1999 Toyota Avensis Engine Mount: Purpose, Fitment, and Servicing Tips

Engine mounts are absolutely fitted to the 1999 Toyota Avensis (T22). Technical sources that confirm this include the Toyota Technical Information System (TIS) Avensis (T22, 1997–2003) Repair Manual sections covering “Engine Mounting/Engine Mounting Insulator,” the Toyota Electronic Parts Catalogue (EPC) diagrams for the Avensis T22 listing right-hand engine mount, left-hand transaxle mount, and front/rear torque mounts, and the Haynes Toyota Avensis (Feb 1998–2003) workshop manual, which details inspection and replacement. So, engine mounts are relevant to this vehicle.

On a ’99 Avensis, the engine mounts do the heavy lifting of holding the transverse engine and gearbox steady while soaking up vibration and controlling engine rock under throttle. Typically there are four mounts: a right-hand engine mount on the timing-belt side, a left-hand gearbox mount, plus front and rear torque mounts (also called roll stoppers). Some are rubber-only, while others can be fluid-filled for better vibration isolation.

When servicing, it’s smart to give the mounts a once-over every 20,000–30,000 kilometres, or any time there’s a rattle or shake. Common signs they’re on the way out include harsh vibration at idle, a thud on take-off or gear changes, excessive engine movement when blipping the throttle in neutral, and visible cracking or collapsing of the rubber. If a hydraulic mount is fitted, fluid stains around the insulator are a giveaway.

Replacement is straight-forward with the right approach:

• Support the engine/gearbox safely from underneath with a jack and a timber block before loosening any mount hardware.
• Loosely fit the new mount, lower the engine to normal ride height, then torque fasteners to factory spec from Toyota TIS.
• If one mount has collapsed, consider replacing the opposite or all mounts, especially on higher-kilometre cars, to keep NVH balanced.
• After fitting, check exhaust flex, hoses, and shifter cables for strain, and road-test for smooth idle and clean take-up.

For the Avensis, quality OEM or reputable aftermarket mounts keep vibration down and driveline alignment sweet. A fresh set can transform cabin comfort, stop that steering-wheel buzz, and protect other components like exhaust joints and CVs from being overworked.

Popular questions about 1999 Toyota Avensis engine mounts

How many engine mounts does a 1999 Avensis have?
Most 1999 Avensis models run four mounts: right-hand engine, left-hand gearbox, plus front and rear torque mounts. Petrol and diesel variants share the same basic layout, though insulator design can differ by engine code.

How long do engine mounts last on a 1999 Avensis?
Anything from 150,000 to 250,000 kilometres is common, but age, heat, and rough roads matter. Fluid-filled mounts may soften or leak earlier. If there’s idle shake, clunks, or visible cracking, it’s time to plan a change.

Can worn engine mounts damage other parts?
They can’t usually break a gearbox outright, but they do increase vibration and engine movement, which can stress the exhaust flex, inner CV joints, and shifter cables. Replacing tired mounts often cures shudder and protects those parts.
