Parts for your 2018 Toyota Avensis-Engine mount

2018 Toyota Avensis engine mount — purpose, servicing and replacement

Yes, the 2018 Toyota Avensis (T27 series) uses engine mounts. Technical sources that document this include Toyota’s Avensis (T27) Repair Manual and the Toyota Electronic Parts Catalogue, which list “engine mounting insulator assemblies” for the right-hand (engine side), left-hand (transmission side) and a front torque rod. Independent data providers and workshop references used across Australia and New Zealand (e.g., Autodata/Haynes) also specify engine mount inspection and replacement procedures for 2015–2018 Avensis petrol and diesel variants.

On this Avensis, the engine mounts do the heavy lifting quietly. They secure the engine and gearbox to the body, soak up vibration at idle and on the move, and keep everything aligned so the driveshafts, exhaust and ancillaries aren’t copping extra stress. Under acceleration and braking, the mounts check engine rock, which helps drivability and protects hoses, wiring and the exhaust flex. Many variants use a hydraulic (fluid-filled) mount on the engine side to improve comfort, and a torque rod up front to control twist.

They’re not a routine “replace by date” service item, but they should be checked at every service interval. In Aussie and Kiwi conditions — heat, stop–start, rougher roads — rubber can harden or crack and hydraulic mounts can leak. Typical inspection includes looking for perished rubber, collapsed height, split housings or fluid weep, then confirming excessive engine movement with a brief power-brake test under the bonnet (with proper safety). Most owners will notice tell-tales first: extra vibration at idle (especially with the A/C on), a thump on take-off or gear changes, or a buzz through the cabin at certain revs.

• Common signs of a worn mount
  • Harsh vibration at idle or when selecting Drive/First
  • Clunk on throttle on/off or during shifts
  • Visible sagging, cracking or fluid leakage on the mount
• Service tips for replacement
  • Support the engine safely, torque fasteners at normal ride height
  • Replace any torn torque rod bushes, consider doing mounts as a set if high kilometres
  • Use OE or high-quality aftermarket parts to keep NVH in check
  • Afterwards, recheck exhaust flex, hoses and wiring for strain

How long do they last? It varies with driving and load, but many shops see the first mount complaints somewhere after 100,000–160,000 kilometres. If the Avensis is shuddery, noisy or clunky and other causes are ruled out, fresh mounts can bring it back to the smooth, quiet feel it left the factory with.

Popular questions about 2018 Toyota Avensis engine mounts

How long do engine mounts last on a 2018 Avensis?
Most last well past 100,000 kilometres, and many see 150,000–200,000 kilometres before noticeable symptoms. Heat, towing, city commutes and rough roads can shorten that. Regular inspection at each service helps spot small issues before they turn into big vibrations.

Can you drive with a worn engine mount?
If it’s only slightly tired, the car will often still be driveable, but comfort and refinement suffer. If a mount is torn or collapsed, continued driving can stress the exhaust, hoses and driveshafts, and you may get harsh thumps on take-off. It’s best to book it in promptly to prevent follow-on damage.

Do petrol and diesel Avensis models use different mounts?
Yes, mount designs and stiffness vary between engines and transmissions. The Toyota EPC lists different part numbers across 1.6/1.8 petrol and 1.6/2.0 diesel variants, and sometimes between manual and automatic/Multidrive S. Always match the mount to the exact VIN and powertrain.
