The mechanical thermostat found inside of the intake manifold on your 2001 Toyota Camry regulates the operating temperature of the engine. It does so by compressing a spring located inside the thermostat as the temperature of the radiator fluid rises. As the spring compresses, it allows more fluid to flow through the engine and the radiator. The increased flow helps to cool the fluid and, therefore, the engine. If the thermostat stops working, the easiest way to correct the issue is to replace it with a new one.

Tools Used[edit]

12 mm socket
Thermostat gasket

Change a Thermostat[edit]

  • Open the hood and secure it with the hood prop. Allow adequate time for the engine to cool off. Radiator fluid reaches very high temperatures and will burn you if your skin comes in contact with it. A half-hour is usually adequate.
  • Remove the radiator hose from the thermostat housing. To locate the thermostat housing, follow the hose from the radiator to the location where the hose mounts to the intake manifold. The metal housing to which the hose mounts is the thermostat housing. Remove the hose by loosening the band clamp with a pair of pliers and then pull the hose off the housing.
  • Remove the two bolts that secure the thermostat housing to the intake manifold of the Camry with a 12 mm socket. Lift upward on the housing to break it loose form the intake.
  • Disconnect the wiring harnesses from the starter and the starter solenoid. The solenoid bolts to the starter.
  • Lift the old thermostat out of the intake and then scrape the old gasket material off the surface of the intake manifold and the bottom of the thermostat housing. Do not get any gasket material into the hole.
  • Place the new thermostat into the intake manifold. The end with the spring sits inside of the thermostat and the end with the long pin sits inside of the thermostat housing.
  • Place a new thermostat gasket onto the intake manifold of the Camry and secure the thermostat housing by bolting it into place.
  • Slide the radiator hose onto the thermostat housing and secure it with the radiator hose clamp.
