Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Conventional Thermactor Air
The Conventional Thermactor Air injection system reduces the hydrocarbons and carbon monoxide entering the exhaust gases. This gas reduction is achieved by injecting clean air into the exhaust gases.
Clean air is injected into the exhaust manifolds. During system operation, some of the air is dumped to the atmosphere to prevent excessive exhaust heat. Operation of a belt driven vane type air pump provides the air supply. Air control valves, check valves and various air distribution lines provide air injection.
