Heater Tap and Its Relevance to the 2019 Mitsubishi Eclipse Cross

When it comes to the 2019 Mitsubishi Eclipse Cross, the concept of a heater tap is not really applicable. The modern cooling and heating systems in vehicles like the Eclipse Cross have evolved quite a bit, and the traditional heater tap that was common in older cars is largely phased out or replaced by more sophisticated components. So, the simple answer is that the 2019 Mitsubishi Eclipse Cross does not use a heater tap as part of its heating system.

To understand why this is the case, it's useful to look at what a heater tap actually is and why it was used.

A heater tap is essentially a valve that controls the flow of hot coolant from the engine to the heater core. In older vehicles, this tap was operated either manually with a lever or automatically via a vacuum or electric actuator. Its job was to regulate how much hot coolant entered the heater core, which directly affected the temperature of the air blowing into the cabin. This simple valve let drivers easily adjust how warm they wanted the interior to be by restricting or allowing coolant flow.

However, many modern vehicles, including the Eclipse Cross, have moved away from this old-school setup. Instead of a heater tap, they use a combination of thermostatic controls, electronically controlled blend doors within the HVAC (Heating, Ventilation, and Air Conditioning) system, and sophisticated climate control modules. These blend doors direct airflow through the heater core or bypass it as needed, providing a smoother and more responsive control of the cabin temperature without needing to regulate coolant flow directly.

There are a few reasons why the heater tap has become obsolete or irrelevant in modern vehicles like the 2019 Mitsubishi Eclipse Cross:

• Improved Climate Control Systems - Modern climate control systems use actuators to control air blend and temperature instead of relying on coolant flow regulation. This results in finer temperature adjustments and better passenger comfort.
• Reduction in Mechanical Complexity - Removing the heater tap simplifies the cooling circuit. This reduces potential leak points and maintenance issues related to the valve or associated hoses.
• Enhanced Engine Cooling Efficiency - Constant circulation of coolant through the heater core can assist with overall thermal management, so keeping the coolant flowing continuously rather than throttling it with a tap is beneficial.

So if you own a 2019 Mitsubishi Eclipse Cross and are looking for a heater tap as part of maintenance or replacement, you won't find one. Instead, the heating system relies on electronic controls and blend doors that direct airflow across the heater core to regulate cabin temperature effectively. This means the focus for servicing is usually on related components such as the heater core itself, blend doors, actuators, and the vehicle's climate control module rather than a valve controlling coolant flow.
