Ford Mustang heater core leaking issue requiring replacement on Ford Mustang

Some Ford Mustang owners report experiencing issues with a leaking heater core, often indicated by a sweet smell of coolant when the heater is on. The replacement process can be complex, sometimes requiring the removal of the dash pad, which involves unscrewing multiple screws to access the core. Additionally, while heater cores are relatively inexpensive at around $45, owners should factor in labor costs and any additional parts needed for the replacement. Some owners have found that heater cores with extended tubes for easier hose connection in the engine bay can be beneficial. To help prolong the life of the heater core, regular coolant changes as part of seasonal maintenance are recommended. For those unfamiliar with the replacement process or lacking the necessary tools, seeking professional assistance is advisable to ensure the replacement is done correctly.
