SOURCE: where is the thermostat located

3.1L and 3.3L Engines

  1. Disconnect the negative battery cable.
  2. Drain the cooling system to a level below the thermostat housing.
  3. Remove the air cleaner assembly.
  4. Disconnect the surge tank line from the thermostat housing.
  5. Remove thermostat housing-to-intake manifold attaching bolt and nut, then remove the housing.
  6. Remove the thermostat.
To install:
  1. Clean all gasket surfaces completely.
  2. Insert the thermostat in the intake manifold.
  3. Attach the thermostat housing to the intake manifold.
  4. Install the mounting bolt and nut. Tighten to 18 ft. lbs. (25 Nm) for the 3.1L engine. For the 3.3L engine, tighten to 20 ft. lbs. (27 Nm).
  5. Install the air cleaner assembly.
  6. Connect the surge tank line to thermostat housing.
  7. Refill the cooling system.
  8. Connect the negative battery cable, remove the radiator cap, then start the engine. Allow the engine to run with radiator cap removed, until the upper radiator hose becomes hot (thermostat open). With the engine idling, add coolant to the radiator until the level is up to the bottom of the filler neck.
  9. Install the radiator cap, making sure the arrows line up with the overflow tube.

Where is the thermostat located on 1997 Olds achieva?


If you have the 3100 v6 engine, the thermostat is located behind an aluminum housing behind the exhaust crossover tube almost directly below the throttle body. If you have the 2.4 dohc engine, it is under a steel housing on top of the waterpump which is underneath the exhaust manifold on the back side of the engine.

Engine light stays on a 97 olds achieva sl


Engine light stays on, low coolant light stays on , recently had a plastic housing replaced that was leaking, it was linked to thermostat, tranmission coolant,heater ect. Had the thermostat replaced also. Level of coolant is fine, does't overheat anymore, but now the starter wants to spin a couple of times and then it starts. The car has no rust, would like to hang on to it
