1998 Toyota Altezza Engine Mounts — What They Do and When to Replace

Technical sources confirm that the 1998 Toyota Altezza (XE10 platform — GXE10 1G‑FE and SXE10 3S‑GE) uses engine mounts. The Toyota Electronic Parts Catalog lists “Insulator, Engine Mounting (RH/LH)” and associated brackets for XE10, and the Toyota/Lexus Repair Manual for the IS200/Altezza details removal, inspection and installation procedures. That makes the engine mount a relevant, fitted component on this vehicle.

The engine mount on a ’98 Altezza plays a bigger role than most drivers realise. Bolted between the engine and the front subframe, the rubber—often hydraulic—insulators hold the 1G‑FE or 3S‑GE steady under the bonnet while soaking up vibration so the cabin stays calm. They also control drivetrain movement during take‑off, shifts and hard cornering, keeping exhaust, hoses and shifter linkage from copping a hard time. On the road, that translates to smoother idle, cleaner gear changes and fewer bangs or clunks when loading and unloading the drivetrain.

Like any rubber part, mounts age. Heat, oil mist and years of load cycles can split the rubber or bleed the fluid from hydraulic types. Common tell‑tales on an Altezza include a shaky idle that’s worse in Drive, a thump on take‑off, excessive engine rock when blipping the throttle, or a noticeably lower engine sitting height on one side. Left too long, failed mounts can stress exhaust joints and ancillaries.

As part of regular servicing, it’s smart to inspect the engine mounts every 40,000–60,000 kilometres or at major services. A quick torch check for cracks, collapsed rubber or fluid seep, plus a gentle pry‑bar test for excessive movement, goes a long way. If one side is cooked, replacing both left and right mounts as a pair keeps balance and NVH in check. Most techs support the sump with a block of timber and a jack, swap mounts one side at a time, and torque fasteners with the engine at normal ride height.

• Use quality OEM or reputable aftermarket hydraulic mounts for road cars, solid or race mounts will bump up NVH.
• After replacement, recheck exhaust clearance and shifter feel, and re‑torque mount fasteners after a few hundred kilometres.
• Typical labour is about 1–1.5 hours per side, depending on tools and access.

For the XE10 platform, the Toyota EPC and workshop manual procedures back up these practices, covering mount identification, torque specs and inspection criteria used by dealers and specialists alike.

Popular questions about 1998 Toyota Altezza engine mounts

How many engine mounts does a 1998 Altezza have?

The XE10 typically runs two main engine mounts (left and right) plus a transmission mount at the rear of the gearbox. All three work together to control drivetrain movement and cabin vibration.

What are the signs my Altezza’s engine mounts need replacing?

Look for harsh vibration at idle, a clunk on take‑off or when shifting, visible cracks or oil weep from the mount, or the engine sitting low on one side. Excessive engine rock when revved in neutral is another giveaway.

Should they be replaced in pairs, and is there a set interval?

There’s no strict kilometre interval, condition rules. Many last well over 150,000 km, but age and heat matter. If one side fails, doing both sides together restores balance and keeps vibration down.
