The defect
Unsatisfactory engine operation and throttle valve sticking may occur under long hours of high speed driving in outside temperatures of approximately 20 degrees fahrenheit and below. This IS caused by condensed water vapor drawn from the crankcase ventilating system which ices up the carburetor. This can lead to gradual loss of vehicle power and eventual stalling of vehicle.
The remedy
Dealer will equip all affected vehicles with a revised design crankcase ventilation and carburetor shield. An automatic temperature control, designed to shoot hot air into the carburetor to reduce icing, will also be installed. This will be done without cost to owner.
