Automatic Hot Air Intake System: Description

This system leads a hot air supply to the carburetor in cold weather to improve driveability and prevents the carburetor from icing in extremely cold weather. All models use a thermostatic valve to control opening and closing of air inlet door. Celica, Corona and Pickup models use a separate thermal vacuum valve to operate the heated air door. All other models use a hot idle compensator (HIC) valve.
