Perform this work only on a cold engine.

Disconnect the negative battery cable.
Set the heater control to MAX heat.
Remove the expansion tank cap.
Place a suitable drain pan into position. Open the cock on the right-hand side of the engine block. Fit a hose to the cock to collect the coolant. Open the radiator draincock.
Close the drain cocks when the coolant is completely drained.
Remove the cooling fan.
Remove the cooling fan shroud.
Disconnect the upper and lower radiator hoses
On vehicles equipped with automatic transmissions, disconnect the transmission oil cooler lines at the radiator. Plug the lines immediately. Catch the spillage from the radiator in a separate pan.
Some vehicles are equipped with a temp sensor on the drivers side top of the radiator, if equipped remove the connector.
Remove the radiator retaining bolts and brackets.
Remove the radiator assembly from the vehicle.

To install:

Place the radiator into position and install the retaining bolts.
On automatic transmission vehicles, connect the oil cooler lines.
Install the fan and shroud.
Install the lower and upper radiator hoses.
Connect the expansion tank hose. Make sure that the overflow hose is clear of the fan and is free of any sharp bends.
Fill the cooling system through the expansion tank, with a 50 percent antifreeze, 50 percent water solution.
Connect the negative battery cable.
Run the engine until normal operating temperature is reached.
Bleed the cooling system.
Check for leaks.
Top up the cooling system, as required.
Replace the cap.
Check and top up the automatic transmission fluid level.
