I'm in the process of changing out the water pump on my 1991 Land Cruiser, it's a pretty straight forward process. However, some of the hoses on the pump do require small hands to r&r. There was no need to remove the radiator. My hands are beat up pretty bad though. I have all the air tools I need, but I haven't turned on the compressor 1 time. Just taking my time, almost done!
