QuestionI have a leaky radiator and thought it be smart to change it out. I also have an electric fan installed in the shroud. Anything I should know about the removal and install? It seems pretty easy. Just drain the fluid through the bottom of the radiator, remove the shroud, remove the bottom and top hoses, remove the external fill tank and those hoses, reverse the procedure. Where do I fill the new coolant fluid at and should i use straight coolant or mix it 50/50? Also, my electric fan came with a probe that goes through my radiator core. I don't like that method. Is there another way? A probe that reads the water temp perhaps?
Thanks!!!

Disconnect battery negative cables.
WARNING: DO NOT REMOVE THE CYLINDER BLOCK DRAIN PLUGS OR LOOSEN THE RADIATOR DRAINCOCK WITH THE SYSTEM HOT AND UNDER PRESSURE. SERIOUS BURNS FROM THE COOLANT CAN OCCUR.
Drain the cooling system (Refer to 7 - COOLING - STANDARD PROCEDURE).
WARNING: CONSTANT TENSION HOSE CLAMPS ARE USED ON MOST COOLING SYSTEM HOSES. WHEN REMOVING OR INSTALLING, USE ONLY TOOLS DESIGNED FOR SERVICING THIS TYPE OF CLAMP. ALWAYS WEAR SAFETY GLASSES WHEN SERVICING CONSTANT TENSION CLAMPS.
CAUTION: A number or letter is stamped into the tongue of constant tension clamps. If replacement is necessary, use only an original equipment clamp with a matching number or letter and the correct width.
Remove the hose clamps and hoses from radiator.
Remove the coolant reserve/overflow tank hose from the radiator filler neck.
Remove the coolant reserve/overflow tank (5.9L) or the coolant degas container(3.7L/4.7L) from the fan shroud (pull straight up). The tank slips into slots on the fan shroud.
Unclip the power steering hoses from the fan shroud.
Disconnect the electrical connectors at the windshield washer reservoir tank and remove the tank.
Remove the fan shroud mounting bolts and pull up and out of the radiator tank clips(Fan Shroud - Gas Engine). Position shroud rearward over the fan blades towards engine.
Disconnect the transmission cooler lines from the transmission cooler, then plug the transmission lines and cooler to prevent leakage.
Disconnect the power steering lines from the power steering cooler, then plug the power steering lines and cooler to prevent leakage.
Remove the two radiator upper mounting bolts(Radiator).
Lift the radiator straight up and out of the engine compartment. Take care not to damage cooling fins or tubes on the radiator and oil coolers when removing.
NOTE: The radiator is equipped with one alignment dowel on the bottom of the outlet tank and one retaining bracket on the front side of the inlet tank. Both features have rubber insulators attached to them that must be present. The alignment dowel fits into a hole at the bottom of the front end sheet metal vertical support post and the support bracket rests on top of the lower radiator closure tube.
50/50 coolant
