1. Before installing the kit, I gave the exhaust manifold connection surface a bit of a wire brush cleaning. Other kits advise you to use a ultra-high temp copper-based gasket liquid between the block-off disk and the exhaust manifold; the EGR tube doesn't have this material so I didn't use any either.
2. This step is possibly the most difficult of the entire process; I have always struggled with these rigid clamp/bolt setups. You have to put the block-off disk from the kit into the clamp and put the clamp over the exhaust manifold tube at the same time. Orient the disk in the clamp so that from outside the disk is convex--the folded edge of the disk mates with the tapered edge of the exhaust manifold tube. All of this has to be in place while you get the bolt inserted into the clamp and threaded. I find that if before I try to insert the bolt I use a pair of slip joint pliers to squeeze the clamp ends together (squeeze the clamp shut) that threading the bolt is much easier.
3. After some very nasty cleaning inside of the EGR/intake maniforld port, I did some mild scraping/cleaning (careful, its aluminum) on the intake manifold port surface to ensure it was flat before installing the gasket and the block-off plate and the two replacement bolts. The replacement bolts must be used because they are shorter than the original EGR bolts. I used anti-seize on these bolts because they are steel and the bolt holes are aluminum.
