About this problem
Coolant carries heat away from the engine to the radiator. Leaks from hoses, the water pump, the thermostat housing, the radiator or internal gaskets let the level fall until the engine overheats. Owners usually notice a sweet smell, puddles, a low-coolant warning or a temperature gauge climbing. Driving an overheating engine even a short distance can warp the cylinder head.
Across all owner complaints filed about the Chevrolet Cruze since 2012, 365 (12.2%) describe coolant leaks and overheating, making it the most reported problem we track on the Cruze. The reports cluster on the 2012, 2013 and 2014 model years, and the 2012 drew the most, with 104. It tends to show up in the middle years of ownership: half of the owners who gave a mileage were between 46,000 and 101,000 miles. 13 reports describe a crash or fire linked to it. No recall covers it, but Chevrolet has sent dealers service bulletins about it, listed below.
