Heater Tap on the 2019 Mitsubishi ASX: What You Need to Know

When diving into the details of the 2019 Mitsubishi ASX and its heating system, one question that often pops up is whether this model uses a heater tap. Simply put, the 2019 Mitsubishi ASX does not have a heater tap fitted. This might surprise some, especially those familiar with older vehicles or specific makes that use this component, but there's a good reason for it.

Heater taps used to be common in many cars as a basic way to control the flow of hot coolant into the heater core. Essentially, a heater tap is a valve installed in the heater hose, allowing the driver or mechanic to turn on or off the flow of hot coolant that heats the cabin. This helped regulate cabin temperature and made heater repairs or replacements a bit simpler. In older cars, it was an easy and cost-effective method to modulate heat.

So why doesn't the 2019 Mitsubishi ASX use a heater tap? Modern vehicles like the ASX have moved on to more sophisticated and reliable systems to regulate heat inside the car. Instead of a manual valve in the heater hose, the ASX employs a blend door system controlled by the climate control unit. This blend door adjusts the mix of hot and cold air that you feel in the cabin without the need for any manual coolant flow control.

The blend door system is more efficient because it uses the engine's cooling system more effectively and allows the climate control computer to finely tune the cabin temperature. Heater taps are a bit old school, prone to leaks, and can cause issues if the valve sticks or the hoses degrade. By ditching the heater tap and relying on an electronic blend door, the 2019 ASX can provide safer, more consistent heating without maintenance issues related to coolant flow valves.

Another reason for the heater tap's absence is the overall engineering improvements in the vehicle's cooling and heating system. The Mitsubishi ASX uses electric water pumps and sophisticated thermostats and flow control devices that precisely manage engine coolant circulation. This ensures the engine warms up quickly and maintains optimum temperature, which directly benefits cabin heating performance without needing a heater tap.

Because of these reasons, if someone is servicing a 2019 Mitsubishi ASX, they won't find a heater tap to inspect or replace. Instead, maintenance typically focuses on ensuring the coolant system is in good shape, including things like checking the thermostat operation, inspecting coolant hoses for cracks or leaks, and servicing the coolant itself. The blend door actuator and climate control electronics are more commonly serviced or diagnosed if there are heating issues inside the vehicle.

In terms of servicing tips specifically related to the heating system on the 2019 Mitsubishi ASX:

• Keep an eye on the coolant level and quality. Using the recommended Mitsubishi coolant and keeping it topped up prevents overheating and ensures proper heating performance.
• Check for any coolant leaks around the heater core hoses and radiator connections. While there is no heater tap to fail, leaks elsewhere can affect heating efficiency.
• If the heater stops producing warm air, it might be worth having the blend door system checked by a professional. Blend door actuators can wear out or get stuck over time.
• Thermostat malfunction is another common cause of heating problems to watch for since it controls how quickly the engine reaches operating temperature and how much coolant flows through the heater core.

In short, while the 2019 Mitsubishi ASX does not use a heater tap due to advancements in automotive climate systems, this brings several benefits including more reliable and precise control of cabin heating. Maintaining the cooling system and climate control electronics is the best way to keep the heater working smoothly instead of worrying about taps or valves that were commonplace in older cars.
