- disconnect the battery
- drain coolant and motor oil
- remove the fan cover plate (part of fan shroud)
- remove the viscous coupler and fan
- pull up the fan shroud - it is kept by the spring clips on top, and slides in the groove at the bottom of the radiator
- disconnect the coolant hoses (two large ones and two small ones)
- unscrew the oil cooler fittings and disconnect the hoses
- remove the top radiator brackets (one at the driver side also serves as a mount for P/S reservoir)
- pull out the radiator.
... clean up the toxic spill
