1998 Daihatsu Terios Engine Mount — What It Does and When To Replace It

Based on technical sources, an engine mount is absolutely fitted to the 1998 Daihatsu Terios (J100 series). The Daihatsu workshop manual for the J100 platform details “engine mounting insulators” and procedures for removal/refit. The Daihatsu Electronic Parts Catalogue also lists left- and right-hand engine mounting insulators and a transmission mount for the same vehicle. Aftermarket catalogues from well-known suppliers (including Mackay Rubber, Febest and Westar) carry dedicated Terios engine mounts and torque rod bushes for 1997–2006 models. So, the engine mount is relevant and used on the 1998 Daihatsu Terios.

On the Terios, the engine mount’s main job is to hold the engine securely while soaking up vibration and torque reaction, keeping things smooth in the cabin and protecting the driveline from harsh shocks. Good mounts also help maintain proper alignment of the exhaust, hoses and shafts, which matters on a compact 4WD that sees mixed city and gravel-road duty. The Terios typically uses a pair of engine insulators and a transmission mount, with some variants adding a torque rod to further control fore–aft movement.

Owners should keep an eye on mounts as the kilometres rack up, especially if the vehicle tows or does corrugated tracks. Typical red flags are:

• Rough vibration at idle or at traffic lights
• Clunks or a thud on take-off, shifting, or over bumps
• Excess engine movement under the bonnet, shifter or exhaust contact
• Visible cracking, collapsed rubber, or leaked fluid from a hydraulic mount

Inspection is a sensible part of a major service—think every 80–100,000 km or when chasing driveline noises. Check fasteners for correct torque, look for perished rubber, and make sure the torque rod bushings (if fitted) aren’t flogged out. When replacement’s due, support the engine from underneath with a jack and a sturdy timber block—never lift by the sump—and change one mount at a time. Using OEM or quality aftermarket mounts is worth it, cheap, overly soft rubbers can cause driveline misalignment or early failure. It’s smart to replace mounts in pairs where practical and to re-check exhaust and radiator hose clearances afterwards. A final road test to confirm smooth idle and clean take-up seals the job.

Popular questions about 1998 Daihatsu Terios engine mounts

How many engine mounts does a 1998 Terios have?
Most 1998 Terios models run two engine mounts (left and right) plus a transmission mount. Some trims include a torque rod to better control fore–aft movement. The exact count can vary by market and drivetrain, so a quick visual under the bonnet and at the crossmember will confirm what’s fitted.

What are the common symptoms of a bad Terios engine mount?
Expect more vibration at idle, a sharp clunk on take-off or gear changes, and noticeable engine rock. You might also see collapsed rubber, torn bonding, or a hydraulic mount that’s leaked. Excess movement can make the exhaust tap the body or change how the gear lever feels.

Is it safe to drive with a failed engine mount?
Short-term, gentle driving might be possible, but it’s not ideal. A failed mount can stress the exhaust, hoses and shafts, and can cause harsh knocks that lead to wider damage. For a small 4WD like the Terios—often used on rough roads—sorting the mount sooner rather than later is the safer bet.
