I recently bought a 2007 quest 3.5SE with a bad knock in the engine. I bought it from a friend of mine along with a new engine to put into it. Im pretty sure it will have to come out the bottom with the subframe, trans etc. Does anyone have step-by-step instructions to do this, I searched and couldn't find anything. Any help would be greatly appreciated, thanks!

Hey, welcome to NICO Club!

We have the factory service manual for many vehicles here. That will have instruction for the engine removal and installation. They're broken up into chapters. The FWD chapter is the foreward and will have a table of contents. All of them are PDF documents and you can download them to your device so you can use them while working on the van without needing internet connection.
