Andras - thanks for the comments. I have edited post #1 and added your comments about the tight reach tool not being absolutely necessary. In particular, I have since found that if the radiator fan/shroud is removed first, then there is adequate access to the air duct clamp bolts. Though I still think the tight reach ratchet is a handy tool to have on hand, you are correct that it's not totally necessary. I also added a reference about which radiator line to disconnect to minimize spilling/mess.

Appreciate the feedback - comments like these make it easier for the next person.

When you say "the door of the EGR cooler was stuck," do you mean the EGR valve, rather than the EGR cooler? I assume a replacement EGR valve would be a lot less expensive than replacing the entire EGR cooler. Regardless, glad you got it straightened out!

Regards.
