Overheating malibu maxx need help

Hi - Dave here, contributing to RepairPal and providing expert advice since 2010. Quick first question: Is your cooling fan working? Does it turn on when the engine temperature gets higher? Does it even turn on with the climate control system turned on? A fan that does not work properly can be a major contributor to cooling system issues. It's a good place to look - even before water pump, thermostat, and so forth. Beyond that, it's good to reach out to a trusted shop near you for more guidance. https://repairpal.com/auto-repair-near-me Click the link to find some shops near you who can help out!
