Introduction

If you are a proud owner of a 1999 Audi A6 2.8L, then you know how important it is to keep your car in top-notch condition. One of the essential components of your vehicle is the auxiliary water pump. It helps regulate the temperature of your engine and keeps it running smoothly. However, if you are experiencing issues with the pump, then it's time to locate it and get it fixed. In this article, we will guide you through the process of finding the aux water pump location in your 1999 Audi A6 2.8L.

What is an Auxiliary Water Pump?

Before we dive into the location of the pump, let's first understand what it is and how it works. The auxiliary water pump is responsible for circulating coolant through the engine block, heater core, and the auxiliary heater. It operates independently of the primary water pump and only works when the engine is running. The pump prevents the engine from overheating and ensures that your vehicle's interior remains warm during cold weather.

Locating the Auxiliary Water Pump

The auxiliary water pump is located on the left side of the engine compartment, near the firewall. To access it, you need to remove the engine cover by releasing the clips on both sides of the cover. Once the cover is removed, you will see the pump attached to the coolant hose that runs from the engine to the heater core. The pump is a small, cylindrical-shaped device that has two electrical connectors and two coolant hoses attached to it.

Removing the Auxiliary Water Pump

If you need to replace the pump, then you need to remove it first. Start by disconnecting the electrical connectors by pressing the tab and pulling them away from the pump. Next, use pliers to remove the clamps that hold the coolant hoses in place. Once the clamps are removed, gently pull the hoses away from the pump. Be sure to have a container handy to catch any coolant that may spill out. Finally, remove the two bolts that secure the pump to the engine block and lift the pump out.

Installing the Auxiliary Water Pump

To install the new pump, follow the removal process in reverse. Start by attaching the pump to the engine block and securing it with the two bolts. Next, reattach the coolant hoses and tighten the clamps with pliers. Finally, reconnect the electrical connectors by pushing them into place until you hear a click.

Conclusion

In conclusion, the auxiliary water pump is a critical component of your 1999 Audi A6 2.8L. If you are experiencing issues with the pump, then it's essential to locate it and fix it promptly. By following the steps outlined in this article, you can easily locate, remove, and install the auxiliary water pump. Remember to take all necessary precautions when working with coolant to avoid injury. If you are unsure about any step, it's always best to seek the help of a professional mechanic.
