How to Replace Front Engine Mount 02-06 Nissan Altima

Difficulty: Intermediate · About 45 min · Nissan Altima

Replace a worn front engine mount while safely supporting the powertrain and keeping the mount bolts aligned during installation.

Steps

1. Loosen the mount hardware

   Apply penetrant if the fasteners are rusty, then loosen the upper and lower mount fasteners while leaving them threaded in place.

2. Support the engine and remove the mount

   Place a floor jack with a wood pad under a suitable engine support point and raise it only enough to unload the mount. Remove the fasteners and guide the old mount out.

3. Position and secure the replacement

   Set the new mount in place and start every fastener by hand. Adjust the engine height slightly until the holes line up without forcing the bolts.

4. Tighten and verify

   Tighten the mount hardware to the correct specification for the vehicle, then lower the jack gradually and confirm the mount remains seated.

Check your vehicle’s repair manual for exact specifications and fit.
