Any responsible homeowner knows how the different appliances installed in the house works. This includes the radiator thermostat. If you are a new homeowner, you probably have to be acquainted with this indispensable equipment that helps to adjust the heat and temperature settings in your home as well as how to change it when the time comes to doing so.


What a Radiator Thermostat Does


As mentioned earlier, a radiator thermostat (interesting to know is that the Dutch term is Radiator thermostaat) is very important to have in one’s home. It serves as the control when the coolant used for heat management is sent towards the engine when it is in operation. Basically, it is like the air traffic controller for the way heat is distributed in your home. There might be a reason to change the radiator thermostat in your home – such as when the parts are already worn out or if you want to make the performance a low-temperature one. Fortunately, it is not very hard to replace the radiator thermostat so you can do it yourself and not rely on a repairman for the job.


The Steps to Follow

There are some steps involved in changing the radiator thermostat of your home. First, you have to drain it so that the level of the fluid is below the radiator thermostat’s position. Then, follow the coolant supply line of the main engine as it detaches in the back. You will find the radiator thermostat is located in the engine, right in between the neck of the thermostat and the supply home. Draining the cooling fluid just right below the radiator thermostat’s location will ensure that you will not end up losing coolant.

Next, you have to loosen the clamp of the hose. It might be difficult to reach out to the fasteners at first, so you might need the right screwdrivers and tools to loosen it. A long screwdriver will make it easier for you to access the fasteners and the screws. A pair of pliers, on the other hand, is used to easily remove the top from the radiator.

Now you have to loosen the fasteners of the thermostat neck using a ratchet wrench and any of the following extensions: three inch, six inch or twelve inch. Turn it in a counter clockwise motion and loosen it one by one until you get all the fasteners off completely. Clean the surface of the gasket as this is where you will be attaching the new radiator thermostat.


Mount the new thermostat in the front part of the engine over the position and then secure it again using your ratchet wrench and the extension. Screw in the bolts tightly into place then use the long screwdriver to tighten your hose clamp. Finally, attach the end of the radiator’s coolant supply hose and secure it using your factory hose clamp. Fill it up the entire radiator tank with half distilled water and half with coolant until the entire tank is full, then start the engine. This is all it takes to change your radiator thermostat.
