The first time, it took me about 4 hours to do the kit on a friend's 97.5 Wagon. Now that I've done it a couple of times, it's easier. Here's the short list on how to install it....
-Drain about a gallon of coolant
-Disconnect the engine batteries
-Undo the interior (nicknamed the doghouse) to get to the engine cover. This includes disconnecting all your AC and electrical harnesses to the engine computer (which is mounted on the engine cover)
-Open the engine cover
-Remove the turbo and manifold heat shield
-Remove the blocking plates over the #7 and #8 engine cooling ports
-Clean the gasket remnants off
-Install the new blocking plates with fittings
-Route hoses and install hoses to blocking plates
-Cut heater return line. Fit T to heater return line.
-Install hoses to T and then to heater return line T. Make sure hoses do not contact Glow Plug controller relay, or you'll melt your electrical system.
-Tighten everything one time more, and then add a gallon of new coolant into engine.
-Test drive vehicle (with engine cover off) to check for leaks
-Reinstall engine cover, doghouse, and interior trim.
Once I get the Arizona Hummer Owners Group web site back online (it's a victim of Hurricane Javier thanks to lightning storms that hit Phoenix), I can send you the link on the review that I wrote on it. It goes into far more detail....
You don't need special tools at all. A screwdriver, some Loctite Red Gasket sealant, a metric and a SAE basic mechanics set, and a utility knife will function.
You'll be safe once you get it back into Canada. Be aware that you might have an easier time of it buying a Hummer that's already in Canada.....There's a guy on EBay selling one in the Prince Edward Island area for 40kCDN at current bid.

I had a quick question about the cooling kit for the 8th cylinder issue...
If I purchase a wagon in Arlington Texas that hasn't had the workaround completed would it be difficult to do the upgrade in a parking lot (before I try to make the drive back to Canada) or does it require special tools etc?
How long (aprox) did it take to complete?
Thanks Again,
