I just installed a radiator. A tip I got from the board was to not disconnect the lines to the fan. This made it a little tricky to get the radiator in (thank goodness for help), but I didn't have to deal with losing fluid. Also the bottom radiator hose is a little tricky (just a warning). Also put the color of collant in that comes out. Red and green are not compatible. It took about 2 hours with 2 people, but I am not too experienced with cars and wasn't alot of help, so it could take you less time.
