The first thing we are going to tell you is how to remove and change the thermostat in a Chevrolet Aveo. For this you will need a list-guide that you will find below:

  1. Follow the small upper radiator hose to the intake manifold of your Aveo. Connect the hose to the plastic housing of the thermostat, squeeze the clamp tabs together with a pair of pliers to release the tension on the clamp. With the tabs tightened, pull the hose out of the thermostat housing and hold it vertical to force excess fluid into the radiator. If a small amount of fluid drains into the engine, wipe it off with a towel.
  1. Remove the two 12mm bolts that secure the housing to the intake manifold.. Lift the casing up to remove it from the socket.
  1. Discard the O-ring and thermostat.
  1. Install the new thermostat in the intake manifold. One end of the thermostat has a spring. This end is inside the manifold, while the other end sticks out of it.
  1. Put the new o-ring around the thermostat. Because the gasket is rubber and not paper, there is no residue from the old gasket to clean up before installing the new gasket.
  1. Put the new cast metal thermostat housing over the thermostat and secure it with the 12mm bolts.
  1. Finally slide the hose over the thermostat housing and fix it with the clamp.
