How to replace the thermostat on Chevrolet Colorado?

Start by draining the cooling system then elevate the vehicle just enough so you can reach the Thermostat Housing through the wheelhouse. The left wheelhouse liner comes off first followed by using hose clamp pliers (J 38185) to disconnect the radiator inlet hose from its position at the Thermostat Housing. The next step requires removal of Thermostat Housing bolts followed by separation of the Thermostat Housing from the engine block. Both the Thermostat Housing and engine block sealing surfaces need cleaning before inspection. Screw the Thermostat Housing onto the engine block after which install and tighten the Thermostat Housing bolts to 10 nm (89 inch lbs.). You need hose clamp pliers (J 38185) once again to do the radiator inlet hose installation onto the Thermostat Housing then reinstall the left wheelhouse liner followed by vehicle lowering together with cooling system filling and ending with leak inspection after starting up the engine.
