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.
Thermostatic Air Cleaner: Operation
When engine is cold, the thermostat in snorkel senses low air temperature and closes the air door to prevent entry of cold, outside air. At this point, only heated air from around the manifold shroud enters carburetor. As the thermostat senses warmer temperatures, it begins to close off the air door to heated air and allow outside air into the carburetor. In this manner, the temperature of incoming air can be controlled.
