Parts for your 2006 Toyota Kluger-Engine mount

2006 Toyota Kluger engine mounts: what they do and when to replace them

Yes, the 2006 Toyota Kluger absolutely uses engine mounts. Technical sources back this up: the Toyota Technical Information System (TIS) Repair Manual for Kluger/Highlander ACU2#/MCU2# (2001–2007) includes a dedicated “Engine Mounting” section covering removal and installation of the right-hand, left-hand, front and rear (torque) mounts. The Toyota Electronic Parts Catalog (EPC) likewise lists these as engine mounting insulator sub-assemblies for 2006 Kluger models (e.g., MCU25/MCU28). That’s the factory documentation speaking.

On this Kluger, the engine mounts secure the transversely mounted engine and transaxle to the subframe while soaking up vibration and limiting twist under acceleration and braking. Most Aussie/NZ-delivered 2006 Klugers run the 3.3L V6 (MCU25/MCU28), and they use four mounts: right-hand (engine side), left-hand (transmission side), plus front and rear roll stoppers. Good mounts keep the cabin quiet, protect CV joints and exhaust flex sections, and help the shifter feel crisp.

Mounts are wear items, especially the hydraulic types. Heat, age and oil contamination can soften or crack the rubber, or leak the fluid. It’s smart to have them checked during routine servicing—every 40,000–60,000 kilometres is a fair rhythm, or sooner if you’ve noticed new vibrations.

• Typical symptoms: extra vibration at idle (especially in Drive with A/C on), a thud on take-off or when shifting, visible engine movement under the bonnet when blipping the throttle, or a buzzing through the steering wheel.
• What to inspect: split rubber, collapsed mount height, shiny witness marks from contact, and any oil soaking from engine or transmission leaks.

Replacement is straightforward for a workshop but does require safely supporting the engine/gearbox. Expect roughly 1.0–1.5 hours for a side mount and up to 2–3 hours for the rear mount (AWD can take longer due to subframe clearance). Always torque fasteners to the Toyota spec from the TIS manual, settle the powertrain at normal ride height before final tightening, and avoid jacking under the sump. Many techs replace mounts in pairs to keep NVH balanced. Genuine or reputable OE-equivalent hydraulic mounts are worth it for smoothness and longevity.

After new mounts, a brief idle relearn may help on some vehicles, and it’s wise to recheck fastener torque at the next service. Treat mounts kindly by fixing fluid leaks early—they’re the number-one killer of rubber and hydraulic insulators.

How many engine mounts are on a 2006 Toyota Kluger?

Typically four: right-hand (engine side), left-hand (transmission side), plus front and rear torque/roll mounts. AWD and 2WD both use four, though part numbers can differ. The Toyota EPC and TIS list all four for ACU2#/MCU2# Kluger.

What are the common signs a Kluger’s engine mount is failing?

Shaking at idle in Drive, a thunk on take-off or when shifting, more engine movement than usual under the bonnet, and a droning vibration with the A/C on are all tell-tales. Visible cracks, leaking hydraulic fluid from a mount, or a noticeably lowered engine angle also point to a worn mount.

How often should engine mounts be replaced on a 2006 Kluger?

There’s no fixed interval—condition-based replacement is best. Have them inspected every 40,000–60,000 km. In typical Aussie and Kiwi use, mounts often last 120,000–200,000 km, but heat, towing and fluid leaks can shorten that. Replace when symptoms appear or if damage is found during servicing.
