Summary
14371B - SPECIAL COVERAGE (LABOR CODE REVISED). SOME 2011-2014 MODEL YEAR CHEVROLET CRUZE VEHICLES AND SOME 2012-2014 CHEVROLET SONIC VEHICLES WITH THE 1.4L ENGINE MAY HAVE AN ENGINE COOLANT LEAK FROM THE WATER PUMP. THE PUMP MAY LEAK FROM THE WEEP RESERVOIR OR FROM THE WATER PUMP SHAFT SEAL, LEADING TO A DRIP OF COOLANT ONTO THE ENGINE OR ONTO THE GROUND. OVER TIME, THE LOSS OF COOLANT WILL REDUCE COOLING PERFORMANCE AND EVENTUALLY COULD LEAD TO ENGINE OVERHEATING. IF THIS CONDITION IS NOT CORRECTED, THE “SERVICE ENGINE” INDICATOR LIGHT MAY COME ON, AN “ENGINE HOT, AC OFF” MESSAGE MAY APPEAR, A CHIME MAY SOUND, AND THE ENGINE POWER MAY BE REDUCED. IF THE CONDITION OCCURS WITHIN THE SPECIAL COVERAGE TERMS,, THE WATER PUMP WILL BE REPLACED IF LEAKING.
