Thermostat Housing Failure in Your Mercedes at S Figueroa St. Gardena

Mercedes Thermostat Housing

One of the most important factors that needs to be regulated in an engine is temperature in order to ensure that the engine runs efficiently. When the engine runs, the temperature also increases, and if left unchecked, it can create a myriad of problems in the engine.

In sophisticated vehicle models such as the Mercedes, it is vital that all the required conditions in the engine are met for the vehicle to produce excellent performance.  The Mercedes is highly famed for its impressive performance, as it is one of those vehicles whose manufacturer has consistently ensured that their cars have the most efficient and powerful engines.

Even in keeping up with this high standard, Mercedes engines, like all other engines, have smaller components that work in unison to ensure engine efficiency. The thermostat housing, for instance, plays an important role in ensuring that the temperature in the engine is regulated. When it has a failure, it can negatively impact your engine. Let’s take a look at the thermostat housing failure.

What it Does

The thermostat housing, just as the name suggests, is a component in the engine that houses the thermostat. The thermostat housing is an outlet through which the coolant passes through as it goes in and out of the engine compartment. This coolant is responsible for taking away part of the heat that is produced while the engine is running in order to prevent overheating that can cause severe damage to the engine.

Coolant does not always flow in and out of the engine. This is because the engine has to heat up to a certain temperature before the wax that is usually contained in a cylinder is warmed up so it starts to melt. When this wax melts, it expands and causes a small rod that is attached to a normally closed valve to push the valve open and allow coolant to pass through.

The thermostat housing essentially regulates the flow of this coolant into the engine, where it absorbs some of the heat that is produced in the engine. The coolant then flows into the radiator, where it is cooled off before the process is repeated. The thermostat housing also protects the thermostat in the engine and prevents it from being exposed directly to the extreme heat in the engine.

Causes of Thermostat Housing Failure

The main cause of thermostat housing failure in your Mercedes is degradation of the rubber hose that the thermostat housing is made of. The constant expansion and contraction of the rubber hose can cause premature wear, which can result in cracks that will cause the coolant to start leaking. This wear is inevitable, especially after covering several hundred thousand miles in your car.

Signs of Thermostat Housing Failure

Coolant is usually a shade of brownish-red with a sweet distinctive smell. These leaks come from cracks in the housing through which coolant flows.

Overheating Engine
