The thermostat housing as the name suggests, is an engine component housing the thermostat which is known to regulate the coolant flow. The thermostat housing actually acts as a coolant outlet in most internal combustion engines. The thermostat housing is usually located on the engine block or cylinder head. As the engine coolant constantly flows, they pass through the ports located in the block and head and then through the thermostat housing and into the radiator where the coolant is cooled.
The thermostat housing may also serves as an air bleed point for the cooling system in some models. They may have a bleed valve which when loosened, allows any trapped in the block to escape. Not all the vehicles have this feature, but when present it came improve the performance of the thermostat system as well as the entire engine.
Thermostat Housing: Standalone And Integrated Models
There are two types of thermostat housing. They are based on Standalone models and the integrated thermosat models. Both standalone and integrated thermostats operate in a similar way. Let us see what they do. They actually provide necessary warm up time for the engine by delay the circulation of engine. The mechanism is such that the thermostat housing on the engine side has a little wax filled cylinder that will start to melt only after the engine reaches the thermostat design temperature (approximately 180 degree Fahrenheit). When the engine is cold, the small rod connected to a valve is closed. The wax expands on melting, pushing the rod which in turn opens the valve. This allows the coolant to flow. This operation is similar for both standalone and integrated models.
Though they operate in a similar way, over the years it is found that integrated thermostat housings have some advantages than the standalone counterparts. Overheating issues can lead to failure of the thermostat housing. It is not a hectic task to find the thermostat or thermostat housing. There are many market models available. However, it is difficult to find the correct housing which is best suited for your thermostat. It is also costly hunting down the correct one.
Now, with the introduction of integrated units this is no longer a problem as the thermostat and the housing were integrated into a single unit. This enables the mechanic to quickly and easily replace the entire unit as and when needed. The process requires no special tools and so you need not worry as is the case with standalone thermostat.
Materials Used
Thermostat housings are usually available in plastic, aluminium and steel. Plastic counterparts are not so long lasting. They must be molded from materials with good hydrolysis resistance and dimensional stability so that there is no failure. Optimal performance also calls for good material strength and stiffness. If these criteria are not met with, then these can lead to engine damage and immobility.
