This is a great thread. I have a 93 Suburban with leaking coolant that I think is coming out of the intake manifold just above the right water pump attachment. Will these directions work for a 93 as well? From the pics, I saw one difference was the AC compressor. I'm wondering what else is different as I may be so bold/foolish to take this on myself since it purports to be such an expensive repair shop job. Thanks.
