Parts for your 2016 Subaru Forester-Thermostat

Understanding the Thermostat in Your 2016 Subaru Forester

The 2016 Subaru Forester definitely uses a thermostat as an essential part of its cooling system. Like most modern vehicles, the thermostat plays a crucial role in making sure the engine runs at the right temperature. If you own a 2016 Forester or are keen on servicing one, understanding what the thermostat does and when to replace it is really handy.

So, what exactly is the thermostat? Essentially, it's a valve housed within the engine's cooling system that regulates the flow of coolant between the engine and the radiator. When the engine is cold, the thermostat stays closed. This means the coolant doesn't flow to the radiator and allows the engine to warm up quickly. Once the engine reaches the right operating temperature, usually around 88-95 degrees Celsius, the thermostat opens up. This allows coolant to circulate through the radiator where it cools down before cycling back into the engine. The thermostat ensures that the engine temperature is kept within an optimal range.

This temperature regulation is critical for several reasons. Firstly, running the engine too cold is inefficient and causes more wear and tear, as the oil doesn't lubricate properly. Secondly, if the engine runs too hot, it can lead to overheating, damage to engine components, and even breakdowns. The thermostat is that little hero making sure everything stays balanced.

When it comes to the 2016 Subaru Forester, the thermostat is a straightforward, reliable component. It's typically found mounted on the engine block or cylinder head, connected to the upper radiator hose. The part itself usually includes a temperature-sensitive wax pellet inside a metal housing. As the wax melts with heat, it pushes a rod that opens the valve and allows coolant flow. A simple but clever design that's been used across many vehicles.

On servicing your 2016 Forester, checking the thermostat should be part of routine maintenance, especially if you've started noticing any cooling system issues or strange engine temperatures. The thermostat is a wear item that can sometimes stick closed or open due to age, corrosion, or debris. A stuck closed thermostat can cause overheating, while a stuck open one might keep the engine running cold, leading to poor fuel economy and increased emissions.

Some signs your thermostat might be struggling include:

• The temperature gauge stays unusually low on the dash even after driving for a while.
• The engine overheats quickly or often.
• Poor heater performance inside the cabin on cold days.
• Coolant leaks around the thermostat housing.
• Fluctuating temperature gauge needle movements.

If any of these signs appear, it's a good idea to get the thermostat checked by a qualified technician. Replacement is usually the best course of action if the thermostat is faulty, as the part itself is relatively inexpensive and the fix helps avoid bigger, costly repairs from engine overheating or poor running conditions.

The replacement process in a Subaru Forester is pretty straightforward for a mechanic. It involves draining the coolant to a safe level, removing the thermostat housing, swapping out the old unit for a new one, and then refilling the coolant system. After replacement, it's important to bleed the cooling system to remove any air pockets, ensuring proper flow and accurate temperature regulation.

Using genuine Subaru parts for the thermostat and coolant is recommended, as these components are designed to meet specific tolerances and temperature specifications for the Forester's engine. Also, regular servicing intervals where the coolant system is inspected, and the thermostat function verified, will help keep the vehicle running smoothly.

In Australia, where weather can range from chilly winters to hot summers, a functioning thermostat becomes even more vital. It can make a difference to cabin comfort on cold mornings and prevent overheating during long drives or when towing. Subaru Forester owners who stick to recommended service schedules and don't ignore temperature warning signs are more likely to enjoy trouble-free motoring.

So, if you haven't thought much about the thermostat in your 2016 Subaru Forester before, it's worth adding to your car care checklist. It's a small part that makes a big difference in how your engine performs and lasts. Replacing or maintaining the thermostat as needed is a smart way to protect your investment and keep your Forester going strong for many more kilometres.
