Heater Tap on the 2013 Subaru Exiga: What You Need to Know

The 2013 Subaru Exiga does not use a traditional heater tap in its heating system. Unlike some older vehicles or certain other models where heater taps were common, the Exiga employs a more modern approach to controlling the flow of hot coolant to the heater core, making the heater tap unnecessary. This design choice is rooted in advancements in automotive heating systems and coolant flow management.

So, why is a heater tap not relevant for the 2013 Subaru Exiga? Simply put, a heater tap is a manual valve used to regulate the flow of engine coolant into the heater core, allowing the occupants to control the temperature inside the cabin. Older cars required this mechanical valve to open and close coolant flow for the heating system. Modern vehicles, including the Exiga, do away with that manual mechanism entirely.

The reason behind this is that the Subaru Exiga uses a heater control valve integrated into the vehicle's climate control system. This valve operates electronically or through a vacuum system controlled by the vehicle's HVAC (heating, ventilation, and air conditioning) controls. This setup offers more precise regulation of coolant flow than a simple manual tap, which improves passenger comfort and system efficiency. It also reduces wear and tear since there is no manual operation or mechanical parts that can easily seize or fail.

In the context of the Exiga, this means there is no dedicated heater tap valve to service or replace during regular maintenance. The cooling and heating system relies on other components such as thermostats, coolant hoses, and the heater core itself. Any flow control is handled internally by the electronically controlled valve, which is generally more reliable and requires less manual intervention.

Even though there is no traditional heater tap, it is still essential to keep the heating system in good shape on the 2013 Subaru Exiga. Here are some tips and considerations to ensure the heating system works smoothly:

• Regularly check and replace the engine coolant as per Subaru's service recommendations. Old or contaminated coolant can cause blockages or corrosion in the heater core and cooling system components.
• Inspect hoses and connections periodically for any signs of leaks, cracks, or wear. Damaged hoses can lead to poor coolant flow, which affects the heater's performance.
• If heaters produce weak heat or the cabin takes a while to warm up, it might indicate an issue with the thermostat or the heater core rather than a heater tap, since that part doesn't exist in this model.
• Clogged heater cores can cause similar symptoms to what a faulty heater tap might once have caused, so it's good to flush the cooling system when the heater performance drops noticeably.
• Ensure the HVAC controls and any related electronic actuators are functioning correctly. Since the valve controlling heater flow is electronically managed, faulty actuators can result in no heat delivery at certain settings.

If, during servicing, any issues are found related to the flow of coolant through the heating system, technicians will address them by replacing or repairing the heater control valve assembly or other relevant components instead of a heater tap. In Subaru Exiga models, these parts tend to be more durable and last longer than old-style heater taps, but no system is immune to wear over time.

In terms of maintenance, it's a good idea to follow the vehicle's manufacturer guidelines closely. Cooling system service intervals generally involve coolant replacement every few years or after a certain number of kilometres to prevent corrosion and keep the system operating efficiently. Keeping the heater control valve, thermostat, and heater core clean and functional helps avoid any sudden loss of heat during colder months.

Because the heater flow is electronically controlled, if any repairs or replacements are needed, it may require diagnostic equipment to pinpoint the issue accurately. This is a step beyond what a simple heater tap valve replacement involves but reflects how heating systems have evolved to blend comfort and technology seamlessly.

For Subaru Exiga owners keen to keep their heating working well, the absence of a manual heater tap means fewer fiddly mechanical parts to worry about, but it also means paying attention to coolant condition, heater core cleanliness, and the proper function of HVAC controls. Taking care of these elements will ensure the cabin stays cosy and comfortable throughout the seasons.

So, while the 2013 Subaru Exiga doesn't have a heater tap in the classic sense, understanding how the modern heating system works and maintaining it properly provides peace of mind. The system's design takes the hassle out of manual valve adjustment and lets drivers and passengers enjoy efficient warming with minimal fuss.
