What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationEngine Overheating Customer Complaint/Technician Observation: Customer complaint may include engine “overheating”. Discussion: When dealing with a customer complaint of engine ”overheating”, it is most important to understand exactly what the customer’s definition is of “overheating”. An explanation from the customer of what exactly happened is necessary. Overheating descriptions could include warning lamp(s), messages in the cluster, steam/smoke coming from under the hood, gauge “running higher than normal”, actual engine temperature higher than what the customer considers normal, smells hot, coolant leaking under the vehicle, etc. Observed engine operating temperatures of 245 F (118 C) degrees or lower are typical and are NOT considered overheating.
