The 2000 Toyota Sienna minivan uses four main mounts for the engine: The front mount, the right mount, the rear mount and a shock-absorbing mount. In many cases, you should never need to service or replace these engine mounts, but you'll need to replace a mount that has deteriorated or broken. The rear engine mount is a casting bracket that supports the engine's rear insulator and is connected to the chassis.

Step 1

Disconnect the vehicle's negative battery cable.

Step 2

Raise the van's front end with a floor jack and support it on jack stands.

Step 3

Place the floor jack underneath the engine at the oil pan and place a wood block on top of the jack. Raise the jack under the oil pan, making sure the block doesn't touch the drain plug, until the Sienna's weight is off the engine mounts.

Step 4

Unscrew and remove the through bolt that connects the rear engine mount to the chassis bracket using a wrench. Remove the insulator bolts and remove the mount.

Step 5

Position the replacement engine mount on the engine. Apply a thread-locking compound to the insulator bolts' threads and apply them, tightening them securely with the wrench. Apply the through bolt with the same compound.

Step 6

Lower the engine off the floor jack and the vehicle off of the jack stands, then reconnect the car battery.
