How to Maintain a Thermostat in a Cooling System on Dodge Ram 2500?

Always check to see if the radiator draincock is tight before starting work on the service, otherwise, there is a risk of getting seriously burned by hot coolant. Remove the coolant from your vehicle into a clean bucket so it can be saved if it seems clean and then uncouple the battery negative wires. Take out all the coolant from the system until it is below the thermostat. To service constant tension hose clamps, apply the special clamp tool or use the Snap-On tool (numbers 6094 or HPC-20, respectively) and remember to wear safety glasses as you work. You should only replace constant tension clamps by using those from the same manufacturer with the same matching number or letter. Loosen the clamp securing the radiator hose to the thermostat housing and unfasten the hose. After that, undo the three bolts connecting the thermostat to the cylinder head and remove the water outlet connector. Clean out any debris from the water outlet connector as well as the thermostat seat groove in the top of the housing. To fit the thermostat, place it in the top groove of the thermostat housing, add the water outlet connector and bolts and tighten everything to 24 Nm (18 ft. lbs.). Fix the upper radiator hose, attach the clamp, place the cooling system grille over the intake side, fill the cooling system with coolant and resecure the battery negative cables. Begin the engine to observe any leaks from the cooling system, as well as the way the thermostat is working.
