You need only to drain off a couple quarts of coolant to change the thermostat.
The drain plug is at the bottom passenger side of the radiator. It takes a 1/4 inch extension to fit into the head to turn it.
The drain valve will be located on the bottom of the radiator, on one side or the other. It's a little plastic tab. If you need to drain the radiator, pull the lower hose if you're not replacing the radiator so that you don't take the chance on breaking that stupid plastic drain valve.
The drain plug is located on bottom right side of rdiator if you are standing in front of vehicle On the very bottom of radiator
Start off by unhooking the radiator hoses from the block and drain them. Then dissassemble your intake. then you star taking everything off of the moter hose and wire wise that are attached to the truck. then start taking out bolts.
Assuming you are asking about the radiator coolant drain, it should be on the passenger side under the lower radiator hose. It should take a 1/4" square drive to open it.
