  Q: How to replace the thermostat on a 1.6L engine on Chevrolet Tracker?

  A:

  Starting by draining engine coolant and taking off the Thermostat Housing clamp leads to removing the Radiator Hose before accessing the Thermostat. Three bolts fix the Thermostat Housing to the Intake Manifold so you must remove them before taking out the Thermostat and its o-ring from the housing. Clear away rust and residue from both the Thermostat Housing and the Intake Manifold connection areas afterward check the Thermostat. During setup of the new Thermostat, carefully place the air bleed valve at the engine's upper section before inserting the Thermostat into the Cylinder Head using a new o-ring. Fasten the Thermostat Housing to the Intake Manifold by applying 16 nm (12 ft. Lbs.) torque to its three bolts. Following Radiator Hose installation to the Thermostat Housing you must fill the Radiator with approved coolant before starting the engine. The coolant needs to achieve operational temperature before testing by checking otherwise hose heat along with Radiator coolant flow. After checking for cooling system leaks turn off the engine before installation of the Radiator Cap.

  Q: How to service and repair the thermostat on Chevrolet Tracker?

  A:

  The service and repair of a Thermostat requires the initial removal of engine coolant. The Radiator hose needs clamp removal from Thermostat Housing before disconnecting the hose at the housing. After detaching the three bolts holding the Thermostat Housing to the Intake Manifold you can remove the combination of Thermostat and o-ring from the housing. Thoroughly clean the Thermostat Housing along with the Intake Manifold mating areas before checking the Thermostat's condition. To install the air bleed valve on the Thermostat set it near the engine top before installing the Thermostat correctly into the Cylinder Head with new o-ring placement. Tighten three bolts on the Thermostat Housing to 16 nm (12 ft. Lbs.) while mounting it to the Intake Manifold. After attaching the hose clamps to the Thermostat Housing you must fill the Radiator with approved coolant before starting the engine. Temperature your cooling system properly by waiting until both coolant hoses become warm to touch while coolant flows freely through the Radiator. Start by inspecting for cooling system leaks before turning off the engine to install the Radiator cap.
