This video explains how to install an air bleeder port/screw, how to bleed the air on a coolant system, and an overview of coolant parts under the hood. This information can be applied to most vehicles but is directed towards Nissan Frontier and Xterra and along with the Suzuki Equator that has the VQ40DE. This process of bleeding does not need to have extra tools like a venturi vacuum or compressor.
Here are the three top reasons you know you have air in the system.
1. No heat when stopped.
2. A sound of water movement near the riders dash when vehicle moves forward or stops.
3. Overheats.
