Heater Tap on the 2016 Holden Colorado: What You Need to Know

If you're looking into the heating system of the 2016 Holden Colorado, you might have come across the term "heater tap" and wondered whether this part plays a role in your ute's setup. When it comes to the 2016 Holden Colorado, the straightforward answer is that it does not use a traditional heater tap in its cooling and heating system.

The heater tap is an older component more commonly found in vintage cars and some early modern vehicles, especially those from the pre-2000s era. Its main job was to control the flow of coolant to the heater core manually. By turning the tap one way or another, drivers could regulate how much hot coolant entered the heater core, thus controlling the heat output inside the cabin.

In the 2016 Holden Colorado, however, the heating system utilises a more modern and efficient approach. Instead of a manually controlled heater tap, it uses an electrically controlled blend door and heater control valve system. The blend door inside the heater box adjusts airflow, mixing hot and cold air to achieve the desired temperature. The heater control valve, on the other hand, allows controlled flow of hot coolant to the heater core but is electronically actuated rather than manually operated like a traditional tap.

So why is there no heater tap on this Holden Colorado? Here are a few reasons:

• Modern climate control systems: The 2016 Holden Colorado's HVAC (heating, ventilation, and air conditioning) system uses electronic controls to provide a precise and user-friendly way of adjusting cabin temperature. This system replaced the manual heater tap for better efficiency and ease of use.
• Improved comfort and control: Electronic valves and blend doors allow for smoother temperature changes. Drivers can adjust temperature precisely through knobs or digital climate control units rather than fiddling with taps.
• Reduced maintenance and increased reliability: Mechanical heater taps can seize or leak over time. By eliminating these manual components and shifting to electronically controlled valves, Holden reduced potential leak points and overall maintenance hassles.
• Compliance with emissions and safety standards: Modern coolant and heating systems must integrate with vehicle electronics and emissions control systems. The heater tap as a standalone mechanical part does not offer the fine-tuned control required by newer vehicles.

All this means that if you're servicing the heating system on a 2016 Holden Colorado, you won't be looking for a heater tap specifically. Instead, you'll want to focus on components like the heater control valve, blend door actuators, coolant hoses, and the radiator and thermostat - the key players keeping your cabin cosy and your engine cool.

For those who want to keep their Colorado's heater in top shape, servicing is straightforward but important. The heater control valve, often controlled electronically, can sometimes fail or develop leaks. Watch out for signs such as reduced cabin heat, coolant smells inside the vehicle, or coolant puddles under the ute. These symptoms might point to a faulty heater valve or related hose issues.

Regularly checking coolant levels, flushing the cooling system as per the maintenance schedule, and inspecting hoses can also prevent heating problems. Since there isn't a heater tap to turn on or off manually, you won't have the chance to isolate the heater core by hand, so keeping those valves and actuator mechanisms in working order is essential.

Should you notice any issues with heater operation, mechanics often recommend testing the heater control valve's functionality and inspecting the blend door mechanism inside the dashboard. Replacement parts must be compatible with the Colorado's electronic climate control system, so genuine or high-quality aftermarket parts are best.

In the end, the absence of a heater tap in the 2016 Holden Colorado reflects the shift towards enhanced technology and comfort. The electronic controls mean less manual fiddling and more dependable heating through all seasons.
