I need to change my thermostat on a 1999 chevrolet cavalier where is it located

Fig. 1: The thermostat is located in the lower radiator hose on the 2.2L engine



When adding coolant, it is important that you use GM Goodwrench DEX-COOL® (orange colored, silicate free) coolant meeting GM specifications. On these vehicles, if silicated coolant is added to the system, premature engine, heater core or radiator corrosion may result. In addition, the engine coolant will require change sooner; at 30,000 miles or 24 months.
  1. Disconnect the negative battery cable.
  2. Properly drain and recover the coolant until the level is below the thermostat.
  3. Unfasten the coolant outlet-to-inlet manifold attaching bolt and nut, then remove the outlet.
  4. Remove the thermostat. Clean the inlet manifold and outlet mating surfaces.

To install:
  1. Install a new O-ring onto the thermostat
  2. Place the thermostat in the inlet manifold.
  3. Attach the coolant outlet to the inlet manifold, using the bolt and nut. Tighten to 89 inch lbs. (10 Nm).
  4. Refill the engine cooling system.
  5. Connect the negative battery cable, then start the engine and check for coolant leaks.
Hope this help (remember rated and comment this).

I do not know where the '98 Cavalier 2.2 L engine thermostat is

Open the hood and trace the upper radiator rubber hose to where it ends. That is where you should find the thermostat. If it is not there, it is apparent that the previous owner could have removed it for some reasons.
Notice how the thermostat was previously installed, and use that as a guide when you replace it back.
