Instructions to Replace the Thermostat

Detailed instructions - Locate the thermostat in the engine compartment; for convenience, remove the plastic cover near the valve cover. First, drain the cooling system using the drain located behind the front bumper on the lower right side when facing the vehicle: to do this, connect the drain outlet to a sufficiently large container (1.8 gallons) using a plastic hose; then open the drain by unscrewing the dedicated valve to allow the coolant to flow into the container. To facilitate drainage, keep the ignition on and set the internal heating controls as if it were to emit warm air. At this point, working on the plastic hose (made of two sections) of the thermostat, detach the metal retaining ring and remove the lower part of the hose. Now unscrew the two screws that secure the upper hose to the engine block and then, pulling it outward, extract the thermostat. Take the new replacement part, which will come with the two necessary gaskets for installation: a cylindrical one to apply in contact with the plastic hose and a square one to apply near the metal valve. Now insert the new thermostat into the engine block by reversing the procedure, tighten the screws of the upper hose, and fit this hose into the other section of the hose. Tighten the retaining ring. Returning to the undercarriage, close the drain valve by screwing it back in and fill the coolant reservoir to the "max" mark, closing the corresponding cap. Finally, reattach the plastic cover removed at the beginning.
