There's a couple ways. You can remove the a/c box on the firewall, you can remove the engine which is what i do.............and there's a way to do it without removing either but i've never done it. Apparently you slide the back bolts up until they're clear of the threads in the block and put a zip tie around the bolt to hold it up. Ive been told that you can rock the head off the dowels and move it towards the center on the engine...then go up and out. Don't quote me on that but I think that's how I read it. Then to put it back, you just reverse the whole operation. Sounds like it sucks. I found it easier to just take the engine out and do the work on the ground right in front of me, but like anything else...once you do it a few times one way, it's easier to stick with that. The first time is always the hardest. You'll get it though, just keep posting if you've got questions or pm me.
