Parts for your 2020 Subaru Impreza-Heater tap

Does the 2020 Subaru Impreza Have a Heater Tap?

When it comes to the 2020 Subaru Impreza, a common question among DIY mechanics and car enthusiasts is whether it features a heater tap. After diving into technical manuals and manufacturer insights, it's clear that the 2020 Impreza does not use a heater tap as part of its heating system. But what exactly does that mean, and why is this the case for this particular model?

A heater tap is a small valve traditionally found in the cooling system of older vehicles. It controls the flow of hot coolant from the engine to the heater core, effectively regulating cabin temperature by allowing or blocking the flow of heat. This manual valve was often used to fine-tune heater performance, especially before modern electronic climate control systems became standard. However, for the 2020 Subaru Impreza, such a device simply isn't present because of how its HVAC (Heating, Ventilation, and Air Conditioning) system is designed.

Modern vehicles like the 2020 Impreza rely on an electronically controlled setup. The heating control is managed primarily through a blend door actuator inside the HVAC unit, which regulates the mix of heated and cooled air entering the cabin. Instead of manually or mechanically controlling coolant flow through a heater tap, the Impreza's climate control module adjusts the blend door position based on temperature settings made by the driver or automated climate system. Coolant is constantly circulated through the heater core when the engine is running so that heat is readily available on demand.

There are a few solid reasons why the 2020 Subaru Impreza does away with the heater tap approach. Firstly, removing the heater tap simplifies the cooling system plumbing, reducing the chance of leaks or valve failures. Secondly, electronically controlled blend doors afford more precise and reliable temperature control over manual valves, improving passenger comfort. Lastly, overall system complexity and servicing needs are reduced, meaning fewer points of potential failure and a smoother ownership experience.

Because the heater tap is not part of the 2020 Impreza's design, owners won't need to worry about this particular component when servicing or troubleshooting heating issues. Instead, any heating performance problems are more likely to stem from components like the heater core, coolant temperature sensors, the thermostat, or the electronic blend door actuator. Regular maintenance should focus on the wider cooling system, ensuring coolant levels are correct and that the cooling system is flushed and replaced as per Subaru's servicing schedule.

To recap, the missing heater tap in the 2020 Subaru Impreza is a direct result of advances in vehicle heating technology and climate control design. While older cars might need to check or replace a heater tap to maintain cabin warmth, the Impreza relies on electronically controlled airflow and a constant flow of engine coolant through the heater core. This tends to improve reliability and ease of use for drivers, with fewer moving parts between the engine and your legs on chilly mornings.
