| SSPA2 | 2017-09-14. Service bulletin. ENGINE AND ENGINE COOLING:COOLING SYSTEM. Mazda Motor Corporation has decided to conduct a Special Service Program (SSP) on certain 2014-2016 Mazda3 vehicles built at the Mexico plant from December 4, 2013 through September 23, 2015. On certain subject Mazda3 vehicles, the concentration of engine coolant filled at the plant may not be appropriate, which could reduce the cooling or heating performance. With the deterioration of cooling performance, the coolant temperature may increase at high engine load, and a warning light (high engine coolant temperature warning light) may flash or illuminate, resulting in the engine possibly overheating. Dealers are to check the concentration of engine coolant, and replace the coolant if necessary. The check and repair must be performed at no charge to the vehicle owner. This campaign expires March 1, 2017. |
