Re: Replacing the coolant crossover pipe
According to the 3.5L 2001 Aurora procedure both the EGR inlet and outlet pipes (Both of the flexible lines that attach to the coolant crossover) have a crush connection on the end that attaches to the Water Crossover. Inorder to reuse the hoses the procedure recommends not to remove the connections to the water crossover. Remove the other ends. This of course doesn't make using the crow bar trick any easier with this stuff attached.
It's funny that the Intrigue shows 6.5 hours of labor for this job, but with no procedure. But the Aurora mentions the procedure of removing the right manifold exhaust manifold. But both the Intrigue and Aurora procedures for the right manifold require near engine removal! So this will be a great trick and it sounds like it might work!
