Understanding the Heater Tap in the 2016 Subaru Forester

When it comes to the 2016 Subaru Forester, the concept of a heater tap might come up for those digging into the vehicle's heating and cooling systems. However, this model does not actually use a heater tap as part of its heater system. Instead, Subaru has designed the 2016 Forester with a different approach to managing engine coolant flow through the heater core.

A heater tap is commonly used in some vehicles to regulate the flow of hot coolant into the heater core. It essentially acts like a valve that controls whether hot engine coolant circulates through the heater core, which allows or stops the heating of air before it enters the passenger cabin. This setup works by allowing the heater tap to open or close depending on the temperature settings, providing precise control over cabin heating.

So, why doesn't the 2016 Subaru Forester have a heater tap? The answer lies in the vehicle's cooling and heating system design. Subaru uses what's called a heater control valve system or a heater control blend door system that operates without a traditional heater tap. In the 2016 Forester, instead of using a heater tap, the heating system manages temperature by controlling the blend door inside the HVAC (heating, ventilation, and air conditioning) box. This blend door modulates how much hot air from the heater core mixes with cooler air before reaching the cabin, rather than stopping or starting the flow of coolant itself.

This design eliminates the need for a heater tap because the coolant is constantly flowing through the heater core when the engine is running. Temperature control is achieved by internal airflow regulation rather than coolant flow control. This approach reduces the number of mechanical components under the bonnet, which in turn decreases potential failure points, improves reliability, and makes maintaining the heater system simpler overall.

For vehicle owners and mechanics, this means there is no heater tap to inspect, maintain, or replace on the 2016 Subaru Forester. If a Forester's heating system isn't working properly, the issue is more likely to be related to other elements such as the blend door actuator, thermostat, coolant levels or quality, radiator, heater core, or the HVAC control system itself.

Since a heater tap is not fitted, focus during servicing should be on these components to ensure efficient heating performance. Checking that the coolant system is in good shape is crucial since proper coolant circulation is fundamental to the heater core's operation.

Regular maintenance tasks for the Subaru Forester's heating system include:

• Ensuring the coolant is topped up and replaced according to the manufacturer's schedule.
• Inspecting the thermostat for correct operation to avoid the engine running too cold or overheating, both of which impact heating efficiency.
• Verifying the heater core is free from blockages or leaks since coolant is always flowing through it.
• Confirming blend doors and actuators function correctly to regulate cabin temperature.
• Cleaning or replacing the cabin air filter to ensure good airflow inside the vehicle.

If a Forester owner experiences poor cabin heating, after basics such as coolant levels and thermostat function are checked, the next step would be a diagnostic of the HVAC control system and blend door actuators. Since there is no heater tap to inspect, problems like cold air flow might come down to a faulty blend door or a heater core issue rather than valve failure.

Simply put, the heater tap is a part that's commonly associated with older or more traditional cooling and heating circuits where stopping and starting coolant flow is necessary to control heat output. Subaru's approach in the 2016 Forester corners the market on reliability by utilising constant coolant flow paired with internal air mixing controls.

For those who might come across discussions or listings involving heater taps in vehicles, it's important to note that not all cars need or use them. The Forester's design is a great example of a system that has evolved to reduce mechanical complexity. So while no heater tap is to be found in this model, the heating system still delivers on comfort thanks to other well-thought-out components.
