In the 2015 Chevy Spark, there are multiple areas where coolant may escape. The coolant travels from the radiator to the water pump, then into the engine, and also into the heater core when the heater is in use. This system is closed-loop with various points where leaks could occur. The primary reason for leaks is typically a damaged radiator hose, whether it is the upper or lower hose. Over time, the rubber material may deteriorate and develop cracks, leading to leaks. Another possible culprit is a malfunctioning water pump or its gasket that can cause coolant to seep out. Moreover, a failing head gasket could result in leaks around the head's edges. If there is coolant leakage within the passenger compartment, it indicates a heater core malfunction, which can be the most expensive repair.
My expansion tank had a leak, but it was a simple and inexpensive fix.
If your 2015 Chevy Spark is leaking coolant, it may be because of a malfunctioning radiator hose, water pump, or another hose. It's important to have your vehicle checked promptly to prevent potential overheating problems.
