Parts for your 2002 Daihatsu Terios-Engine mount

2002 Daihatsu Terios engine-mount — what it does and when to replace it

Engine mounts are definitely used on the 2002 Daihatsu Terios. This is confirmed by the Daihatsu Terios J100/J102 Series Workshop Manual (Engine Mechanical – Engine Mounting section) and the Daihatsu Electronic Parts Catalogue (EPC) for the J102G, which list right- and left-hand engine mounting insulators and a torque mount. The Toyota EPC for the closely related Toyota Cami (J102E) shows the same arrangement. So yes — engine mounts are relevant to this model.

On a 2002 Terios, the engine mounts secure the engine to the chassis while isolating vibration so the cabin stays smooth and quiet. They also control engine movement under load, keeping driveline geometry tidy and protecting hoses, wiring and exhaust components from stress.

Over time, rubber in the mounts hardens, cracks or collapses. Drivers might notice more vibration at idle, a thump when shifting from Park to Drive, clunks on acceleration or lift-off, or extra movement of the engine when the bonnet’s up. Leaving worn mounts in place can hasten wear on exhaust flex joints, CVs and even cause shifter misalignment.

As part of routine servicing on a Terios, it’s smart to visually check the mounts every 10,000–15,000 km or annually. Look for split rubber, excessive sag, shiny witness marks from metal-to-metal contact, or deteriorated torque-rod bushes. Oil contamination from engine or power-steering leaks can accelerate mount failure, so fix leaks promptly.

• Replacement tips for a Terios:
  • Support the engine safely with a jack and wood block under the sump lip, don’t crush the sump.
  • Replace one mount at a time to keep alignment simple.
  • Loosen all related fasteners before removing any one bolt fully, then snug everything up and final-torque with the engine sitting at normal ride height.
  • Choose quality OEM or reputable aftermarket mounts, cheap units often transmit more vibration.
  • If one mount has collapsed, check the torque rod and the opposite-side mount — they tend to fail in pairs.

Most owners find that fresh mounts make the Terios feel tighter and quieter, especially at idle with the A/C on. It’s a relatively straightforward job for a competent DIYer, but a workshop with a hoist will make it quicker and ensure torque specs are bang on.

Popular questions about 2002 Daihatsu Terios engine-mounts

How many engine mounts does a 2002 Terios have?
Most 2002 Terios (J102) use a right-hand engine mount, a left-hand transmission/gearbox mount, and a front torque mount/rod. That gives three main mounting points that manage weight support and torque control.

What are the common signs the mounts need replacing?
Tell-tales include increased vibration at idle, a clunk when selecting Drive or Reverse, knocking on take-off or over bumps, and visible sag or cracked rubber on the mounts. Excess engine rock with the bonnet open while blipping the throttle is another giveaway.

Do engine mounts affect other components if left worn?
Yes. Excess movement can stress the exhaust flex, stretch hoses and wiring, and accelerate wear in driveline components. It can also make the cabin feel rough and noisy, which many owners mistake for an engine or gearbox issue.
