How do you change the water in a Dodge Ram truck?

Remove the bottom radiator hose from the radiator. Make sure that you have a couple of 5 gallon buckets to catch the water/antifreeze in. There will still be some in the block, but that will get the majority of it out.

My 2001 has a drain valve on the drivers side,back bottom of radiator. Make sure motor is cool, open radiator cap. Twist drain valve counter clockwise to open. After draining radiator, start engine and watch temp gauge for engine to get to operating temp and turn motor off. This will open thermostat and get most of coolant out of engine and heater coil. There may be instructions in your owners manual.
