I own 3 Monteros. All are running well presently but have over 170,000 miles on them so I'm starting to look around for parts options. I only paid $2,500 for each.

I don't come across full sized Monteros often in my rural western Colorado so I'm looking for options for their motors and transmissions.

I have:
Two each 2001 XLS models with 3.5L, and
One 2003 Limited with 3.8L. All are automatic transmissions.

Does anyone know what other models can be used for major parts such as motor blocks, heads, and transmissions?

Thank you!

 

Not real sure. Maybe these links will guide you. I had tried to broaden my used engine search as well, but in the end decided to rebuild mine. I think some of the Chrysler products used the same engine design for awhile so take these links with a grain of salt.
