Ford Focus>> Cooling system>> Thermostat



Remove the thermostat only on the cooled engine. If you independently do this work, you will need the following spare parts: the thermostat, consolidation of a cover of the case of the thermostat, and also the hermetic keeping elasticity for a long time and heatresistant (for example, DP300 from the Wurth company). Merge cooling liquid in pure capacity that it could be used again. You can check operability of the old thermostat, having heated up water in a pan to the moment when the thermostat valve will open. Then compare the measured water temperature in a pan to temperature which is put on the thermostat case. And still we do not advise to you to use the thermostat having an external raid from deposits of system of cooling.
