First drain it from the drain cock, then unbolt the fan shroud and remove it (this may require you to remove the water pump fan), next remove the radiator hoses (top and bottom), remove the overflow hose, undo the transmission cooler lines (for automatic transmissions only). Now you can unbolt the radiator and lift out. Installation is reverse of removal.
Remove the serpentine belt. Drain the water from the radiator. Remove the radiator hose from the water pump. Remove the water pump retaining bolts. Reverse the process to install the new water pump.
Remove the bottom radiator hose. Put a garden hose into the top of the radiator. Allow the garden hose to run until the water coming out of the bottom of the radiator is clear.
It's an aluminum radiator with plastic tanks.
In the first generation SC2 the horn is located in front of the radiator.
You must remove the rear package tray.
Yes; it's on the coolant reservoir. The entire coolant reservoir on the Saturns is pressurized.
Very carefully
Look for a removable housing at the engine end of the upper radiator hose you will have to drain the radiator fluid first because the thermostat is fairly low Follow the lower radiator hose on the passenger side to the engine its in a housing so you have to remove the radiator hose then the thermostat cover with the 2 bolts
check link below,this is for a gen 2 but is very similar to your gen 1.
the ONLY access to the radiator is the overflowreservoir on the passenger side it has a big black cap and its right above the windshield washer fluid tank
Jack up the pasenger side of the car. Remove the wheel. remove the rear plastic shield. There it is!
