How is the thermostat changed on a Dodge 2500 V-10 Ram? It looks different from a small V-8.
THe tempature gauge barely climbs up over 130

The step are somewhat similar to a small V-8, but the housing is quite different.


Allow the engine to completely cool. Overnight is best.

REMOVAL INSTRUCTIONS
1. Disconnect negative battery cable at battery.
2. Drain cooling system until coolant level is below thermostat.
3. Remove the two support rod mounting bolts and remove support rod (intake manifold-to-generator mount).
4. Remove upper radiator hose clamp. Remove upper radiator hose at thermostat housing. These clamps are spring loaded. Prodeed with caution.
5. Disconnect the wiring connectors at both of the sensors located on thermostat housing.
6. Remove six thermostat housing mounting bolts, thermostat housing and thermostat.

INSTALLATION

1. Clean mating areas of intake manifold and thermostat housing.
2. Check the condition (for tears or cracks) of the rubber thermostat seal located in the intake manifold. The thermostat should fit snugly into the rubber seal.
3. If seal replacement is necessary, coat the outer (metal) portion of the seal with gasket sealer. Install the seal into the manifold.
4. Install thermostat into recessed machined groove on intake manifold.
5. Install thermostat housing.
6. Install housing-to-intake manifold bolts. Tighten bolts to 25 Nm (0.20 inch lbs.) torque. CAUTION: Housing bolts should be tightened evenly to prevent damage to housing and to prevent leaks.
7. Connect the wiring to both sensors.
8. Install the upper radiator hose and hose clamp to thermostat housing.
9. Install support rod.
10. Fill cooling system.
11. Connect negative battery cable to battery.
12. Start and warm engine. Check for leaks.
