I'm fairly new to the montero/4x4 world myself. So far I've done all my own work with a big thanks to this forum, 4x4wire, and the montero Facebook group. I've only owned mine for about 6 months and about half of that has been spent slowly catching up on maintenance (t belt, water pump, oil seals, valve cover seals, valve stem seals, hydraulic lifters, took radiator out and to a local shop here in dickson to be rodded and pressure tested, had to have the alternator taken to a local shop to find out all the internals were loose lol, then some fun things like upgrading all dash lights to LED installing some new LED reverse lights). If you have a Facebook look for the group Mitsubishi Montero USA and send a request and Frank will let you in. It's a very helpful community and you can get answers almost instantly there, where it could take almost a day here since people her usually log in once a day.
