The thermostat housing is one of those parts of a car that doesn’t get much attention. But guess what: a glitch in a part that seems so trivial can contribute to an array of different issues that you never knew existed. So if your Mercedes’ thermostat housing is leaking, don’t take it for granted. Act promptly to trace the leak to its source and get it fixed before it turns into an expensive repair. Listed below are some of the reasons why a vehicle’s thermostat housing may start leaking and things that can be done about it.

Thermostat Housing: What Is It & Why Your Mercedes Need One?

In a nutshell, the sole purpose of a vehicle’s thermostat housing is to encase the thermostat- the part that regulates coolant circulation between the engine and the radiator. Made of aluminum and/or plastic, thermostat housing is designed to withstand extreme temperature and facilitate controlled coolant circulation between the engine and the radiator. It has two ports- one linked to the radiator while the other one is connected to the engine.

Although it is designed to withstand extreme temperature, it can get damaged over time. A part of such significance, if wears out, can contribute to a plethora of cooling system related-issues and may even lead to engine overheating. So if it occurs to you that there is something off with your Mercedes’ thermostat housing, get to its bottom ASAP.

Signs Your Mercedes’ Thermostat Housing Is Leaking

So if you notice coolant puddle under your Mercedes, take swift action before the crack on the housing empties your Mercedes’ coolant reserve. In addition to a cracked thermostat housinga blown radiator hose, a defective radiator tube, and a fractured coolant seal can also contribute to coolant leak in a vehicle.

Sign #2- Engine overheating

Isn’t it obvious? A crack on the thermostat housing of your Mercedes can result in unsanctioned coolant loss. Depleted coolant level could significantly limit the cooling system’s ability to perform its assigned task- which is to keep the engine temperature within a specific range. As a result, the engine will run hot- and may eventually overheat. Obstructed coolant flow because of a defective thermostat housing could also contribute to engine overheating in a vehicle.

Sign #3- Visible wear and tear
