Where the top radiator hose connects to engine. It will be under that flange.
Follow the top big radiator hose to the intake manifold and its right there where they meet
SOURCE: need location of thermostat ,over heating.
On the 2.2 engine it is located on the lower radiator hose water pump side.
Remove the two retaining bolts for on the housing
Separate the housing halves to access the thermostat
Pull the thermostat out to remove it from the housing
The thermostat has an O-ring which goes around the center
Thoroughly clean the mating surfaces of the thermostat housing
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 silicate coolant (green) 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.
Good luck and hope this helps.
Trace the upper radiator hose to the mounting area on the intake manifold. Loosen the hose clamp on the manifold end of the hose and remove the hose. Pull the thermostat out of the intake manifold.
