How Do You Change the Thermostat on a Kia Sedona?

Changing the thermostat on a Kia Sedona involves draining the coolant from the cooling system, removing the housing and replacing its gasket. The coolant should be flushed after replacing the thermostat to ensure there is no air left inside the cooling system.

The thermostat is a special component inside the cooling system that controls the flow of coolant from the radiator to the engine. Thermostats are rated at certain temperatures. When the cooling system temperature reaches that limit, the valve in the thermostat opens, allowing the coolant to flow into the engine. This lets the engine warm up quickly and efficiently.

When a thermostat fails, the engine can overheat. The thermostat should be quickly replaced to avoid any serious wear on the engine. The following instructions explain how to replace a thermostat on a Kia Sedona.

  1. Drain the coolant
  2. The thermostat is located at the end of the top radiator hose. Remove the drain plug from the radiator and flush the coolant into a pan.

  3. Remove the Upper radiator hose
  4. Loosen the clamps that connect the upper radiator hose to the housing and remove the hose.

  5. Remove the thermostat housing
  6. Loosen the thermostat housing mounting bolts. Remove the housing and pull the thermostat from it.

  7. Replace the thermostat
  8. Inspect the new thermostat and install it with a new gasket. Mount the housing and upper radiator hose. Then pour new coolant into the radiator.
