Heater Tap on the 2017 Nissan Pulsar: What You Need to Know

When it comes to the 2017 Nissan Pulsar, you might be wondering whether a heater tap is part of the cooling and heating system. After checking multiple technical sources, it turns out that the 2017 Nissan Pulsar does not use a heater tap. Instead, this model employs an electronically controlled coolant system that manages the flow of coolant to the heater core without the need for a manual or mechanical heater tap. Let's explore why this design choice was made and what it means for Pulsar owners.

Older vehicles often had heater taps installed as a valve to manually control the flow of hot coolant to the heater core. This allowed drivers to regulate the temperature of the cabin heating manually or simply shut off heater operation to save on engine heat for other purposes. However, modern vehicles like the 2017 Nissan Pulsar have largely moved past this setup due to advancements in engine management and climate control systems.

Instead of relying on a heater tap, the Pulsar uses an electric blend door inside the heater box that adjusts the mix of heated air and cooler air to achieve the desired temperature set by the driver. The coolant runs continuously through the heater core as long as the engine is at operating temperature, while the blend door controls how much warm air enters the cabin. This makes the traditional heater tap redundant and unnecessary.

So why exactly is a heater tap not used on the 2017 Nissan Pulsar? The reasons come down to efficiency, control, and reliability. A heater tap is a mechanical valve that can wear out or become stuck over time, causing problems with heating performance or coolant leaks. By switching to an electronically controlled system with an internal blend door, Nissan eliminated these potential failure points. Also, this system is easier to control accurately, allowing drivers to quickly and smoothly adjust cabin temperature through the climate control interface without fiddling with valves.

Because the Pulsar does not have a heater tap, there's no need for Pulsar owners to worry about its maintenance or replacement during service visits. Instead, servicing should focus on other key components of the cooling and heating system:

• Checking coolant levels and condition to ensure efficient heat transfer
• Inspecting radiator hoses for signs of wear or leaks
• Examining the heater core for blockages or leaks
• Testing the HVAC blend door operation to confirm proper cabin temperature control
• Monitoring the thermostat and water pump for reliable engine coolant circulation

For Nissan Pulsar drivers who notice problems with cabin heating, such as lack of heat or inconsistent temperature, the issues are rarely related to a missing or faulty heater tap, since none exists in this model. Instead, these symptoms could point to coolant circulation problems, a faulty thermostat, an airlock in the cooling system, or an issue with the heater core or blend door actuator. Diagnostics will typically involve checking the coolant system pressure, engine operating temperature, and HVAC controls rather than inspecting a heater tap valve.

During routine servicing of the Pulsar's heating and cooling system, mechanics will perform a coolant flush and refill at recommended intervals, usually every few years, to maintain system efficiency and avoid corrosion build-up. They may also clean or replace the cabin air filters which help keep the airflow clean and effective, further ensuring a comfy cabin climate. The blend door actuator and related climate control electronics also get tested to ensure that temperature controls respond perfectly when adjusted by the driver.

In essence, the 2017 Nissan Pulsar's design omits the traditional heater tap in favour of modern, electronic climate control technologies. This means fewer mechanical parts that could fail, smoother temperature adjustments, and overall better reliability and comfort for the driver and passengers. Without the need for a heater tap, Pulsar owners can enjoy peace of mind knowing their heater system is built to be straightforward and low maintenance.

So if you're servicing your Pulsar or troubleshooting heating issues, concentrate your efforts on the cooling system, heater core, and HVAC controls rather than hunting for a heater tap or worrying about its replacement. That way you'll keep your Nissan Pulsar's heater system working just right to keep you cosy all year round.
