The thermostat is a crucial electrical component for the engine, specifically for its temperature. If it does not function properly, it can cause serious damage, such as burning the head gasket.

Let's see how to proceed with its replacement: After opening the hood, remove the radiator cap and start by disconnecting the rubber hose that connects the radiator to the engine. Next, remove all the bolts securing the thermostat to the right of the engine.

Complete the job by draining the coolant from the aforementioned radiator, optionally using an electric pump, allowing you to remove the thermostat from its housing and replace it with a new one.
