What it costs, why it matters and when to book a mechanic

What are engine mounts and what do they do?

Engine mounts are components that secure the engine and, in most cases, the transmission to your vehicle's chassis. They are typically made of a combination of metal and rubber or hydraulic fluid, which cushions and absorbs engine vibrations.

The key functions of engine mounts include:

• Stabilising the engine – They keep the engine securely in place, even when the vehicle is accelerating, decelerating, or driving over bumps.

• Absorbing vibrations – The rubber or hydraulic material dampens vibrations from the engine, preventing them from being transferred to the vehicle's cabin.

• Protecting surrounding components – By holding the engine steady, they reduce stress on other engine bay components such as exhaust pipes, hoses, and wiring.

How many engine mounts does a vehicle have?

Most passenger vehicles typically have three to four engine mounts, though the number can vary depending on the make, model, and engine configuration. For example:

• Front-wheel drive cars may have three mounts: two for the engine and one for the transmission.

• Rear-wheel drive vehicles often have four mounts: three for the engine and one for the transmission.

• All-wheel drive and performance vehicles may have additional mounts for extra support due to more complex powertrains.

Each mount plays a specific role, and if one fails, it can place added strain on the others, potentially leading to multiple replacements.

How much to replace engine mounts?

On average, Australian drivers can expect to pay between $445 and $827 for engine mount replacement. This price includes parts and labour but can fluctuate based on:

• Make and model of the vehicle – Luxury or performance vehicles often require more expensive or specialised parts.

• Type and number of mounts – Replacing more than one mount increases cost, and hydraulic or performance mounts are pricier than standard rubber ones.

• Labour intensity – Some mounts are more difficult to access and require additional labour time.

• Location and workshop rates – Urban centres may have higher labour charges than regional areas.

Signs you need engine mount replacement

Watch for the following symptoms that may indicate a failing engine mount:

• Noticeable engine vibrations inside the cabin

• Clunking, banging, or knocking noises during acceleration or deceleration

• Visible movement or tilting of the engine under the bonnet

• Unusual engine noise or misalignment

If you experience any of these issues, it’s important to have your vehicle checked by a qualified mechanic. Driving with worn or damaged mounts can lead to further complications and costly repairs.

Are engine mounts easy or hard to replace?

Engine mount replacement is not a DIY-friendly repair. While some mounts may appear accessible, the job often involves:

• Lifting or supporting the engine safely

• Navigating tight spaces with specialised tools

• Aligning the engine and mount precisely

• Adhering to vehicle-specific torque specifications

Incorrect installation can cause significant issues, including increased vibrations, drivetrain damage, and compromised vehicle safety.

For this reason, engine mount replacement should be performed by a licensed professional with the right experience and equipment.

Are engine mounts expensive to replace?

While the cost of engine mount replacement varies, what truly affects long-term value is the quality of the parts used.

Premium engine mounts are designed to handle heat, vibration, and constant movement more effectively than budget options.They also tend to last longer and perform better, helping to maintain your vehicle’s comfort and reducing the risk of repeat repairs.

Investing in high-quality mounts can save you money over time by improving durability, reducing vibration, and protecting other vehicle components from strain.

How are engine mounts replaced?

Engine mount replacement is a technical procedure that should only be carried out by qualified mechanics. The process usually involves:

• Lifting or stabilising the engine safely

• Removing components for access

• Unbolting and replacing the mount

• Re-torquing to manufacturer specifications

• Rechecking alignment and fitting

Attempting this without professional knowledge or tools is not recommended.

Why timely replacement matters

Neglecting engine mount issues can lead to:

• Increased engine and cabin vibrations

• Potential damage to nearby components

• Compromised handling and performance

Replacing engine mounts when needed ensures a smoother, safer ride and protects other critical components from undue stress.
