How to replace the thermostat on GMC Sonoma?

A partial drainage of the cooling system should precede Thermostat replacement. The air cleaner outlet duct must be removed initially before performing the throttle body bracket nut removal process to modify its position. First detach the water outlet housing mounting bolts on the lower Intake Manifold before removing the water outlet housing which you will set aside. First remove the gasket or o-ring and the Thermostat before cleaning all sealing surfaces between the water outlet housing and lower Intake Manifold.
