicle) with ratchet and extensions
- Combination wrenches (metric)
- Breaker bar for stubborn fasteners
- Torque wrench to spec
- Pry bar or flat bar for separating mounts from mounts’ seating points
- Screwdrivers (flathead and Phillips) and small pry tools
- Engine support tool (engine support bar/brace) or an appropriate portable engine hoist/strap
- Penetrating oil for stubborn bolts
- Rubber mallet or dead-blow hammer for gentle persuasion
- Magnetic parts tray to keep bolts organized
- Safety gear: gloves and safety glasses
With these core tools, you can perform most stepwise removal and installation tasks for standard engine mounts on a wide range of vehicles. Some models may require additional, model-specific fasteners or brackets.
Support, safety, and specialty items
For tight spaces, hard-to-reach fasteners, and ensuring the engine remains securely supported during the job, consider these specialty tools and accessories.
- Impact wrench or impact driver (air or cordless) for hard-to-break bolts
- Long extensions, flexible joints, and universal joints to reach recessed bolts
- Torx, Allen (hex), or other bit sets as required by your vehicle’s bolts
- Locking pliers (Vise-Grip) and magnetic pickup tool to secure or retrieve bolts
- Engine support strap/chain and a compatible hoist or overhead support method
- Torque-angle gauge or an updated torque-spec tool if the manufacturer specifies angle tightening
- Threadlocker (blue) for reinstalling bolts and anti-seize lubricant for corrosion protection
- Additional penetrating oil and, if needed, a high-temperature grease for mount interfaces
These specialty tools help when bolts are seized, when space is limited, or when precise engine alignment and torque are required for the new mounts to seat properly.
Summary
Changing engine mounts hinges on a solid plan and the right tools: a basic mechanical toolkit, engine-support gear, and the option for specialty tools if bolts are stubborn or access is limited. Always consult your vehicle’s service manual for model-specific steps, fastener sizes, torque specs, and any special mounting brackets. When in doubt, consider seeking professional help to avoid damage to the engine, transmission, or subframe.
