Radiator Removal
Drain radiator
Remove fan blade
Remove hoses
Remove shroud brackets
Pull shroud towards the motor and hang it on the water pump pulley to get it out of the way
Shroud will only come out after radiator is removed
Disconnect transmission lines
Remove two top radiator brackets
Remove 4 top core support bolts ( 2 on each side ) then loosen 2 bottom bolts ( one on each side )
Lean core support towards front of car
Remove radiator by pulling up on drivers side first.
Best to have a helper for the last step, PG.

Mark hood hinges with tape and REMOVE HOOD! It can be done without, but you will be very happy when you are going back together if you can get access from the front. you sure dont want to gouge your pretty new radiator putting it back in. The tip about picking up the driver side of the rad first is a good tip since the lower radiator outlet is going to get hung up on the upper control arm of the suspension. Also, Never will you be in a better position to replace the bottom radiator hose than right now. Great time to change it out while you are there
